[Hallicrafters] HT-30 problem not fixed-new clue

[Robert Sauvan]

Decided to check the coax swap a bit more thorough.Put the rig on the 
air for a bit and all was good for the time. So, decided to swap swr 
meters to see if they were reading the same as the last one inline. I 
noticed when I was taking off the cable from the meter I saw some 
sparking between the coax fitting and the fitting on the meter as I was 
pulling them apart. The sparking was on the ground side of the PL259 
before the center pin came out of the SO239. This was all done while the 
radio was turned on in warmup mode. I put another meter on and I had my 
warmup to standby transmit problem back. Looks as though it is a bit 
intermittent but that sparking I saw should be a clue as to what may be 
occurring with the meters and the radio. I will admit, I have seen this 
sparking before and wondered but disregarded it at the time. The cable I 
saw it on was the antenna side of the meter. I did not check the 
transmitter to meter input yet. Now I'm thinking it is a very big hint. 
I do have the radio grounded. The saga continues.
