Shortwave Radiogram, del 30/12/22 al 2/1/23: programa 285

I hope you have been enjoying the holiday season. Best wishes for the new year. Bear with me if I type “2022” a few times when I should type 2023.

And if you were affected by Winter Storm Elliott (where did they get that name?), I hope the recovery is going well.

Last weekend the Sunday 2330 UTC show was missing. Jeff White informed me that WRMI’s 7570 kHz transmitter “blew a 4CX3000 tube when it was turned on just before 2300 [UTC]” The cold weather which reached Florida caused problems at WRMI. Cold weather does not usually hurt tubes, but power fluctuations caused by Florida’s idea of cold weather does cause some tubes to blow.

That 7570 kHz transmission is scheduled to switch to Saturday 2300-2330 UTC this weekend. This will avoid a conflict between Shortwave Radiogram and The Mighty KBC, which moves to Sunday 2200-2400 UTC on 5950 kHz from WRMI, starting January 1.

A video of last weekend’s Shortwave Radiogram (program 284)  is provided by Scott in Ontario (Friday 1300 UTC) – it’s a chance to decode the “Holiday Spectacular” if you missed it. The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

Here is the lineup for Shortwave Radiogram, program 285, 30 December 2022-2 January 2023, in MFSK modes as noted:

“This is a Music Show” Most of the show is a music show, but the host transmits some MFSK-64 text and image near the end of the broadcast.  It’s transmitted on WRMI, Thursdays at 0200-0300 UTC on 5850 kHz (Wednesday evening in the Americas). Also look for a waterfall ID at the beginning of the show.    @ThisIsAMusicSho
