[Milsurplus] [ARC5] Navy GP-7 Transmitter Connectors Available

[John J Mccarty]

I also have had my GP-7 on the air via the generator from a TBW. The generator
has sprung a pretty good oil leak and is on my winter "to-do" list. Used the rig
paired with an ARB to check into some of the AM nets here in the Midwest. One of
the AMer's did tell me he checked my signal on his scope and it appeared to have
"asymmetrical" modulation, which I took to mean that one side band was stronger
than the other. I put it down to poor tuning a grid modulated transmitter on my
part.


73 and Merry Christmas
