Etherkit releases CRX1: A new 40 meter receiver kit
<p>We are pleased to announce the release of Etherkit’s newest product, the <strong>CRX1</strong> receiver! </p>
<p>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. </p>
<p>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). </p>
<p>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!</p>
