Re: IF shift

[VR2BrettGraham]

No, this is not an LDE - I simply missed sending it
originally.

In the meantime, I would have sworn the TS-820 my
father had did have an IF shift knob, turning that knob
caused it to behave like the radio had IF shift & this IF
shift functionality worked on all bands.

As they say, live & learn.  Will I still be alive & be able
to understand what from today I also have gotten all
wrong when 25 years from now somebody similarly
enlightens me to my obliviousness?  ;^)

Brett,

Yes, the Kenwood TS-820 was a single conversion transceiver that
implemented IF shift.

To have IF shift in a single conversion receiver it is necessary to
change both the VFO and BFO together in synch (and in the proper
direction).  I believe it could have been done in the K2 microprocessor
with enough memory space to accomplish that feat.  The K2 microprocessor
has been short on available memory space for its entire lifetime.
