I have 2 TMC (Technical Material Corp) "strip" receivers for sale. See spec
sheet at:
http://www.geocities.com/vintagetmc/str5-1.html

Please note that clicking on "next" at bottom of the page brings up 2nd page.

Modules contain crystal overs and demodulators, and are in 5-10 Mhz range. No
power cords or manuals. Interesting cold war stuff, as "war time" modules with
demodulators were kept in sealed containers for secrecy reasons.
Both for $300 Will not sell individually. Shipping extra.
