I can't tell yoiu about the modifications, but the article on them appeared  
in Fine Tunings Proceedings. I think it was the first issue.

A "Mixer  Trimmer" potentiometer and new mounting plate is positioned on
the front  panel where the clock would be. And there is a small circuit
board mounted  underneath the chassis with some components, including
what looks like a  varactor diode.
Its all been done very well, and the mixer pot seems to add  a few S
units to a signal, and acts similar to the Antenna trimmer  control.

Is anyone on the list familiar with these mods, or a schematic  of the
circuits. I seem to remember a SWL publication that mentioned  something
about this mod. in the past. Thanks very much.
