I'm looking for additional outboard SSB product detector units for my
SP-600's. I'm using HC-10's with my R-390A's but would like to find
something a bit more reasonably priced for the SP-600's. What might
work OK would be a Central Electronics "Slicer". Also, there was a
Canadian fellow advertising a kit, but I don't have his info. Any leads
or offers of gear would be appreciated.
