The next Shortwave Radiogram is 1530-1600 UTC on 9955 kHz from WRMI Florida.

Because of the audio on 9955, you will probably need a manual change from MFSK32 to MFSK64.

Once again a great signal but an unusually high level of noise, this time for the @swradiogram.bsky.social on WRMI 9455 at 2300z.

From coastal Alabama, where temperatures are pushing 80Β°F/27Β°C daily already, which makes snowy scenes seem even more foreign.

Bursts of noise marred an otherwise strong signal for the @swradiogram.bsky.social that aired at 0330 UTC via WINB 9265 tonight.

With no decodable results from the 15700 or 7780 WRMI broadcasts, the next @swradiogram.bsky.social caught here on the AL gulf coast was the 0030z WINB one.

The theme for these four images is "symmetry". The symmetry in the spider web image is from the repeating dots of noise, lol.
