Thanks Ralph, I haven't looked inside the frequency module yet to 
confirm but it's obvious this is what someone did to this one.  To my 
surprise I was able to hear QSOs on 75 and 40 meters so I figured it was 
more likely the carrier osc. had been shifted than a different filter 
installed.  But the guy didn't do the mod to the synthesizer, which is 
why the khz knob is marked "-3".   If you have the details on this, I'd 
be interested in taking a look.

I don't like modifying gear, but in this case it does make the radio a 
lot more useful.
