Try http://www.hamtronics.com and scroll down the menu bar on the left
side to Receiving & Xmtg Converters and then select VHF & UHF Receiving
Converters. These will listen to any mode (AM,FM,SSB,CW,PSK31,etc.)
that your I.F. rig can copy. I've built many Hamtronics kits over the
years and they are simple and tune up with a voltmeter. A frequency
counter might be nice to get the oscillator exactly on frequency, but it
probably isn't absolutely necessary.

RAMSEY and TENTEC might be two sources...

Thanks. Ramsey have 10m and 6m RX kits, but they're FM and
the beacons that I was hoping to hear transmit CW. I have a
TenTec kit, but it's more complex than I had hoped and I'm
told that it will work better on 80m or 40m than 10m, so I
will probably build it for 40m when I eventually pluck up
the courage (and source a nice vernier for the tuning).

Thanks,
