ARLA/CLUSTER: Receptor de 40m em kit

[João Costa > CT1FBF]

Etherkit releases CRX1: A new 40 meter receiver kit

We are pleased to announce the release of Etherkit’s newest product, the *
CRX1* receiver!

The CRX1 is a simple VXO-tuned superheterodyne receiver for the 40 meter
band, with tuning centered around the popular QRP watering hole frequency
of 7.030 MHz.

It is entirely constructed from surface mount devices in the easy-to-build
0805 (US) size for passive components and SOT-23 class semiconductors. The
PCB is large and single-sided, which provides for uncramped construction
and makes the CRX1 an ideal warm-up kit for the CC1 QRP transceiver (coming
soon).

The CRX1 is not just meant to be a novelty to be tossed aside after
construction. All of the support circuitry for muting, T/R, and sidetone is
included, so it can be paired with virtually any transmitter which uses
grounded keying. There is also a port for an external VFO to enable further
user experimentation. All controls and connectors are included with this
kit, so you just need to supply an enclosure and a few knobs to finish the
job!
