[ForSale-Swap] FS: Frequency Synthesizer fro Drake R-4 Series Receivers

[Bob Stein]

This frequency synthesizer for the Drake R-4 series receivers was
designed and built by me and was published in the August 1972 issue of
"ham radio" magazine.  The synthesizer provides complete coverage
from 500 kHz to 30 MHz.  When the Drake receiver is used as the
controlling VFO in transceive mode, full operation is possible from
1.5 to 30 MHz, including the WARC bands.  I will supply an original
issue of the magazine (torn cover), as well as schematics of all the
circuits which improved performance but were never published.

Best offer over $275.  Buyer pays shipping.
