Put this in front of the receiver and it'll work to DC.

I think that would be an easy receive converter for someone to build. That way a guy could use his HF rig's DSP filtering.

Hi Joe,

from what I can find in the web it tunes down to (only) 15kHz.
That's probably because  below 15kHz synthesizer sideband noise would
be an issue.
My Sony CRF-1 tunes down to zero Hertz but you can
hear the increasing synth. noise below 15kHz .
But it's still possible to receive the three alphas at ca.12kHz and ca.15kHz.
Maybe when using the broadest filter with 8kHz you can get usable reception
at 8,97kHz.
For a first try I would look for the alphas at ~12kHz.
OTOH, >15kHz you can expect an excellent performance with this rx.
