[Kenwood] TS-930S Alignment Question

[John Meade]

I have a TS-930S/AT that I bought new in 1985.  It is still a great CW rig 
with excellent QSK.  I added the Piexx digital board and I am enjoying the 
extra memories and PC interface as well as the other features.

I have two Fox-Tango 400Hz filters in the rig.  They are really effective 
filters.  However, something has drifted a bit over the years.  The passband 
of the sharp filters is slightly off from the pitch of the side tone. When I 
tune in a station with the sharp filters, the pitch of the signal is lower 
than that of the sidetone by maybe 200 Hz. If I zero beat the incoming 
signal to the sidetone, the signal is just out of the sharp filter's 
passband.

I am wondering of there is an adjustment to bring the sidetone down in 
frequency without moving the pitch of the received signal.  (Or, moving the 
pitch of the received signal without moving the sidetone frequency).

The CW Pitch adjustment seems to move both of the tones together. So does 
the CAR3 adjustment. I want to make sure that I am still zero beat if I 
match the incoming received signal's tone to that of the sidetone.

Thanks and 73,
