Curt -
I haven't seen an answer yet. Mine does the same thing, even a couple of kHz
one way or the other.
I use the R-7, so hardly ever use the RV-7 and hadn't noticed it before. I suspect it has something
to do with the GATE timing of the DR-7 counter board. I don't 'think' the GATE is

Just tried it with the R-7 in transceive mode and does the same thing. Still think it's the counter

counts a real RF signal in the radio. At the instant the radio
Thanks Garey and Jim:

few hours. Monitoring shows no sign af any glitch on the real signal
and I cannot hear any blip in rx either. Interesting that it is
assymetric...ie does not jump when going from Rx to Tx but does

investigation found nothing wrong with any of the oscillators.

When returning to rx after transmitting, the frequency display on the
TR7 jumps in a momentary blip up between 200 and 800 Hz. It
