Eric van Willegen informs me that there will be a minute of Olivia 64-2000 at +/- 49 minutes into his hours on The Mighty KBC.
A good exercise for weak or otherwise bad signals.
Try, for example, on MW via SDR receivers in the Netherlands and vicinity.

Copied 2 episodes of @swradiogram.bsky.social this weekend: 0330 22 Nov from WINB and my usual 0800 24 Nov from WRNI. Near 100% text decode (100% from WINB, a few hiccups from WRNI) and the expected static bursts likely from using a vertical antenna.

As I mentioned in a prior Radiogram post, my 5-6 MHz is swamped with new RF noise, so this week's @popshopradio.bsky.social was an unlistenable mess. Amazingly, though, the image triggered and most of the playlist decoded… The Olivia was the only part that was error-free, however. From Alabama.

I had no luck with the 1530z @swradiogram.bsky.social on 9955, had preempted 9455 for another recording, and was left with a pretty ratty set of images from the 0800z 5850 broadcast due wideband RF noise centered around 5600 kHz. So, not a great way to end a week's recordings. From Alabama.
