It all started when we went up to replace a failing antenna, and a
mess of adaptors..
The antenna is a GP-9 that had some water in it, and was slowly
turning into a dummy load. I'd had the UHF system running into it
through the band coupler with the VHF system, but I could see the
output on both systems getting weaker, and I was worried about SWR
into the UHF amp, so I commanded that system offline a couple weeks
ago.
Then I got the flu, and the weather was nasty..
Friday, with clearing weather and head, we went up, thinking that
after we replaced the antenna and adaptor mess, we could put the uhf
system online.
Antenna replacement went well, and then I replaced the adaptor mess
with the 6" cable I made from BNC male to N male, replacing a handful
of adaptors that I'd kludged into the system originally, to make the
distance and two 90 degree bends that were required. This is the
adaptor mess that was getting hot.
Now the new cable is in place, and that power that was getting turned
into heat is getting delivered to the cans. But, something smells
funny, and the interconnect cables between the cans are noticably
warm.
I need to go back up there, and pull the amp and cans, and see what's
going on..
I'm just kind of disgusted.
These are Wacoms, I don't have the exact model number in front of me,
but if I remember right, they were rated for 150W or thereabouts. I
had tuned them before, and everything was looking good, but it
appears that when the adaptor chain wasn't in the picture sucking up
power, I crossed some threshold and damaged the cans.
Anyone seen something like this? What are my prospects of repairing
these cans?
