[1000mp] Humm

[KB9GKC at aol.com]

Hello,
 
Try disconnecting your plugs for your digital modes and then see if the  
humm goes away on transmit, bet it does!  Ground loops anyone??

I  was trying my new to me rig this morning on SSB and had complaints
about a  hum on the signal. I turned on the monitor and sure
enough, sounded like an  AC humm. It is not present in digital
modes. I had found the grounding  suggestion for mike connectors
in the archives and had done that. It will  make the humm with
no mike connected. The FT1000MP is grounded well to  my
station ground.

Any  suggestions?

thanks,
