This is a neat grab. I’m randomly spinning through my FLdigi presets which include all the HF FAX frequencies (i think the weather maps are neat) and hear voice! Turns out they transmit voice weather bulletins on here with a robotalker. I’ve never caught one of these particular broadcasts.
To learn more about the HF radiofax weather transmissions that are usually on this and other frequencies, install a program that will decode it (FLdigi seems to do a good job) and hit up the NWS info page for the schedule and frequencies. I’ll post some more info and some of the map captures soon.
