Shortwave Radiogram, for the next two weekends

Shortwave Radiogram

Shortwave Radiogram

Hello friends,

This email will provide information on the broadcasts for the next two weekends (47 and 48)

 

A special broadcast of Program 48 will be a demonstration of Shortwave Radiogram for the meeting of the National Association of Shortwave Broadcasters (NASB), this year hosted by SonSet Solutions in Elkhart, Indiana.

Reception of Shortwave Radiogram will be on a SonSet radio, an inexpensive receiver designed for use in developing countries. Using an antenna on the roof of the steel warehouse building, replete with electronic equipment in operation, the signal will somehow be fed to the SonSet radio, and the modes will be decoded from what is received. What could possibly go wrong?

If for some reason an adequate signal does not reach the SonSet radio, Plan B will be to use audio on an mp3 recorded from program 47, using an SDR somewhere. For this reason, programs 47 and 48 have similar formats, but the content is different.

Both shows will include slow modes, suitable for poor reception, such as on low-cost radios inside a steel building. And there will be some text in non-Latin alphabets.

For logistics reasons, the first transmission of program 48 will be moved up to 0800 UTC on 14 May. To compensate for program 47 being bumped from the 0800 slot, program 47 will be broadcast at 0800 on 21 May. See this schedule chart …

Last weekend’s Shortwave Radiogram, program 46, experienced ups and downs of propagation. The Friday 2030-2100 UTC transmission continues to be difficult to hear most places in the world, and even most places in the USA.

The Throb2 “surprise mode” saw errors in many places where the MFSK modes had no trouble. It’s a reminder of why we don’t use Throb more often, although ThrobX might be worth a try in a future broadcast.

You can see results from program 46 at https://twitter.com/swradiogram . Roger’s analysis of last weekend’s Shortwave Radiogram, as well as IBC and KBC, is available here.
