Shortwave Radiogram, 26-28 February 2021

Last weekend’s experiment with Khmer text was usually successful. There were examples in which the MFSK64 English decoded perfectly, but the Khmer followed it showed some errors. This is not too surprising given that printing the Khmer seems a rather complicated process, with the   “carriage” backing up to complete some of the characters.

Here is the Khmer as decoded by Dana in California, 21 February 2021, 0811 UTC, 5850 kHz from WRMI Florida …

“This is a Music Show” Most of the show is a music show, but the host transmits some MFSK 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) and a new time also on WRMI, Wednesdays at 2100-2200 UTC on 7780 kHz (aimed towards Europe) .

New York and Pennsylvania NBEMS nets. Most weekends, as KD9XB, I check in to the New York NBEMS (Narrow Band Emergency Messaging Software) net Saturday at 1300 UTC on 3584 kHz USB, and the Pennsylvania NBEMS net Sunday at 1230 UTC on 3583 kHz USB (with out-of-state check-ins now starting at 1130 UTC). Check-ins are usually in Thor 22, and messages are in MFSK32. Messages generally use the Flmsg add-on to Fldigi. If you are a radio amateur in eastern North America, feel free to check in. Outside the region, use an SDR in the eastern USA to tune in and decode. You do not need Flmsg to check in, and most of the messages can be read without Flmsg. If you can decode the net, send me an email to radiogram@verizon.net , or tweet to @SWRadiogram, and I will let them know you are tuned in. USEast NBEMS Net: Please also note the USEast NBEMS Net, Thursdays 0000 UTC (Wednesdays 7 pm EST) on 3536 kHz USB.                

George in Greece used MultiPSK to decode the 0800-0830 UTC transmission, 7730 kHz from WRMI Florida, received via SDR in Missouri. (Good results, but a sample rate correction is needed. I have not yet attempted such a correction using MultiPSK.) …
