[MRCA] RR radio

[Ray Fantini]

If it is a true rail road radio, from what you describe it sounds
something like the T-34 series it may be almost useless. don't know for
certain about the old tube stuff but many years ago I worked with the
Motrack and Micor RR radios, they were all high split 150 to 175 or 160
to 175 MHZ so they wont receive properly on the ham bands unless you do
changes to the front ends, heliacal resonators in those two radios and
if you solve that problem you still have to deal with the problem of
radios built for use on trains require between 40 to 80 volts DC, don't
know where they got it from maybe the locomotive? but the Micor/ track
radios had a completely different power supply from anything else built.
check and see what DC voltage your radio wants first.
