I wish I could report I made two hundred 40M contacts on the MHST including DX to Western Samoa, but alas that is not the case. The issue is the transmitted signal and not receive.

While I can abate the spurs and image signals using the QUISK tool, one additional frequency is getting transmitted. It is stronger than the operating frequency, of the opposite sideband and is not touched by the QUISK controls. I can even see it on the Half Moon Bay SDR site which is 300 miles from here.

Thus, the transmitter remains a problem for me. I need to do a bit of research and see if any other homebrewers have seen this effect.

Them that know can make it go.
