Update- 17 Feb 2010, I fabricated a power plug onto a pigtail and powered up the shelter. I
went through everything but could not get the GRC-106 radio to power up. I checked the fuse and found it blown. I replaced
it with the spare that is contained on the radio. That blew too. So...the radio has a short of some kind in it. I have
a friend that knows about these old things that can help me work on it in a few weeks. So for now the door is locked and Im
moving on to other projects.
Update- 1 March 2010, I was able to make a connection with a fellow
that let me salvage cables out of a S-250 shelter that was a GRC-142 TTY rig that he is using for storage. I was able to get
the cables I am missing for the front TTY and the right side TTY, but not the TT-76 that goes on the left. At least
now I know what they look like so I can most likely strectch out whats left of that cable for the left TT-76 and make the
Update-16 March 2010, I
was able to locate the source of the short in the GRC-106 RT-834, it was a 40v 120MFD capacitor power filter shorting through
to ground. I dissassembled the RT and traced it down, removed it and replaced it with the closest available capacitor
made today, a 50v 100MFD.
I also just aquired a bunch of RTs and another amp. In testing, one
RT-662 blows fuses and needs repair, one RT-834 powers up and recives fine, and the other RT-834 recives ok for a while but
the RF and Audio drop off over time or when the freq is changed. That needs more looking into. The power Amp seems
to be DOA. The Test Meter doesnt move on power up. Im looking into getting more help on that.
Update-18 March 2010, I moved the
shelter from my f-150 to the generator trailer.
Update- 28 April,
2010, I picked up the teletypes TT-76 and TT-98 at the Tower Park meet. I have set them in place but
not serviced them yet or hooked them up.
