[Hallicrafters] HT-30 and SWR meters

[Rsauvan]

Thanks for the info Roger,
But, I have tried all of the suggestions you through at me. It shows 
output on any band in any mode. I have swapped cables. It does it with 
any of the swr meters I have. Almost acts as if they are shorting 
something and putting the thing into transmit. I will have to put the 
rig apart and look at the coax connector to see if I think anything 
looks weird. Will let you know.

Thanks-Bob
