![]() wrote in message ups.com... [snip] Many radios would sound much better with some attention to the audio chain. I used to think that a "little" distortion didn't matter. After all the signals get pretty mangled by the ionosphere. And I was wrong. It makes a great difference. I have spent the day listening to HF and going back and forth just to get a feel for it. The Radio Amateur's handbooks have some interesting articles about increasing intelligibility in radio transmissions. The older ones will have articles about AM ham radio transmissions. While I would love to buy a really "good" receiver like the AOR7030+, or one of the better Drakes, or even an NRD, money being rather tight, I am happy to get any improvements I can. Terry You might want to consider a tube radio. A tube radio will get the best performance from a simple diode detector. The diode detector works quite well, except when the voltage across it gets low. As the voltage gets low, the diode's equivalent resistance goes up rapidly. Working the diode at a higher average voltage and into a high impedance load minimize these problems. In general, the consumer SW sets will sound better than the communications/ham receivers.
