Yeah, that 75M AM window from 3875kHz - 3885kHz kind of sucks, since you have those dudes on LSB 3878kHz and slop over from 3892kHz. Yeah, you can narrow your bandwidth, but then that takes out the whole reason that we want AM, fidelity. 14.286MHz AM is a wash, due to SSB, but Timtron's suggestion of 14.320MHz - 14.350MHz AM was way better for 20M. At least it was for me. Most of the time on 40M 7290kHz and 7295kHz is SSB free, but that just two FREQ's. Then, you still have international broadcasters jamming that up. On 80M, 3733kHz seemed fairly open to the AM group down there, but isn't that open to Advance and Extra Classes? What sucks even more is that in another month thunderstorms will clog things up with crashes down there. Yeah, in May Sporadic "E" will open up 10M AM on 29.000000MHz and 50.400MHz on 6M, but that leaves a dry spell called Spring time. I'm not hearing much AM anymore on 1885kHz 160M. What's up with that? Just a noisy winter? Looks like we've got to fight for AM. Huh.... Well, if we can ever find pockets of 2M AM, then we could take advantage of Tropo. I've got a decent rig for that band and mode, but nobody here wants to do that locally. Hell, I can't even get them to do 50.400MHz and 29.0000Mhz AM here. The big buzz where I am is C4FM Fusion DV. That's nice, and I'm glad to have an HT that now does that, but AM? No interest here. Kind of the same deal here with 222MHz. I seem to be the only one that wants to keep that band alive. Oh yeah... Here's another AM'ers site,
