[R-1051] OFF FREQ

[tgrieco at optonline.net]

Mike,
The highlighted area is where I am stuck now. I have no signal generator-any other way?
 
Getting it back in tune is relatively easy: set the knobs up for a given
freq, set a siggen to that freq and inject it into the RX, loosen the idler 
and turn the correct gear on the underside of the RX until the siggen
comes in. Once you've got everything set right, cinch down that idler. 

Let us know how this comes out.
