On ViewHill Art Foundation Three Christs, Sleeping Mime, and the Last Supper; Pagan Paradise: Charles Ray and the Hill CollectionSeptember 28 February 15, 2020New York
Charles Ray is a slippery artist for me. In the time that I have been engaging with his work, I have often been surprised by what gives me pause, and by what I find myself returning to days, sometimes even years, after I have seen it. So often, it is something slight: witnessing the slow ripples created by the edges of a womans fur sleeve as it dragged through Ink Box (1986), installed in Rays 1998 Whitney retrospective; observing the sheen of flowing ink in 1987s Ink Line and becoming aware, before even reading the title or anything about it, that the line moved. I wondered what, if anything, would strike me when I visited the Hill Art Foundations current exhibition, Three Christs, Sleeping Mime, and the Last Supper; Pagan Paradise, which is curated by Ray from the Foundations collection and features, in addition to four of his own pieces, intimately-scaled bronzes made by Italian, French, and Netherlandish sculptors of the 16th and 17th centuries.
While viewing the show I was confident that Golden Jewelry (undated), a tiny shriveled apple, complete with gold stem, gifted by the artist to his wife, would make the greatest impact. But no: what I have been turning over, again and again, is Rays recumbent Mime (2014), and more precisely, the sleeping Mimes soft-soled shoes. They are aluminum, as is the rest of the sculpture, and presumably metallurgically stiff, but visually they are also undeniably ductile and respond believably to the figures bony feet. Similarly, the aluminum cot on which Mime rests strains and bows under his weight: we can notice these effects if we get down on our hands and knees because the sculpture does not sit flat on a podium. Instead, it rests lightly on the floor on the four legs of the cot, rendered fully in the round, even underneath. And then there is the fact that these qualities were not made by the artist at all. Rather, Mime was carved by a robot, as Ray writes in an essay that accompanies the exhibition. Any visible hand is purely metallic, the materials or the non-human makers.
The effects created by the surface finish of Mime are further explored in a sterling silver sculpture nearby, Mountain Lion Attacking Dog (2018), which Ray describes as an essay in mark making. This work portrays, through different methods of chasing, the respective pelts of its animal protagonists. Rays attention to such technical challenges also creates a dialogue with the Renaissance and Baroque sculptures he has selected to appear in the exhibition. The installation is a lesson in withholding: there are only nine pieces included over the two floors, with every wall-mounted object given its own wall and each sculpture in the round provided its own generous floor space. As a result, we can draw quite close to objects that would more often be seen sharing cases with others.
This decision provides opportunities to note, for example, the ripping flesh of Barthelemy Prieurs Lion Devouring a Doe (probably cast before 1583), the fact that the grotesque figure in Adriaen de Vriess Bacchic Man: Lomazzo Personifying the Accademia della Val di Blenio(cast circa 1578-1580) wears a mask (seen from a distance, this is very difficult to understand), or the varying patina of Alessandro Algardis Christ at the Column (circa 1630s), molten chocolate across Christs back, but lighter and more mottled at the knees and the back of his legs. This suggests the touch and caress of an earlier owner (or owners), and, while we cant embrace the sculpture ourselves, Christ at the Column, in the company of Mime, encourages us to imagine the materials properties and the strangely animated suppleness that is at play here. Algardis Corpus Christi (circa 1646), suspended high and alone on the gallerys stark white wall, emphasizes its figures enunciated fingers and toesas Ray comments, the Algardi Christs are depicted as if alive, and this articulation is mimicked in the splayed toes of Rays attacked Dog. Antonio Susinis gilded bronze Cristo Morto (circa 1590-1615) is hung at head height so that we can easily make out his bulging eyes. This Christ is truly dead, or so the artist makes the sculpture and its bronze mediumone I just described as livingseem.
Materiality, finish, the artists hand or lack thereof, and the imitative potential of sculpture: Ray is, in this installation of his work and its important bronze precedents, presenting a philosophical discussion of sculptural possibility. In his essay, Ray asks, Does my mime sleep, or does he mime sleep? and his question is justified: sculpture can only ever mime the real. Mime does not sleep or dream; the apple will never fully rot; statues of Christ are neither living nor dead; and the dog and doe let out no heaven-rending scream.

