I also like to listen to AM SW. If I am stuck with 3KC BW, I'm not going to be very happy with that. As far as I'm concerned it's a bug in the code. That's what they said the 20KHZ (and 6) filter was for? The other night I was listening to SW on 40 (and around 9.5MHZ), it didn't quite cut it, now I know why... Lee, KC9CDT
