Relative to my 1983 Kenwood R-2000 (http://www.rigpix.com/kenwood/r2000.htm), my K3 sounds awful when listening to any AM broadcast stations. I have the 6KHz and 12KHz filters installed and despite widening the AM IF bandwidth to 10KHz and spending many hours fussing about with the RX EQ, I cannot make the K3 to sound even remotely enjoyable. Quite frankly, this is really annoying me although I am impressed by the K3 thanks Elecraft.
I've ordered an Icom SP20 in the hope this will help but while waiting for it to arrive I did some research and stumbled on this archived thread - http://www.mail-archive.com/elecraft@mailman.qth.net/msg52230.html, which suggests the K3's DSP attenuates the IF passband below 250Hz and the frequency range of the IF passband will be widened in a firmware upgrade. So I have the following questions - Why have the low frequencies been attenuated? Is 250Hz the -6dB or -3dB point? Will the passband be widened in an upgrade? I do admit though that the K3's SSB audio is FAR superior to that of the R2000 (but it does have a VFO resolution of only 100Hz). The K3's SSB audio does sound great.
