Last weekend’s hidden message in Thor Micro at 70 Hz was mostly successful. This weekend, it was my intention to try Throb 1, another very narrow mode, also at 70 Hz, but I could not get a decode from the recording. It seems that Throb 1 does not like the very low audio frequencies. Our hidden message will be in BPSK63F instead, at a center audio frequency of 70 Hz.
This weekend’s show is in the usual MFSK32 and MFSK64, with nine images. Also the BPSK63F hidden message.
Here is the lineup for Shortwave Radiogram, program 117, 12-15 September 2019, in modes as noted:
1:38 MFSK32: Program previoew (now)
2:46 CPJ’s list of 10 most censored countries*
8:50 MFSK64: Exoplanet in habitable zone has water vapor*
13:34 This week’s images*
26:31 MFSK32: Closing announcements
28:17 BPSK63F: “Hidden message” centered on 70 Hz
* with image(s)
Please send reception reports to email@example.com
The Mighty KBC transmits to North America Sundays at 0000-0200 UTC (Saturday 8-10 pm EDT) on 5960 kHz, via Germany. A minute of MFSK64 is at about 0130 UTC. Reports to Eric: firstname.lastname@example.org . See also http://www.kbcradio.eu/ and https://www.facebook.com/TheMightyKbc/.
“This is a Music Show” is the newest addition to digital modes via analog shortwave. 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, Thursday, 0100-0200 UTC on 5850 kHz, and 0130-0230 UTC on 9395 kHz (Wednesday evening in the Americas). Also look for a waterfall ID at the beginning of the show. email@example.com . www.instagram.com/thisisamusicshow/ www.twitter.com/ThisIsAMusicSho/ or @ThisIsAMusicSho
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 1200 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 (PA NBEMS is experimenting with Thor 50×1 for messages). 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 firstname.lastname@example.org , 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 at 2300 UTC (7 pm EDT) on 3536 kHz USB. I will try to check in to this net more frequently.
Thanks for your reception reports!
