Hello everyone,
I have a lafayette SSB-140 base station. The chassis is a PTBM058COX which is also similar to PTBM048. I just got through an alignment with this thing, all went well, except for the fact that when I hook this thing up directly to my antenna, it gives me a carrier on sideband. A fairly big one too. The weird thing is that when I hook up my SWR/Power meter, the issue does not occur. There is no problem with the antenna as far as I can tell, SWR is slightly over 1:1 and I see no problem with the coax, it's almost brand new. The thing just does not like being hooked up directly to the antenna, with SWR meter inline, all is fine. The balanced modulator isn't the issue either, tweaking it doesn't help.
Anyone here have any idea what could be causing this?
