Product Information
Specification

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!
