[Milsurplus] CV-157

[Nick England]

The CV-157 spec says 105 lb  but it seems much heavier. It is a great
ISB converter (simultaneous USB and LSB) which includes a motor drive AFC
for tracking reduced pilot carrier ISB transmissions. It has 44 tubes and
lots of circuits to align. I really enjoyed spending several weeks learning
how it works and getting mine running. Acquisition cost is low because sane
people don't want something that big and heavy. Anywhere from $10-100 is
reasonable. Hard to beat if you want an interesting and challenging
project. I enjoy projects but YMMV.

The TMC CV-591 is much much smaller, lighter, easier to use, and more
expensive.

There aren't any ISB or pilot carrier signals to copy anyways so audio
performance
is about the same for regular SSB voice.

OR just switch your rcvr to CW and MGC, offset the BFO, turn down the RF
gain, and turn up the AF gain and SSB voice sounds just fine.
