Can anyone tell me if their RV7 shows the following symptom?

When you trip the TX relay (either with PTT or VOX) the TR7 frequency 
display jumps in frequency.  It seems to always be up in frequency and 
anywhere from 200 to 700 hertz.  It then very quicky returns to the 
frequency I am dialed to.  My internal PTO does not seem to show this 
symptom.


I can not see any variance in the voltages on the RV7.  I had to use an 
FET analog meter because the o-scope is playing dead :-(


Maybe the voltage change is fast enough that the damping on my FET VOM is 
missing it?  I do not have the RIT on.


TNX es 73,

As an addendum, I've experienced such problems on several rigs due to a 
ground connection that was intermittant, going high resistance, etc.
