I briefly went by to look at then tonight (Saturday). It looked like
someone had already tried to get them working. The TM-2520A didn't have any
audio as I assume someone had already determined.. I found out that tone
squelch was set and I think I turned it off. Still no audio though. One of
them had been opened up. I didn't mess with it.
I will get my dummy load and power meter and head over tomorrow. I I will
get the manuals from the web and (if I can find someone to let me in) see
if I can get a squeak out of something.
