R-390A with CV-591A/URR
Here we have a R-390A, teamed up with a CV-591A SSB converter.
The R-390A bears a AMELCO tag, order number 35064-PC-62. As visible,
it is complete with those nasty radio-active meters removed from
so many R-390's, apparently because military personnel were ingesting
them. Bad chow I guess.
The CV-591 is fun. It delivers "punchy" audio, and even tries to
select the correct sideband on its own. LO frequency injection
to the product detector can be selected from two xyals, or from a
VFO. Of the 3 CV-591's here at KA4RSZ, all seem to have different
xyals. Wonder why....
