WebJanuary 22, 2024 Leave a comment. As has been mentioned before, the transmit frequency stability of the QRP Labs QDX transceiver isn’t quite good enough for some of the narrow-band modes. It works fine for WSPR and FT8, but slower modes such as FST4W-300, -900, and -1800 require stability that the QDX’s internal TCXO just can’t provide.
