@popshopradio.bsky.social I thought 7730 kHz was free from WRMI's audio processing but it's not.

Look at this waveform view from a portion of this week's broadcast. Notice the choppiness in the audio; not continuous sine waves.
I think it's another artifact of their processing.

@swradiogram.bsky.social No images decoded in northern Florida, USA from the overnight broadcast on 5850 kHz.

An early sign of spring here is the blooming of azalea bushes around our house.

Suddenly WRMI 5850 kHz audio decreased significantly at 04:05, returned and again at 04:07 UTC, then entire transmission went silent at 04:11, returning to full-strength in less than minute later. @swradiogram.bsky.social

WRMI's program schedule on 9955 kHz stays loyal to Eastern time. Therefore, today's Shortwave Radiogram on 9955 will be at the same local times in most of North America: 1030 EDT, 0930 CDT, 0830 MDT, 0730 PDT. The UTC time changes: now 1430-1500 UTC.

Oops, I made a collage of images from the 0330z @swradiogram.bsky.social via WINB 9265 and then totally forgot to post it. The signal was quite good, unless it wasn't, then it was bad, lol.

The His & Hers Restaurant pic particularly showed the struggle.