Seasoned art dealer and collector Jens Faurschou did not make the decision to open a branch of his foundation in New York lightly, even though he has already been through the process twice before in other cities.
Weve done it for manyyears in Copenhagen, for many years in Beijing, and thought, Now, we dare to try New York,' the soft-spoken Faurschou told Artnet News ahead of this weekends opening of his sprawling ground-floor space in Greenpoint, Brooklyn, a former shoe factory converted into a sleek art venue by architect Markus Dochantschi.
In recent years, New York has become home to a number of private museums dedicated to the collections of wealthy tycoons, from J. Tomilson Hills space in Chelsea to the Brant Foundation in the East Village.Faurschou, however, has a far lower profile in the United States than the others, and prefers to let his art collectionfull of blue-chip names but also impractical installations with political themesspeak for itself. And in contrast to private museums that quickly become Instagram magnets, theFaurschou Foundations inaugural display avoids relying too heavily on eye candy, offering a more balanced visual diet.

Faurschou, who made his money selling international contemporary art in his native Denmark and established his eponymous foundation in 2011, did not even know where Greenpoint was when he set out to open in the city. But after opting out of other New York City spaces, such as one in Harlem that did not offer a ground-floor option, he found the industrial space in the fast-changing, gentrifying neighborhood to be just what he was looking for.
We went out and found this building and I was amazed, he said. If you take an Uber, its quicker than going from Chelsea to Upper East Side or Midtown. Then we started to look around the area and its lovely. It has its own life with a lot of great small restaurants and shops.

In a city with seemingly endless art options, the next hurdle for Faurschou was to figure out how to stand out. New York representsa big challenge because we have to do something where we show who we are and what we can do, he said. He and his teama small operations staff in New York, plus his wife Masha and his three children at homedecided to debut with a group exhibition that would offer a sampling of the artists in the collection.
The result is a thought-provoking and often startling show of international all-stars titled The Red Bean Grows In The South, which touches on topics ranging from the notion of longing to political passions and the desire to break free from repression.

With work by roughly 17 artists including Ai Weiwei, Georg Baselitz, Louise Bourgeois, Cai Guo-Qiang, Tracey Emin, Edward and Nancy Kienholz, Yoko Ono, and Danh Vo, the show also reflects what Faurschou says is a core part of the foundations identity: a longstanding relationship with China and a desire to engage Western audiences with important ideas from the region.
According to the catalogue essay, the inaugural presentation revolves around themes of violence, war, politics, idealism, escapism, desire, hope, dreams and memory, which would sound like a lofty goal were it not so seamlessly executed here.
Faurschou says the display came together somewhat organically. The first pairing seemed somewhat random at first: Georg Baselitzs painting Mit Roter Fahne (With a Red Flag) (1965), which depicts a humiliated soldier returning home from war with a diminutive head and tattered uniform, and Paul McCarthys monumental CSSC Frederic Remington Charles Bronson (201416), which shows the eponymous film star with an outsize cowboy hat riding what appears to be a disintegrating mashup of a melting saddle and a tangled mess of horse legs and hooves.

You would never really think of putting them together but it just workedyou have this hero coming back from the war and you have Charles Bronson on a horse where the whole structure is falling apart,Faurschou said. Maybe even more surprising for me is that [together] they have such strong visual impact. Thats very important.
This is classic Faurschouhe brings years in the art business to bear on his choices, but he is also willing to let serendipity and instinct take its course. When installing one prominent gallery, for example, where Cai Guo-Qiangs A Boat with Dreams (2008) hovers from the ceiling above Alison Saars haunting life-size sculpture Dying Slave (1989), Faurschou said, We are missing something.
It so happened that his son Christian had just returned from a visit to the National Gallery ofDenmark to see an exhibition of the work of Danh Vo, who often explores cultural history and the meaning of artistic collaboration in his work. You need these prints, he told his father. The body of work presented photos taken by Joseph Carrier, a counterinsurgency specialist in Vietnam from 1962 to 1973 who later became a close friend of the artist. By the time he was forced to leave Vietnam by American authorities because he was gay, Carrier had produced a substantial photographic archive, which he later bequeathed to Vo.
On a whim, Faurschou called up Vo, and the artist happened to be in Denmark. The rest, as they say, is history. Vos work,Photographs of Dr. Joseph M. Carrier 19621973 (2010), now lines the perimeter of Saar and Cais gallery.

