Hi Bernie, I have gone back and forth on the receive audio question with my rigs. I have never had a PC controlled receiver, but I have a Kenwood TS870 which is a 24 bit dsp firmware receiver. I have the 1000MP Mk V also and I agree that the stock audio is not very good. I widened the stock 6 KHz passband AM IF and tapped the AM detector and brought that signal out to an external tube push pull amp and speaker. Those two things made a vast difference on AM and it sounds like a tube boat anchor rx now. Next I get the 75A3 and fire it up and I'm not very thrilled with the audio quality. At this point the audio I get from the stock TS870 with a 14 KHz passband is almost as good as the modified Yaesu. 75A3 is worst of the three. But I tap the detector on the A3 and with a 10 KHz AM passband, put its audio out to another p.p. vintage AF amp and set of speakers. Now I prefer it over the TS870 and it is at least as good or better than the tapped and modified Yaesu. I have never had a SX28 or any of the "audio" ba receivers (many of which seem to be general coverage) but I have concluded that most ham receivers need some help of one sort or another as they were not intended for great audio but rather for chasing dx.
