Shortwave radiogram schedules, Saturday-Sunday


Hello friends

This weekend we will finally transmit a photo of a cicada. The present brood of the 17-year cicadas, and their wonderful sound, won't be around much longer. And I probably won't be around for their next appearance, so I am enjoying the critters as much as I can.

Speaking of things that are going away, this weekend will be the last transmission of Shortwave Radiogram on WRMI's 9955 kHz, Saturday 0000-0030 UTC (Friday evening in the Americas). WRMI has a new show for that slot. The 9955 kHz frequency was great while it lasted, reaching from South America (its nominal target) to upper Alberta, and sometimes Europe.

A video of last weekend's Shortwave Radiogram (program 205) is provided by Scott in Ontario (Friday 1300 UTC). The audio archive is maintained by Mark in the UK. The analysis is prepared by Roger in Germany.

Here is the lineup for Shortwave Radiogram, program 206, 27-30 May 2021, in MFSK modes as noted (with ten MFSK64 images):
 1:41  MFSK32: Program preview
 2:44  Eclipse festival seeks hams and SWLs
 5:04  MFSK64: Gardeners battle invasive goutweed*
11:29  This week's images*
28:34  MFSK32: Closing announcements

“This is a Music Show” Most of the show is a music show, but the host transmits some MFSK-64 text and images 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.

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, 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.
Thanks for your reception reports!
