Here's a photo of the
20-M CW/SSB transceiver's AGC and audio board,
shown during construction and testing phases of
development. Yes, it's a quick "dead
bug" lash-up, but it works!
This view shows the
transceiver's receiver section, with RF amplifier
and front-end tuned circuit mounted atop the
shielded VFO assembly.
The multi-section variable
capacitor comprises part of the set's tuned
front-end preselector.
Here's the IF amplifier and BFO
board. The daughterboard at the upper right-hand
corner is a 4-pole Ten-Tec 2.1-kHz-wide 9-MHz
crystal filter. It was obtained new at a hamfest
for 50-cents.