Then I got excited, Faurschou recalled. Theres a connectionbetween the rooms all kind of getting together.Look no further than rooms like one featuring Yoko Onos devastating video Happy Xmas (War is Over) (1971/2003), a compilation of disturbing images that run counter to the iconic John Lennon song. It hangs above a large sculpture of menacing bent saws by Robert Rauschenberg, another artist who was horrified by the Vietnam War, titled Lurid Attack of the Monsters from the Postal News (August 1875).
Also immediately visible from the entrance isEdward and Nancy Kienholzs massive installationThe Ozymandias Parade (1985), which brings together objects the couple collected from flea markets across Europe. (The work is perhaps the only major installation by the couple on view in the city, as they have not been well collected by New York museums.)

Going forward, Faurschou is planning roughly two exhibitions a year. Just dont expect the kind of hit-parade Instagram bait you might find at other institutions. Ihope with this exhibition that it makes you think. Its not just to go in and say, This was beautiful. This was fun,' Faurschou said. I think it digs deeper. And I think we live in a time where its really important that people dont live on the surface.

A two-bedroom/two bath apartment on the 14th floor of The Plaza at Five Points is on the market for $1,195,000
Lakeland residents Carol and Don Stephens have been coming to the Sarasota area for short getaways for 35 years, most of that time specifically to Longboat Key where they enjoyed beach condominium living, views of the Gulf of Mexico and days of subline relaxation. But, several years ago they decided they wanted a different kind of experience an escape to the city.
"We had been hearing a lot about Sarasotas downtown with its lively cultural scene and we thought that would be just the thing," said Don Stephens. "We wanted to be close to walking distance if possible theaters, galleries, restaurants, shopping, the opera, you name it. We wanted a place where we could park the car, unpack and then enjoy the action. And hopefully not see the car for the next week or so."
When a 14th floor, two-bedroom apartment became available at The Plaza at Five Points, the couple knew they had found their launch pad for fun, as well as two deeded garage parking spaces.
The 1,671-square-foot luxury dwelling has an extra-large covered terrace accessed by both bedrooms and the living room which frames views of Sarasota Bay and metropolitan life. The couple bought the condominium in 2012 primarily because of its location, right in the middle of everything, and were then charmed by their apartment and The Plaza at Five Points building, which has 49 units (four penthouses) and was built in 2005. Its a mixed-use complex. The condominiums begin on the 11th floor. Below that offices, financial services, retail, a bank.
Carol Stephens, an interior designer, furnished her sky-box with urban polish and custom amenities, the way she would a permanent full-time residence so that she and Don would have every convenience and comfort if they were in town for two days days or two weeks. The double door front entrance opens into a lavish foyer and has views across the living room out to the terrace and beyond.
The large rooms express a relaxed elegance with special features such as grasscloth walls in the kitchen, dark granite counters, double vanities in the master and guest baths, artistic lighting, and custom built-ins. She installed wide-plank hardwood floors in the living room, hall and master bedroom. When the couple moved in, the apartment had two generous walk-in closets, which was more storage than they needed. So, Carol converted one of them into a home-office for Don.
The Plaza building itself, apart from its prime location, has been a source of pride for the homeowners. "We love that The Plaza is pet friendly because we have an eight-pound Yorkie whom we take to the park across the street everyday," said Don. "The Plaza has valet parking, guest parking, full-time maintenance management and it is impeccably cared for. We could not ask for more."
These homeowners have also appreciated the 10th floor open-air residents private oasis which includes a heated swimming pool and spa, summer kitchen, outdoor shower, rooftop gazebo, and inside a fitness center and conference room. Theres also a large community room with lounge and catering kitchen.
Carol and Don Stephens have loved everything about their downtown condo with the urban vibe. But, recently the couple put their vacation getaway on the market. It is listed at $1,195,000 through Thomas Netzel of Sothebys International Realty and it is being sold turnkey.
"The reason were giving it up is that we just dont use this wonderful place like we used to" said Don. "Our children and grandchildren are in Lakeland and we are involved in their lives and we want that to be the case. Friday nights for us lately are spent at a high school watching the grandkids in some sporting event.
"The last time Carol and I came to Sarasota for a weekend of city fun, we realized we handt been there for six months. It was a reality check and we both realized its time for somebody else to have The Plaza apartment experience and enjoy the kind of urban getaway we enjoyed for the past seven years."
Five Points, the intersection of Main, Central and Pineapple streets in downtown Sarasota, has been the center of commercial activities since settlers began to arrive in 1885, the date the Scots first came. Where The Plaza condominium is now, there was originally a wooden boarding house constructed in 1886 to accommodate new arrivals and construction workers. That building was demolished in 1924 to make room for First Bank and Trust Building, the areas first skyscraper. It had seven stories and an elevator, which alarmed as many neighbors as it impressed.
Other banks have continued to occupy that corner right up to today. Retail, restaurants and offices are on the lower floors of the Plaza at Five Points. A large clock that faced two ways was a signature feature of the bank (s) that have stood tall at Five Points. Theres still a clock today but its across the street at the entrance to Selby Park at Five Points.
The area that is today a lighted round-about with flags has traditionally been called the triangle at Five Points. In Sarasotas earliest days there was an artesian well, drinking fountain, hitching post and a trough for cows, horses and other thirsty livestock that wandered by. In 1911 community authorities outlawed meandering cows at Five Points. Later the triangle was the site of a World War I memorial.
Five Points has always been considered the hub of the city of Sarasota and today people who live at The Plaza at Five Points or work in one of the offices in the building are keeping history alive as well as enjoying modern urban amenities. Five Points was in the middle of the action when Sarasota was a struggling community of settlers intent on prospering and it still is today.

