The
ZZRX-40
is a 40-meter CW or SSB receiver kit. It can be operated in crystal
mode or
can be tuned (with a fine touch) over a wider range of frequencies, by
configuring
jumpers to use an internal VFO. The internal tuning control is a
varactor.
The kit, which includes the bright red enclosure shown in the photo was enjoyable and instructive to build.
