[ICOM] 751A

Or you have a decoupling cap on the DC supply to the audio section, or
the PLL section. 

I don't recall either of mine doing that. Try the easy stuff first as
Gary suggests.

Eddy,

I think thats the LPL Loop resetting. I don't remember if it is so 
pronounced so you can hear it but I had that question a few times 
while I worked at Icom.
Might be the loop is on the edge and resetting the loop voltage might 
take care of the issue.