Part one of this series focused on slab preparation and sub-base installation. In the article, we learned the importance of a well compacted and smooth subgrade, as well the proper installation of formwork, jointing, vapor barriers and other reinforcement. This article will discuss the next steps to placing, finishing, sawing and curing medium to large concrete slab on grade.
Rate of placement and screeding method are baseline decisions that must be made prior to start of placement. Placing/finishing concrete is time sensitive and susceptible to environmental conditions. Ideally you want to work within an 8- to 16-hour window for place, finish and cure/saw cutting operations.Uniform mix batch to batch and slab edge boarded.Chad White
Major considerations when scheduling concrete and planning day of placement activities include:
Planning Tips
For the purpose of this article we will be discussing concrete placement rates of 60-200 cubic yards per hour and strike-off rates of 4,0008,000 square feet per hour. Formwork and strike-off will dictate the FL numbers. Uniformity of slump and rate of placement will greatly influence FF numbers and panning/finishing processes.Roller tamp attachment to laser screed.Chad White
FF60/FL40 is the new norm for warehouse and open slab placements. Automated raking and screeding of slabs will result in higher production rates and flatter floors.
Major considerations when placing concrete include:
Installation Tips
Finishing floors is all about flatness, burnish and attention to detail. Timing of finishing steps is a critical factor and must be judged in real time.Blending edge burnish.Chad White
Major considerations for finishing concrete slabs include:
Tips for Finishing
Curing is either spray-on membrane or wet cure with blankets. There are pros and cons to both systems, and individual project requirements may dictate choice. The important thing with curing is timeliness and adherence to manufacturers and project specifications.Installing wet cure blankets.Bob Simonelli
Timing is probably the key coordination factor with saw cutting operations. A skilled crew and good equipment are required. There is nothing worse than having a great looking finish marred by crooked or spalled cuts.
Major considerations for installing control joints and curing include:
Tips for Sawing/Curing
Control and conditions of access during the placing/curing period is probably the biggest component to a slab protection plan and the hardest to police. Ensure slab protection plan is communicated to all trades. Advocate for daily cleaning by floor scrubber during construction. Ensuring that a spill kit is available while the slab is being used by other trades is a must and a major component of daily housekeeping. Scratches, gouges, spills and edge destruction are major concerns when slab is being used as a work platform by general trades.
Major considerations for slab protection include:
Execution Tips
Chad White has been involved in all aspects of concrete construction from craftsman to concrete subcontractor and is a founder of WL Concrete. Whitehas personally been involved with design and construction of many industrial slabs, including shake-on hardeners, defined traffic super flats and high tolerance random traffic floors. He is the author of numerous articles regarding concrete slab on grade installationand a speaker at World of Concrete.

Next up in our review of 2019, Kristine Klein picks out the 10 most arresting installations on Dezeen, including Banky's pop-up, pink seesaws slotted between the border wall and a sauna at Burning Man.
Gross Domestic Product, UK, by Banksy
British graffiti artist Banksy opened up a "for display purposes only" pop-up shop in East Croydon to showcase his merchandise, which is for sale online. The retail space was created in response to actions by a greeting card company trying to "seize legal custody" of his name.
The installation in Croydon consists of a series of window displays that contain several works of art created by Banksy, including the stab vest worn by rapper Stormzy for a concert this summer. Many of the retail products were made exclusively for the online shop and include t-shirts and mugs adorned with the artist's famous works.

