[1000mp] Humm

[Stu Ritter]

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,
