I blew off C2C AM and woke-up listening to the AM'ers on 3885kHz. Anyway, I heard them talk about an AM Marathon for New Year's Eve and New Year's Day. Then, the annual AM Heavy Metal Rally, for the weekend of 1/4 - 1/5/2025. (Called that since the idea is to use older tube Amateur and military gear, but anyone can get-in on this.) Where to monitor, and, or, talk?
160M - Centered around 1885kHz.
75M - From 3873 - 3885kHz. However, there is AM activity down near 3700kHz, in the Extra Portion of the band.
40M - From 7285 - 7295kHz. (Albeit, later in the day SW Broadcasters still crash this on 40M.)
20M - Call FREQ has been 14.286kHz. However, due to lots of SSB'er there, Timtron, WA1HLR suggested using from 14.320 - 14.345MHz. (I tend to agree with that practice.)
17M - Upper portion of that WARC band.
15M - Suggested 21.420 - 21.445MHz.
12M - Upper portion of that WARC band.
10M - Centered around 29.0000MHz (Calling FREQ.), with activity about every 10kHz up.
6M - Centered around 50.400MHz (Calling FREQ.), with activity about every 10kHz up.
2M - This has been considered a 'Local Option' upon where to operate. However, a suggested Calling FREQ could be 144.300MHz.
222MHz, 902MHz, 1.2Ghz, and up? Well, you could always experiment with AM where the band calls for 'Mixed Modes'.
Regardless, the idea is to have fun on AM. Hear you on? Hope so. OH yeah!!! The AM Rally starts on February 1st, 2025.
