It has been a year and a half since the tower collapse in North Adams, Massachusetts. Since that time, WUPE-FM (Gamma Broadcasting), WNNI and W266AW (New England Public Radio) have been operating with STAs at lower than licensed power. We have completed the installation of the combined antenna, filters and combiners and now all stations are back to full power. Here are a few pictures of the transmitter room:
WUPE-FM (left hand rack) is using a Crown FM-2000 transmitter, loafing along at 1,060 watts. WNNI (right hand rack) is using a Gates Air Flexiva 2 running at 1,650 watts. Those stations are combined with a Shively Combiner:
We are still doing some grounding and neatening work behind the racks:
The Shively versa tune antennas that were mounted to the wooden utility pole as emergency antennas will be retained as backup antennas for both stations.
We share the room with Access Plus, which is a wireless internet service provider in western Massachusetts. There stuff is in the open frame racks to the right of WNNI.
TL;DR: Tower collaspes, facility is rebuilt better than before.
So, I was working at one of our FM clients in Albany when I decided I had a few moments of spare time, I could neaten up the remote control rack. I opened the rack door and was staring intently at the remote control interface panel, when out of the corner of my eye, I saw something move.
Now, the top of the rack is a little bit dark and I was not sure what I was looking at. At first I though somebody had stuffed a rag in the top of the rack. But, I could not figure out why anyone would do such a thing. Then I thought it was some cardboard. I almost reached up and grabbed it, but something was amiss. Then I saw the tough flick out and smell the air:
At this point, I think I may have said something like “Oh, shit!” and took several steps back. Those colors and pattern have two possibilities; Copperhead or Grey ratsnake. Since I could not really get a good look at its head, I could not tell which it was. I went and got a work light to see better with.
A copperhead is a pit viper, which has a triangular shaped head and a small indentation or pit under each eye. This snake has neither, so it is fairly harmless. Actually, the ratsnakes are beneficial because they eat the mice and other pests around the transmitter building. There are several versions of these in the northeast, including a black ratsnake which happens to look just like a piece of 7/8 coax laying across the pathway to the door, until it moves that is…
This species can get to be about 6 feet long (1.8 meters) and the larger ones can draw blood when they bite. Even though he looked to be on the small side (approximately 30 inches or 76 cm), I decided that discretion is the better part of valor, closed the door on the rack and did something else for a while.
Whilst working in the generator room at WFLY, I found this bit of treasure stashed on an overhead shelf:
That is a very old FM broadcast antenna from 1947-48. It must have been intended as a spare antenna in case the main antenna had a problem. It was never needed, so it remains in its original shipping crate. I would think that these were rather well made, since the original main antenna was in service from 1948 until 1970 or so, when it was replaced with a Shively 6710.
The entire antenna is intact including the interbay lines, power divider T’s and tuning section. Of course, it is of little use to the radio station today, as it is horizontally polarized. Perhaps some museum somewhere? I don’t know, it would be kind of neat to put it all together and use it as an exhibit.
Update and bump: I hate to rehash old stuff, but I added quite a bit of information to this post, including .pdfs of all the Barbeau letters, blue prints, etc. I’ve been doing quite a bit of work at this site lately, so it is in the front of my mind. I have also been reading about the Rural Radio Network, which covered western and central New York.
Several years ago, I rescued a old filing cabinet that was being trashed. This particular file cabinet was moved to a transmitter site during the great radio consolidation of the late 90’s and early 00’s. In it, I discovered a treasure trove of early documents about two radio stations from the Albany NY area. I thought it would be interesting to document the building of one of the early FM stations in Albany, WFLY.
Albany is the capital of New York. There were several early (prior to 1940) AM radio stations in the Albany area:
WGY previously owned by General Electric in Schenectady, signed on in 1922
General Electric, who worked closely with RCA in radio development and experimentation, was working on TV in 1928 and FM radio in 1938/39. There were also several early (prior to 1950) FM stations in the area:
GE owned W2XOY on 48.5 MHz (circa 1939), later W85A, WGFM, and WRVE 99.5 MHz.
Independently owned W47A on 44.7 MHz (circa 1940), later WBCA 101.1 MHz, now gone.
WTRY owned WTRI-FM on 102.7 MHz (circa 1947), off air by 1954. 102.7 frequency later used by WEQX in Manchester, VT
These stations operated from transmitter sites in the Helderberg escarpment on land that was formerly owned by the Albany Bible Institute. It is interesting to note that two of the four FM stations did not make it past 1955. In 1967, WTRY did make a second attempt at FM, launching WDKC on 106.5 MHz, which is today known as WPYX.