The Starry Night, The Netherlands, Ivana Jeli and Pavle Petrovi
To highlight the issue of light pollution in urban areas, Serbian artists Ivana Jeli and Pavle Petrovi installed a series of LED lights that together form Van Gogh's Starry Night over a canal in Amsterdam.
Using 1,400 acrylic rods illuminated by small LED lights the designers were able to imitate the artist's brushstrokes and recreate the painting's swirling night sky pattern.

Steam of Life, USA, JKMM Architects
Finnish studio JKMM brought a sauna to this year's Burning Man festival in the Nevada desert. To create the circular pavilion, Steam of Life, the team of architects stacked timber slabs.
The interior was lined with benches and an open atrium for cooling down and meditative relaxation formed the centre of the structure. Apart from the sauna stove, which was transported from Finland, all of the building materials were locally sourced.

Mirage house, Switzerland, Doug Aitken
American artist Doug Aitken built a ranch-style residence clad in mirrors for a site in Switzerland surrounded by mountains, where it will stay for two years. The reflective material of the building casts the scenic landscape, which changes with the seasons, across its exterior.
Inside the mirrored structure kaleidoscopic panels installed on the walls and ceilings refract light and distort the interiors.

The Secret of the Great Pyramid, France, JR
French artist JR placed a massive optical illusion made from thousands of paper stickers on the grounds surrounding IM Pei's Louvre pyramid in Paris, to celebrate the building's 30th anniversary.
The collage, which measured 17,000 square metres, formed an imaginative image that proposed the continuing underground construction of the iconic triangular structure. JR's work was only on display for one day, the museum's daily stream of visitors left the piece in shreds.

US-Mexico border wall seesaws, USA, Mexico, Rael San Fratello
Rael San Fratello inserted three pink seesaws between metal slats of the US-Mexico border wall, so that children on either side can play together. The playground equipment was inserted along the portion of the wall that extends from El Paso, Texas to Ciudad Jurez in Mexico. Rael produced the installation through a collaboration with Taller Herrera, a workshop located in Ciudad Jurez.
"The wall became a literal fulcrum for US-Mexico relations and children and adults were connected in meaningful ways on both sides with the recognition that the actions that take place on one side have a direct consequence on the other side," the designer said on Instagram.

Unzipping Milan building, Italy, Alex Chinneck
For Milan design week British artist Alex Chinneck installed a giant zipper on the face of a historic Venetian building to give the illusion that it is being peeled open. The installation was created for vape and tobacco brand Iqos.
The 17-metre-wide facade features a large zipper on its right side designed to create an opening that reveals bright lights. Inside the edifice, sculptural zippers attached to the interior walls and a circular opening on the floor also reveals glowing lights.

For Forest, Austria, Klaus Littmann
Klaus Littmann planted 300 trees in Wrthersee Stadion, a football arena, in Klagenfurt, Austria to send a message about the anthropocene, deforestation and climate change. For Forest replicates the the types of plantings typically found in European forests.
It memorialises nature as an "artistic sculpture" and was designed to gather people together so that they contemplate the environment and the importance of its protection.
After the installation closed the hundreds of trees were re-planted on a nearby plot of land. A wooden pavilion that provides visitors with educational information accompanies the small forest.

Sight, Greece, Antony Gormley
British sculptor Antony Gormley placed 29 humanoid sculptures atop hills, inside architectural ruins and along the coast line of the Greek Island Delos near the Aegean sea. Works in Gormley's collection titled Sight were made using iron and formed abstract versions of human bodies.
The exhibition was organised in collaboration with the Ephorate of Antiquities of Cyclades and commissioned by Neon, a nonprofit art foundation.

Desert X installations, USA, Sterling Ruby, John Gerrard and Pia Camil
Works by 18 artists and groups including Sterling Ruby, John Gerrard and Pia Camil were featured in a series of installations displayed at the biennial art festival Desert X in California's Coachella Valley. The arid landscape, located East of Los Angeles, is the site of the annual Coachella music festival.
Highlights of the exhibition were Sterling Ruby's monolithic rectangular block coated in fluorescent orange and Lover's Rainbow by Pia Camil, made from arched rebar, painted every colour of the rainbow. Camil realised the work as the twin for a matching sculpture located on the other side of the US-Mexico border, the piece sheds light on the current immigration policies between the United States and Mexico.

