By any chance do you use an amplified DSP speaker?
I use one mobile with my FT857D and if I have it set too high on the filtering I get this issue at times. I just turn down the filtering and it goes away for me.
Only a try at a suggestion.

Jim, Well if you are connecting straight to the antenna with no tuner or switch/adapters in-line and you have done the master re-set/relay cleaning procedure with no positive results I am at a loss as to what the problem could be or what could have caused it in both radios. If no one on here comes up with a fix I would say contact Yaesu and maybe send one in to be checked out by them but whatever the fix I know all of use 857 owners will be more than interested in the cause and fix. Good luck 73's Troy ke4ska.?
