Hi Andy, well it looks like all of Jim's circuit would work at 137 except
the input phase splitter, and it needs a bit more gain.

Firstly, Jim, can you send me a copy of your vectorscope circuit please -
it
may be a case of "Coals to Newcastle" but I'm intrigued ! Now, how about
the next version, a direct conversion receiver generating quadrature
signals
at 137kHz then having masses of low frequency gain before the X/Y plot ?
