My DSB RX for 10m FT8 is complete and working.
I had a few problems getting the crystal pulled down enough, but a small inductor in series with the crystal did the trick. I shall tell you how I netted the crystal in another post.
So far, ES2AJ (1716km) has been spotted using just the indoor loop at -12dB S/N, which is strong. This means the "big rig" does not have to be tied up when monitoring 10m FT8.
In the end I started with my WISPY RX which I found. The sharp eyed may notice an unused oscillator buffer which can be removed from the board. A simple PCB could be made if this was ever a club project.
All being well, I shall publish the circuit over the weekend.
