On that :"new" HW-101  I just got, there is a modification that places a 
"click on/click off" pushbutton and a red LED and a small knob just to 
the left of the meter.  It is a circuit on a GRP PC board that is 
mounted vertically on the right side of the VFO box.  It appears to take 
some signal off the grid of the VFO...or maybe its putting it on the 
grid of the VFO (pin 1).  Anyone know what this mod is for.  It appears 
to be very well done and were it a Phenolic board instead of GRP I would 
think it was stock Heathkit except for the lack of documentation and labels.
