[Milsurplus] URM-32A order no.

[David Edsall]

Hi all,

Some years ago I had a URM-32 frequency meter, with AC power supply.  As I
recall, it was not as well made as either the BC-221 or LM, and only the
lowest frequency range, 125 kc - 2.5 mc, was really stable, and the VHF
range, 65 - 1000 mc, was squirrely and any mechanical shock, however slight,
would set the oscillator warbling.  In short, nice to have if you're a
collector, otherwise look for a good BC-221 or LM.  All I have now is a copy
of the TM, which is TM 11-5120 / TO 33A1-5-65-1.
73,
David, W1TDD
