[Lowfer] Rubber crystal

[Don Moth]

Hi Mitch
I see the schematic for Don. I have the 8th edition of Kens Scrap Book with
the same. Have read it cover to cover several times. a wealth of info. I
don't understand the size of the coil "1-12", guess I am getting old at
only 75, hi hi.
Guess I will have to hook one of the radios to the computer so I can copy
you guys on QRSS. 

Don
