[R-390] MY EXPERIENCES WITH INTERNAL PRODUCT DETECTORS

[joldenburg2 at new.rr.com]

I've pretty happy using the CV-591A converters. They work well and really are not that large, after all the R-390a is not a compact receiver. The choice of manual or crystal sideband slicing is nice and with the BFO off it offers selective sideband AM. Never have been able to find a CV-157, they seem to be as un-obtainium (maybe more so...)as a R-389 <sigh>.

There where some R-390A's converted for Mexico that had built in SSB capability. I don't remember all the details and have only seen one on ebay and another at Dayton long ago.
