Later I acquired one of the mid-'50s vintage Heathkit Q-Multipliers and attached it to the receiver. I controlled the regeneration by adjusting the r.f. To increase the selectivity, I first made the IFs regenerative by soldering a little piece of insulated wire to the first IF plate, and moved it near the grid connection. I added a homebrew preselector to it to get adequate gain on 15 meters (band 4 gain was just a little wimpy). ![]() I used it for code practice, and was thus able to get my ham license just a few months later. When I purchased it (at a swap meet for the princely sum of $8.00) it worked fairly well. first non-regenerative and non-consumer shortwave radio. It was my first ham receiver and my first "real", i.e. Thanks.I have owned one of these since 1970. Can you tell me anything else about that model? Is that a reasonable price? Are there any known weaknesses, or problems with restoration? This would be my first serious SW radio. Haven't had a chance to fiddle with it, this is info from seller. It appears to be in respectable original condition with manual. ![]() Quote:Originally posted by Schulz:There is an HC S-20R near me that I may be able to get for $30 to $40.
