#355: Radio Review: FX-4C SDR QRP Transceiver | Review of features and operating controls @w2aew

Uploaded June 2022 | Updated September 2026, 2 weeks ago

Review of the features and operating controls of the FX-4C - a great little SDR Transceiver designed by BG2FX. NOTE that I mis-stated the transmit range in the video. This rig does NOT transmit on the 6m band. It transmits only on the 80, 60, 40, 30, 20, 17, 15, 12 and 10m bands. The homepage and purchase link can be found here:
