Water and transmitters do not mix

This incident happened a few years ago.  I thought I had lost the pictures of the disaster, but I found them this morning on my thumb drive. Hooray!  This occurred one morning just before Christmas after the area received a snow/ice/rain storm.  The gutters on the old ATT long lines building clogged with ice and the water on the roof built up.  Unfortunately, the transmitter was installed directly below a disused exhaust stack for the former backup generators.

I received the off air call from the morning show while I was driving to the office.  I diverted and went to the transmitter site and found water pouring into the top of the main transmitter.

Thus, water ran down directly into the top of the QEI FMQ-3500 transmitter (transmitter was upgraded to 6 KW). Unfortunately, high voltage and dirty stack water do not mix. The combination of sooty, iron laden water and the B+ damaged much of the transmitter circuits beyond repair.  The main transmitter is on the right, the backup transmitter is on the left.

I inspected the backup transmitter, also a QEI FMQ-3500, and it seemed to me that no water made it into the unit.  I rigged the tarp to ensure that none did, which was a very pleasing bit of work, what with the cold, smelly, dirty diesel water dripping on my head and running down my neck and back.

The 1 5/8 coax switch was also damaged:

Fortunately, the backup transmitter ran, although I pressed the plate on button with a dry wooden stick while standing on a dry, non-conducting ladder.   Even so, I still felt a little trepidation holding that stick.

It took almost a year, but finally the insurance company for the building owner came through, and a new Nautel V-7.5 transmitter was installed.  I believe this is the last V transmitter Nautel made.  We moved the transmitter location across the room, not under the old generator stacks.  We also removed the generator stacks and patched up the roof with hydraulic cement and roofing tar.  By the way, that yellow color should look familiar to anyone who ever worked inside of a Bell Telephone System building.

    If pro bass fisherman Bill dance were in your shoes and seen that,I bet he would have been saying “Oh goodnight,look here,….oh oh oh oh me!” That had to have been a hell of a sight when you walked in on that,Paul! At least insurance took care of it and the station received a new transmitter.

  • I remember you telling me about this one. Wow that was bad.
    Glad to see it all got straightened out.

    Is the backup QEI still there or was that decommissioned too?

    @Dewey, I don’t recall exactly what I said when I first came into the room, it may have included a swear word.

    @Mike, the backup QEI transmitter is still there, but not connected to anything. The Nautel is reliable enough that it is not needed.

    Do you know the name of the AT&T site; or have a ASR or other locator?

    Does the broadcast station use the Long-Lines tower?

  • Paul Thurst

    ATT site name was, I think, Hallihan Hill. American tower site number 88128, which is down as a wireless site, although this is a broadcast installation. Yes, the broadcast antenna is on top of the taller of the two towers.

    Not my idea of fun. What a transmitter site call to have to attend to. Good news out of it, ya have a nice shiny new Nautel transmitter. A brand I swear by, not at. Sooty, iron laden Water and High B plus voltages equal fried transmitter. Nautels usually just run and run, keep her clean and cool and feed her well regulated AC and 50j0 and enjoy. Boringly reliable.
