[R-390] MF/LF Reception

[Don Reaves]

Good reminder, Bob, to repurpose unused and inexpensive test equipment.

The HP-3586B Selective Voltmeter is hard to beat, once you learn to live
with no AGC and no front end filtering.  I've purchased them for less than
$100, fully operational.  I use one as a stable frequency source.  Dial up
a frequency on the front panel and that signal is available on the back
panel of the 3586B at a 1 volt PP level.  They do make very sensitive
receivers especially for NDB hunting, and the range is audio up to 32MC.
You usually need at least one of those weird WECO to BNC video style
adaptors to connect an antenna via BNC.
