Check most evenings on 75M from 3875kHz - 3885kHz for nightly AM'ers. Also, early afternoons, before 3PM EST, for AM'ers on 40M 7290kHz. There are some big-gun AM'ers on 160M as well, like around1890kHz. Now, if these warm weather thunderstorms can just keep their distance, and not trash the lower HF bands at night, there's lots of AM to be had. BTW, with some Winter Sporadic "E" leftover, you may hear 10M AM on 29.000MHz - 29.200MHz. There's some folks doing 20M AM. The AM Rally lists 14.286MHz, but I was hearing more AM up in 14.330MHz daytime. So, there could be a lot of AM to be had. And, before 2M FM and SSB, there was 2M AM. That is very sporadic upon whom does that around this country anymore, but in FL, where you are, Tropo propagation could bring you 2M AM DX stations. And yes, 6M 50.400MHz. I use to join in those 6M AM round table Saturday night winter evenings back in the mid-90's. Some of those hill toppers were over 70 miles away! Hey... Ya never know...
