Shortwave Radiogram, del 26 de Mayo al 7 de Junio: programa 257

Due to family activities (again), Shortwave Radiogram program 257 will be broadcast 26-31 May 2022 and repeated 2-7 June. Because of the complexity of uploading the programs to WINB and WRMI, the easiest solution in these situations to repeat a show from one week to the next. Even though this is the second repeat broadcast within a few weeks, this probably will not happen often in the future.

Apologies if you were tuned in to the 2330-2400 UTC broadcast, 22 May, on 7730 kHz from WRMI. The transmitter abruptly went of the air about 2/3 through the transmission. I haven’t found out what happened, but WRMI’s transmitters, antennas, feedlines, etc, are rather old, so these disruptions are not unusual. Your patience is appreciated.

A video of last weekend’s Shortwave Radiogram (program 256) is provided Scott in Ontario (Friday 1300 UTC). 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 257, 26 May-June 7 2022, in MFSK modes as noted:

  1:36  MFSK32: Program preview
  2:54  MFSK32: Why pipe organs sound lower than expected* **

“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
