Shortwave Radiogram

Hello friends,
Most of Europe shifts to summer time on Sunday. The transmission schedule for Shortwave Radiogram remains at the same UTC times, so the broadcast will be one hour later by local time for most listeners in Europe.

I am not aware of any frequency changes. However, The Mighty KBC transmission to North America Sunday 0000-0200 UTC (Saturday 8-10 pm EDT) will be on new 5960 kHz starting this weekend. The usual minute of MFSK32 will be at about 0130 UTC. IBC will also have some schedule changes (see below).

Last weekend’s experiment transmitting MFSK32 text and an image simultaneously went very well. So well, in fact, we will try it again this weekend. This time, I will not reduce the amplitude as much as last week. This might improve the text decode if you are receiving a poor signal. I hope it does not break a transmitter.

The picture and link at the top of this email illustrate the concept of concurrent text and image transmission. A very useful news consumption app, for PCs or for mobile devices, could be MFSK-only, simultaneously decoding text and images, showing one left and the other right, or one top and the other bottom. The app could be used on shortwave or any other radio band.

Also this weekend, we will transmit one news item in MFSK64. This is a faster mode (240 wpm) than our usual MFSK32. The MFSK64 image should exhibit higher resolution.  Both the MFSK64 text and image might be subject to errors if the signal is less than good. If you are unable to decode the text, the original RFA story is here.

Here is the lineup for Shortwave Radiogram, program 40, 24-25 March 2018, all in MFSK32 except where noted:

1:35  Program preview
