Thanks to everyone who reported on last week’s test of gaps and no gaps before the image headers. No prominent pattern emerged during my first look at the results, but I need to do a more systematic analysis.
My usual routine is disrupted this week, so I don’t have time to insert experiments this weekend. We will revert to the traditional method of gaps before the image headers

“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. thisisamusicshow@gmail.com www.twitter.com/ThisIsAMusicSho/ ; @ThisIsAMusicSho https://thisisamusicshow.com
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 1200 UTC on 3584 kHz USB, and the Pennsylvania NBEMS net Sunday at 1130 UTC on 3583 kHz USB. 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, Wednesdays 2300 UTC (7 pm EDT) on 3536 kHz USB.
