Four good flag images from the 2300z @swradiogram.bsky.social via WRMI 9455. The signal started off really strong but got weaker towards the end, but all the text and images still looked good enough.
From coastal Alabama.
Alt Text has all the flag info that was transmitted in MFSK64.

KBC data from this morning indicate that WRMI applies identical audio processing, including reverb, on both 7780 kHz and 5950 kHz.
The resulting ghost echo, delayed by roughly 20 ms, is clearly audible and makes the signal unsuitable for piggybacking digital data.

Colo(u)rful Canadian flags are on this week's @swradiogram.bsky.social as @popshopradio.bsky.social's Poppie fills in for KAE. Loved the trivia on each province and territory. I think the Inuktitut came through well, too. I had no idea it was a supported language in Windows!

Local reception here in northern Florida, USA was a bust. Signal was audible but not enough SNR for FLdigi to do its magic.
