Looking for a communications receiver?
#27

Some of those old receivers don't seem to have a lot of audio power or they are built for some 500 ohm VC speaker. I've seen a few that were modified by changing/adding a new output trans. Probably not much more audio but you could match it to 8 or even 4 ohms.

Probably wouldn't take much to add a little SS Chinese audio-amp.

My favorite receiver, so far, is a little Unusual. It is a NEMS Clarke 1502A which was a US "telemetry receiver". It will do all of the regular stuff + video. It is really hot, surprisingly so on the FM broadcast band and above.

Put into service in about 1960, it would be fun to know who's space shots were monitored on this receiver. I've been going to write about it for a while - -
