[Discuss-gnuradio] Microwave modules receive converter available

[Marcus Leech]

I have a dual-range 432Mhz to 28Mhz receive converter.  It's dual range, 
covering 432-434 and 435-437Mhz, translating
 down to 28Mhz.  They were popular with UHF EME types to use with 
high-quality HF rigs, but VHF and UHF
 multi-mode rigs have now gotten quite good, so receive converters 
aren't quite so popular as in the 1980s when
 I used this for high-speed packet.

The unit is made by Microwave Modules (are they still in business?), and 
it uses a crystal-controlled LO.  I don't
 know what the conversion-gain is, but perhaps 30-40dB?  [There's about 
7 transistors on the circuit board].  The
 noise figure will, of course, be terrible, so you'd need to put a 
good-quality LNA in front of it for any weak-signal
 work.  It worked two years ago when I tested it.  You'll need to find 
a power connector for it, or re-do
 the power entry.

Anyway, if anyone is interested, let me know.  I can package it up, and 
send it on the slow boat...
