![]() "COLIN LAMB" wrote in message m... Hello Richard: I think the Cardwell company was owned by another company, which was owned by the Cardwell family. At some point, during the demise of Hammarlund, that company purchased the Hammarlund assets. The specified audio output of the Cardwell receivers is high enough that it was probably push-pull. So, if you ever find one, the audio will probably be good. I just had a thought about searching for this elusive receiver. Check the various manual sources. If there were a few radios made, there must have been a manual floating around. Fun to see one. 73, Colin K7FM I think so too. I'm not quite sure what happened to either Hammarlund or Cardwell. There is some Hammarlund history on the web. At the time the Cardwell RX went on the market a number of receivers had relatively high quality push-pull output stages. The Hammarlund Super-Pro for one and a couple of National receivers, I think the SX-28 and SX-32 had push-pull amps. I can testify as the owner of a BC-779 that the low distortion helps even with CW since distortion magnifies noise. Those having receivers with an external connection to the detector may get surprize if this is connected to a high quality audio system. Most of these connections have DC on them so a series capacitor and a resistor are necessary. An SP-600, for instance, will let you hear all the clipping from the processing on AM broadcast stations. There WAS, dear children, high-quality AM in the dear, dead, long ago before being the loudest kid on the block became the objective.