While it hardly qualifies as cutting-edge technology, the project described here did provide a solution to an annoying problem I have faced several times: How do you get a decent off-air signal from an AM station, where the studio is in a modern curtain-wall office building and is located at or beyond the 5 mV/m contour of the station?
I saw evidence that several engineers had explored solutions in the past. The hardware was still around when I arrived. A very nice (and pricey!) commercially-made shielded loop was installed on the roof with inside phantom power for its preamp in the studio racks seven floors down. That didnt really work. A better antenna signal could be had from the coax shield than from the actual loop antenna and preamp output.
Another iteration was the installation of pre-amplified loopstick antennas, taped to the window glass in one of the studios with coax routed back to the rack-mounted receivers. This, too, yielded a marginal signal enough to tell if we were on the air, but not useful for critical evaluation at all.
Yet the stations both had very usable, listenable signals on my car radio parked in the building driveway.
A COMMON PROBLEM
As is always the problem with metal-skinned buildings, the openings in the exterior walls behave like sections of waveguide at frequencies below cutoff virtually all of the field is cancelled. I concluded that no inside solution would ever work satisfactorily. Long runs of coax also werent working.
How could the car radio result be replicated in the building? To do that, I borrowed old technology and married it with some moderately-priced new technology to build what I believe is a solid solution.
I fabricated two shielded loop antennas from home center components as shown in Fig. 1. Inside the tubing is 10 turns of ordinary hookup wire. I used some multi-conductor wire and joined the ends to make one long wire length (see Fig. 2). Recall that the purpose of a shielded loop is to make the antenna responsive to only the magnetic component of the transmitted signal.
The shield is there to prevent successful capacitive coupling with electrostatic fields. Since the electrostatic fields from AM stations (and from most sources of interference) are vertically polarized, the electrostatic field induces voltage in only the vertical pieces of conduit. That same electric field exists inside the tubing as well and induces a voltage on the wire turns inside.
So how does this shielding help? Because the electric field in the vertical tubing sections induces voltage in the wire turns in opposite directions on either side of the loop. Thus the electrostatic contribution (in a perfect world) cancels. The gap in the conduit at the top of the loop (Fig. 3) is to avoid having the shield look like a shorted transformer turn, thus cancelling the magnetic component as well.
This is how your field intensity meter works. Regardless that the meter scale is calibrated in volts per meter, it is a magnetic device. The relationship between the electric field and the associated magnetic field is a known constant (120)t and the Potomac folks figure you wont be using the meter in other than an air environment, a pretty safe bet. Loop orientation works just like your field meter as well, with distinct nulls and maxima as you rotate it.
To provide just a bit of pre-selection to the loop, I added a small transistor-radio-style variable capacitor bought from an eBay seller. I calculated my ten turns to have about 200 microhenries, but with the capacitance contributed by the tubing and other unquantifiables, who knows?
My variable cap has two sections, each about 220 picofarads. I paralleled the sections and wired loop and capacitor as a tank circuit the miracle of adjustable components. Just turn the dial until it works! Tune for maximum smoke. The result is a broad resonance, but helpful for me, since my location is in the 50+ mV/m field of two other AM stations.
To couple each loop to a receiver, I used some randomly chosen ferrites found in a drawer and made a small ferrite loaded transformer for each loop antenna. I figured the impedance of the loop would be low. I guessed maybe an ohm or two. So, a 1:5 turns ratio would get me somewhere in the 50-ohm neighborhood.
NON-CRITICAL DESIGN
As youve probably guessed by now, nothing in this design is particularly critical. The radios are ordinary Panasonic in-dash models bought on eBay for about $20 each. This, too, is anything but critical.
Now, with two steerable antennas, I have a decent signal from both stations. But how to get that RF down seven floors to the studio? The answer is not to try. Instead, I installed my two car radio receivers in a weatherproof box (see below) and clamped the whole business to a railing on the roof.
The signals from two AM stations, as well as power, are carried on a piece of Cat-6 cable following the telephone riser path down the seven floors and into our leased space. Power comes up on two paralleled pairs, and baseband audio is coupled from the radio speaker outputs on the other two pairs.
The radios I used are bridge amplifier designs, meaning that the speakers are driven in a balanced, differential way, but I used small audio transformers for isolation anyway. Preserving balance yields undiminished audio quality downstairs. I also added a local headphone jack for each, allowing confirmation of proper operation before leaving the roof.
The whole business was installed into what Amazon calls a black, tactical, weatherproof case as shown in Fig. 4. Weve all seen these used for sensitive electronics that must be shipped. They have snap locks and gasketed lids. I just ordered a generously sized one and installed the shelves you see. The loop antennas attach using ordinary 3/4-inch plumbing components with the antenna coax fished through. I added reinforcement where the pipe flanges attach. Finally, the whole assembly is U-bolted to the railing.
WHAT ABOUT POWER?
Powering the system remotely involved a little I-squared-R thinking. The Cat-6 run overall was about 250 feet. Paralleled Cat-6 conductors at that distance worked out to be about 5 ohms overall. I had no idea what current the radios drew and, barely visible in the pictures, is a small lead-acid battery also in the enclosure. Its there to hold up the radios channel memory if the downstairs power needs to be disconnected for some reason. It needs to remain charged.
Finally, theres a small 12-volt fan in the box as well. I guessed 2 amps for the radios which, with 5 ohms on the way, means my 12 volts will be 2 volts on the roof. I could have done some bench measurements and built a supply, but when I can buy a 30-volt 3-amp adjustable supply with metering and overcurrent protection on Amazon for $60, why bother? The supply is pictured in Fig. 5.
With the battery disconnected, the supply voltage was gradually raised until the receivers saw about 13 volts. I then noted the current. When the battery was connected, the voltage came down to about 12.8 and the current increased by about 50 milliamperes. That seemed a reasonable amount for trickle charging one of the 7amp-hour batteries commonly used in UPS devices. Well see.
Anyway, the completed project, which is shown in Fig. 6, was simple, straightforward, not too terribly expensive, and solved a long-standing and annoying problem. For engineers it doesnt get any better than that.

