Heathkit HX-11 Tune-Up with SDR Receiver #hamradio #qrp #vintagegear #boatanchor #heathkit

This was my fully restored Heathkit HX-11. It was an upgrade from the DX-20 as it had a built-in source for antenna changeover. I added an opto-coupler to the keying circuit to remove high voltage from the Morse code key. It’s called the Keyall+ and can be found online at Jackson Harbor Press.

The SDR is the RSPduo. I’m running SDR Console software because it includes a mute system that prevents front end problems when transmitting. The transmitter and receiver are separated and sequenced using an MFJ 1708 RF Antenna Switch. It is activated by RF power from the transmitter so it is super easy to employ.
