Before MLB.com came up with their odd method of streaming HD (really very good), I would listen to WCBS am out of New York for the nightYankees games. What actually worked the best, even though I had the 6 kHz filter, was 1.8 kHz filter SSB reception with the shift adjusted for best clarity, and u

Dave, you've gotten a lot of good inputs that likely addresses the problem you noticed. There is a couple of other sources of irritating distortion on the "short waves" where skip reception is common when you are listening to a full double-sideband full-carrier A.M signal that are caused by propag

This limitation of audio bandwidth of AM signals to 1.35 kHz is only true when the AM carrier is centered in the roofing filter passband. As Don says, AM is a double sideband signal, but you only need to receive one sideband to hear all the audio. You can use the big knob on the K3 to tune slightly

I have the 13Khz filter fitted in my K3 which may be a better option than the 6Khz. The am audio is quite superb. Phil, ZL1PB. Sent from my iPad __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http:

Dave, AM is a double sideband signal, so the audio you receive will be only about half that of your filter setting. The 2.7 kHz roofing filter is limiting the demodulated audio to about half the width of that filter - 1.35 kHz - so you will not hear any high audio frequencies no matter how w

Dave, The fidelity will improve significantly with the wider filter. Regarding the distortion, try backing off on the RF Gain control a bit and see if that helps. It does here. You might also find that there is less distortion with Synchronous AM detection engaged. 73, Dale WA8SRA On 12/30/

I just received and assembled my K3 about a week or so ago, I only have the 2.7Khz. filter that was shipped with the kit. I love the operation on SSB and digital modes BUT, when listening to the DX60 AM net the audio is quite distorted. I started out with the filter set to NORMAL and then made i