One-third of Dutch households are using some sort of smart home technology, to regulate their heating, monitor security and even switch off lights.
Intelligent robot vacuums that clean the floor, your children telling the bathroom light to turn itself off and checking who is ringing your doorbell while you are having drinks with the neighbours smart home technology is seeping into many aspects of our lives.
Yet despite the advantages smart home technology offers, research published in September shows that even though almost two-thirds of Europeans are interested in installing some sort of smart system in their homes, most have not yet gone down that road.
The research was published by the Smart Home League, an alliance of companies involved with smart home technology. It showed that although only 11% of European homes currently employ some form of smart technology, that total is set to accelerate as more devices are developed and more consumers become aware of the advantages they bring.
Climate
German intelligent home climate management system Tado for example, says it want to demonstrate how technology can help people make their lives easier with technology, while saving energy and cutting energy bills at the same time.
Energy saving is a hot topic in the Netherlands and the Dutch can count themselves among the early adopters when it comes to smart homes. Research by the Smart Home Monitor early this year showed over one third of Dutch households already have some form of smart home technology, far outstripping the European average.
Energy and climate control systems to help residents to reduce energy consumption and save money were top of the popularity list, followed closely by followed by lighting and home security.
Consumers have a wide choice of devices and suppliers to choose from. Among the dozens of security systems on offer, French firm Netatmo has smart alarm systems using cameras, movement sensors and smoke alarms so you can protect your home both inside and out. The company also produces air quality monitors and heating system regulators. The aim, the company says, is to help users create a safer, healthier and more comfortable home.
Light switches
While the advantages of a complete home security system are easy to see, some of the more minor services offered by smart home technology such as light switch control might seem a waste of time.
However the Smart Home League research showed that two-third of Europeans are bothered by simple household tasks such as turning down the heating and searching for keys which can be easily solved using smart home technology.
The smart home is currently moving from early to mass adoptions, but to drive that forward, companies much make sure devices are accessible, affordable and easy to use, the League says. Smart speakers like Amazon Echo and Google Home have accelerated smart home adoption, because they are simple to set up and easy to integrate into every day routines.
Cost effective
In this way, the smart home can support consumers by making their homes safer, more comfortable, more energy efficient and increasingly cost effective.
The alliance survey also showed that 37% of people plan to buy a smart home product within the next year and that 68% of people who already have one such product are ready to buy another. This, the compilers say, suggests people who use them are aware of both the value and the benefits.
People want a smart home that provides them with a positive experience, says Dave Ward, European product director at Smart Home Alliance member Ring in a press release. They want to see a true benefit, something that solves an issue, rather than simply adding technology to their home.

