Better Times at WICC transmitter site

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:

  • Replacing the vandal damaged top beacon on the South tower
  • 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 under water 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 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 like 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.

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.

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.

In the last three weeks, 10 truck loads 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, cut down the over grown 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 replace 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.

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 new.  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 feel cold.

The new generator is an Cummins/Onan 20GGMA which is rated for 20 KW.  We used a John Deere bucket tractor to move the generator from the flat bed truck to the generator building, 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 will run whenever the generator is 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.

100 pound propane gas tanks

HOCON gas came out and connected six 100 pound propane tanks in series, which should prevent tank icing.  Propane weights 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.
