The FM band is about to get more crowded, courtesy of the legislative branch of the US government. I have been mixed on LPFM based on my own technical experiences. That being said, the FCC seems hell-bent on shoe-horning every possible signal into the FM band, so why not? It certainly won’t be any worse than IBOC or the ever-growing crop of translators. LPFM could possibly bring back local radio to some markets, depending on who gets the licenses and how they are acted on. A local school district around here picked up an LPFM license on the last go around. During the double blizzard of February 2010, they filled the shoes of the two former local stations, which have become remote-controlled repeater stations for a city 35 miles away, so there is a glimmer of possibility.
According to HR 6533, the original channel spacings (elimination of the 3rd adjacent channel protections) in MM Docket No. 99-25 are to be implemented. Additionally, LPFM stations are on the same footing as translators and FM booster stations, which is a slight change from LPFM 1.1
I’d expect to see an NPRM from the FCC rather quickly, as the bill is pretty specific. It may be interesting to see how possible frequencies are identified for LPFM service.
Sounds like some dire prediction, but no, actually it is a good radio show heard on Shortwave, WWCR-2 to be precise. The show, at least during the weeks that I heard it, consisted of blues and other music that you likely won’t hear anywhere else. Allan Gray, the host, also often interviews musicians and other persons of note. I stumbled on this show a few weeks ago while listening to 12,160 KHz on Saturday afternoon. WWCR is touted as “World Wide Christian Radio” and there are many religious shows to be sure. They also air several secular programs like World of Radio, Golden Age of Radio, DX Partyline and Ask WWCR and Info Wars, and others.

From reading their schedule, Last Radio Playing can be heard on WWCR-2 Tuesdays at 5 pm est (5,070 KHz), Saturdays and Sundays at 3 pm EST (12,160 KHz), and on WWCR-3 at 8 pm (4,840 KHz). WWRC is located in Nashville, TN. They have four Continental 418 HF transmitters with a carrier power of 100 KW each. WWCR-2 uses an azimuth of 85 degrees true and WWCR-3 uses an azimuth of 40 degrees true, both into Rhombic antennas with 14 dBi gain.
Today the show consisted of Christmas Music, which on the AM wide band receiver, sounded pretty good. Anyway, if you are so inclined, tune in and take a listen.
I found this in one of the file cabinets at the transmitter site. It was apparently used as scrap paper because there is what looks like connection information for a remote control system scrawled on the back. I thought it was interesting as it shows a 6 a.m. sign-on and the type of programming, source, and exact times each element ran. For Origins, YN = Yankee Network, BPT = Local Studio (Bridgeport), and NBC = NBC. Program logs for later years (1943) show the Alarm Clock Salute was received via FM from W43B (Paxon, MA) on 49.3 MHz.
Sign-off was at midnight. It must have been cold in that little house out on the island in February.
Anyway, I’ll save these in my radio station history files.
The WICC transmitter site, Pleasure Beach in Bridgeport, has been cut off from normal access since the bridge to the island burned in 1996. Since that time, access has been by boat with a 0.93-mile walk from the dock to the transmitter building.
Last summer, LVI Construction, under contract from the Town of Stratford, put in a temporary road and began removing the burned out cottages. While that road is in place, the radio station has been able to access the site and get many important things accomplished. These include:
Removing several decades worth of stored crap, garbage, obsolete and unused equipment
Repair the electrical service to the building
Replace the generator transfer switch
Repair the Sonitrol building alarm
Replace the old Onan Generator
Have the power company replace the 3-phase circuit from the point where the underwater cables come ashore to the transmitter building.
All of these projects should greatly improve the reliability of the station. This should make Bill, happy, who appears to have a WICC chip implanted in his brain because every time the carrier is interrupted he posts about it on the radio-info.com website.
The biggest issue with the site was the utility feed from the shore to the transmitter building. The original circuit was installed in 1936 when the station moved to the island. It was old and the poles were all rotting and had horizontal cross arms. Ospreys especially liked the horizontal cross arms as they made good nesting spots. That is, until the nest shorts out one of the phases catches on fire and burns the top of the pole off. This has happened several times over the years causing many hours of off-air time.
WICC new utility service
United Illuminating, the local utility company, was very cooperative and installed new utility poles, wires, breakers, and transformers, this time with a vertical phase arrangement, which should keep the Ospreys off of them. Additionally, the cottage removal project included installing Osprey nesting poles.
Pleasure beach cottages removed
With almost all of the cottages now removed, the area looks much better than before. Actually, it should be a nice nature preserve, and hopefully, the absence of the buildings might reduce the number of vandals in the area. The work is almost done, so the road is about to be taken up. This means we need to wrap up the work out there, so the final push is on.
WICC transmitter building
In the last three weeks, 10 truckloads of junk have been hauled out of the transmitter building and generator shack. Over 1,500 pounds of scrap steel, 640 pounds of insulated wire, 2,000 pounds of particle board furniture, old t-shirts, and hats (something called “Taste of Bridgeport” which, if anyone knows what that was let me know), old propane tanks, batteries, etc. We also managed to fix the fence and gate in front of the building and cut down the overgrown yew bushes and bittersweet vines.
Transfer Switch
The old Kolher transfer switch was also an issue. There was no place to mount a new switch inside and mounting one outside is out of the question, so the guts from the Kohler switch were removed and replaced with an ASCO unit. This was done in the summer of 2009. The breaker on the right side is the main service disconnect for the building, which was installed in September.
Onan 12 KW 12JC 4R air cooled generator, removed from service
Today, it was time to replace the Onan propane generator. The old generator is an Onan 12JC-4R air-cooled propane unit which was installed on April 4, 1969, at a cost of $1,545.00. For many years, this unit gave reliable service, but it has many, many hours on it and it lacks the fault/self-control circuits needed for remote (read desolate) operation. Several times over the last few years, the generator would run out of gas or the propane tank would freeze up and the starter would crank until it burned out.
It was cold out on the island, with temperatures in the twenties and a bitter west wind blowing right into the generator shack. All of this conspired to make working conditions difficult. Wind chill readings were in the single digits all day long, and in spite of long johns and extra layers, by 3 pm I was shivering and even several hours after coming inside, I still felt cold.
Using tractor to move new generator
The new generator is a Cummins/Onan 20GGMA which is rated for 20 KW. We used a John Deere bucket tractor to move the generator from the flatbed truck to the generator building, and then push it inside. The old generator wiring to the transfer switch was reused, but a piece of flex was used to connect to the generator instead of the solid conduit. The building fan was also wired up so that it would run whenever the generator was running.
The generator load with all possible things switched on and the transmitter running at full power is about 12,000 watts, but this would mean the air conditioner and tower lights were on during the daytime. More likely, the transmitter will be at low power when the tower lights are on and the AC will be intermittent on/off at night. At full load, this generator uses slightly less than 2 gallons of propane per hour. At half load, I’d estimate that to be 1.4 or so gallons.
Cummins Onan generator in new home100 pound propane gas tanks
HOCON gas came out and connected six 100-pound propane tanks in series, which should prevent tank icing. Propane weighs about 4.11 pounds per gallon, therefore the fuel supply should last about 100 hours, or 4.5 days, give or take. Why 100-pound tanks? Because we will have to shuffle them back and forth between the dock and the generator shed, a journey of about one mile, in a cart. Anything larger would be impossible to deal with. Even so, refilling the propane will be a 2 person job and will likely take all day.