SINGAPORE - A tender to install, operate and manage 6,000 digital displays screens in lifts and lobbies in Housing Board blocks has been won by Target Media Culcreative (TMCC).
The panels will be built by June 2020 and allow more residents to receive information and news from the screens, in line with the Republic's Smart Nation drive to leverage digital technologies.
The project will be fully funded by TMCC - a joint venture between Singapore Press Holdings and Focus Media China - which beat out three vendors to win the tender.
Most of the panels will be installed at lift lobbies on the ground floor, with others inside residential lifts.
The content broadcast on the screens will range from local notices on activities in the estate to nationwide updates on emergencies and public health advisories.
In its call for tender in October this year, HDB said that commercial advertisements could also be displayed, but it will be capped at 30 per cent of the total screen time.
There are currently about 8,700 such panels installed at common areas in HDB blocks.
TMCC operates 8,000 screens across seven of the 16 townships in Singapore - Choa Chu Kang, Tanjong Pagar, West Coast, Jurong-Clementi, Sembawang, Tampines and East Coast-Fengshan.
International brands such as McDonald's, Mitsubishi and Redoxon, as well as government agencies such as the Ministry of Communications and Information and Ministry of Manpower have broadcast content on these screens, TMCC said.
Apart from investing in the hardware and software of the panels, the firm will also pay a temporary occupational licence fee to HDB, which is similar to the current arrangement it has with town councils.
Mr Jeff Liu, chief executive of TMCC, said: "In our past experience of building 8,000 screens, we understand how the digital display panels can bring vibrancy and relevance to HDB dwellers.
"In sync with the Singapore's government push for digitalisation, our smart digital display panels serve as an innovative channel and green initiative for the majority of Singaporeans to receive timely and relevant information."

Written by Hina Rohtaki | Chandigarh | Published: December 16, 2019 10:38:22 am The vendors site in Sector 15, Chandigarh. (Express photo: Kamleshwar Singh)
IN ANOTHER glaring example of splurging public money, the Chandigarh civic body will be providing flooring afresh on a site meant for street vendors which was refurbished in January this year with neatly layered paver blocks, completely intact. The new flooring at this vendors site which is one of the largest among all vending sites in Sector 15 will be done at a cost of Rs 37.49 lakh.
According to the estimate prepared by the engineering wing, accessed by Chandigarh Newsline, of this Rs 37.49 lakh, around Rs 1 lakh would be spent on dismantling the concrete paver blocks and stacking the existing ones. Providing and laying cement concrete of specific grade excluding the cost of shuttering will be done at a cost of Rs 19,48,875 and another part of it will be done at a cost of Rs 8,66,658. The railing would be installed at a cost of Rs 3.02 lakh.
When contacted, Chief Engineer Shailender Singh said that existing pavers are not to be dismantled and an approach road needs to be made. However, when told that it was in the documents of estimates prepared by the engineering wing that the existing ones will be dismantled and nowhere in all the 17 points of the estimate it was mentioned that any approach road will be made, he said he would check with the executive engineer concerned.
Former councillor and BJP leader Saurabh Joshi said that this expenditure was not justified as the site was refurbished in January this year and pavers were completely intact. It is surprising that not a single paver block is broken. And why do they want to make it concrete again by splurging public money? Just this January, they made the area concrete, Joshi said.
Joshi also raised a question as to when the change in land use was done as it was a green belt earlier. Has a proper procedure been followed when the change in land use was done because I was told by the department of urban planning that the CLU cant be done? So now, how did they convert the green belt into this land? And did they call in public suggestions and objections for this? Joshi asked.
Surinder Sharma, president of the Residents Welfare Association of Sector 15, said that a vigilance inquiry should be ordered into the fresh expenditure that is being incurred at the site. They have made it a money-minting thing. Everything is in a perfect condition. Moreover, they should focus more on the fact that the choice of this site is faulty. Who will provide security to the girls who are in the hostel adjacent to the site? he asked.
The site was recently revamped for as many as 936 vendors. Residents have already been raising questions on the choice of the site saying that there is a girls hostel next to it and it will become a hub of anti-social elements.