It would appear the Troy Record initially applied for an FM broadcasting license in late 1946. The paper trail that I have starts in early 1947, when the station hired consulting engineer Ernest Barbeau of Schenectady to oversee the construction process for the studios and transmitter site. Ernest Barbeau, in an introductory letter to Frank York, publisher of the Troy Record, notes himself as a former GE engineer and assistant to W.R.G. Baker, General Electric’s television pioneer. At the time, it was already understood the height means almost everything in FM broadcasting. There are several letters dealing with land acquisition and transmitter building construction.
Below is a chart of all the various Barbeau letters written in 1947. I have scanned and uploaded .pdf files of each letter, sorted by date (the entire archive is available here (6.5 Mb .zip)):
This is a treasure trove of information on how this, and perhaps other early FM and TV stations went about finding land and building remote transmitter sites. Remember that before this, AM transmitters could be placed in any convenient location with enough space for the tower and ground system. The line of sight nature of VHF required high locations, which in the Northeastern US, means prominent hills or mountains. Sadly, this paper trail goes away in 1948.
Here are some of the highlights found in the letters above:
Washington DC consulting engineer for the project is John Barrons, who at one point suggests a different transmitter location closer to the city of Troy. Barbeau insists that the Helderberg location is best because the GE engineers chose it for their FM and TV experiments.
Negotiations with several land owners along the edge of the Helderberg escarpment are finally successful, with a 10 acre parcel of land purchased from Mr. La Grange, noted as being across Camp Pinnacle Road to the south of the WBCA transmitter and adjacent to the west of the GE parcel, cost $2,000. From this, I surmise the former W47A/WBCA site stood where the former WHMT/WVCR site stands today.
Land survey completed by Mr. J. Kempf of Albany.
The FCC application is completed with new transmitter location, antenna height and frequency of 92.5 MHz (this was changed to 92.3 MHz prior to sign on).
At one point, Barbeau tried to hire Walter Watson, an RPI architecture student, to draw up the studio floor plan, paying him $15.00. At first Watson agrees, then backs out of the deal. Frank York hires an architect to draw the studio floor plan and the transmitter site building plan.
Once the plot of land for the transmitter site is purchased, several different building locations and antenna configurations are discussed. It is noted that both WBCA’s and WGFM’s original antenna was mounted on a pole at ground level. The later station was moved to a makeshift tower.
WBCA management raises concern with the FCC about potential interference from the new station’s transmitter and potential STL, noted as an S-T link.
In September of 1947, Frank York expresses some concern with viability of project, Barbeau sends several “pep talk” letters saying that FM radio is the future of broadcasting.
The building site is chosen, land cleared, access road installed, work done by Orsini Brothers Construction from Altamont, clearing and road work cost $2,000.
The call letters WFLY are chosen, they are the initials of Frank Lloyd York.
An 80 foot Blaw-Knox self supporting tower is purchased and installed by Zane Construction, cost of tower is $1,700 installation was another $200.00.
Well is drilled by Stewart Brothers well drilling from Guilderland, cost of $5.90 per foot drilled, total cost unknown.
Transmitter building work began, building is noted as a two story, concrete block construction, work done by Orsini Brothers.
A GE BY-4-C four bay circularly horizontally polarized antenna and 3 1/2 inch Andrew transmission line is installed on tower.
Building construction progresses, telephone and electric service installed. Three phase electrical service cost $2,100 from New York Power and Light.
Studio site chosen in at the Troy Hotel in downtown Troy.
Living quarters constructed on second floor of building for full time transmitter engineer.
A GE BF-3A 3 KW FM transmitter purchased and shipped.
Building construction completed.
Transmitter installed and tested.
Telephone circuits between new studio installed and tested.
The transmitter site construction was finished in the spring of 1948. The studios were completed in late July of 1948 and the station signed on the air on August 18, 1948. This is the transmitter site that they ended up with. as it looks in 2015:
In addition to the construction, there was quite a bit difficulty from the WBCA management, who were concerned about possible interference. WBCA was part of the “Continental Network” and received most of it’s network programing via direct over the air relay from W2XMN/W31NY, 43.1 MHz, in Alpine, NJ. They complained to the FCC about potential interference on both their over air network relay (43.1 MHz) and the Studio to Transmitter Link from downtown Schenectady on 950 MHz. In the end, the FCC was unimpressed with these arguments and granted WFLY its operating license.
The transmitter building was made twice as large as needed because the Record had plans to launch a TV station and possibly a radio facsimile service. In addition to this, there were complete living quarters on the second floor which included a bathroom, shower, kitchen, bedroom and large living room area. This was in the era before remote controlling of transmitters was permitted by the FCC. It took a hardy soul to live at the remote transmitter site full time. Even today, it is far outside of town and can be difficult to get to in the winter time
These mountain top transmitter sites did not exist prior to the advent of TV and FM. The amount of planing and work went into launching this station is quite impressive. For the early FM radio stations, this type of effort and expense was probably typical.
