Shortwave Radiogram schedules, Friday-Sunday
With difficult reception this time of year in some parts of the world, this weekend we will transmit a slow, robust mode: Olivia 32-1000 (32 tomes, 1000 Hz wide). The extra "twist" in this exercise is that the Olivia 32-1000 will be centered on an audio frequency of 2000 Hz. You will hear the difference! This shift is audio is not entirely silly: If there is co-channel interference consisting of human voice, music, or even jamming, most of the noise will be in the lower audio reaches. Olivia 32-1000 at 2000 Hz might be able to escape the interference. The audio extends to 2500 Hz above and below the carrier, so make sure your bandwidth is not too tight. If you are listening on WINB, a manual change of mode and audio frequency might be necessary.
A good five-minute video explaining Shortwave Radiogram has been produced by Norm KC9CSC at his Shacking Off YouTube channel. This is in addition to the videos of the entire half hour of last weekend's Shortwave Radiogram (program 172) kindly provided by Scott in Ontario (Saturday 1330 UTC) and Frigid RF in Virginia (Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.
This weekend's show is in MFSK32, Olivia 32-1000 (at 2000 Hz), and MFSK64, with nine MFSK64 images.
Here is the lineup for Shortwave Radiogram, program 173, 8-11 October 2020, in modes as noted:

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. 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 email@example.com , 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!
