Last weekendâs experiment with the very fast 8PSK-500F and -1000F modes was interesting and fun. There were not many 100% decodes, but they did include listeners in Belgium, France, and Germany tuned to the transmitter in Bulgaria,as well aslisteners in Texas and Oregon tuned to WRMI Florida. Several listeners did successfully receive entire paragraphs, but the decode turned to gibberish during fades (which are not uncommon on shortwave!). We will try more experiment with the 8PSK modes on future shows.
Special all-Olivia-64-2000 broadcastthis weekend
This weekend, we will shift from the very fast to the very slow. In the past few weeks, the Shortwave Radiogram transmission Sundays at 2330-2400 UTC on 11580 kHz from Florida has experienced poor reception in most parts of the world.To improve the chances of a successful decode, this broadcast only (number23S)will be in the Olivia 64-2000 mode. It will consist of one Voice of America news story. The broadcast will begin with a brief voice intro, then theRSID for
Olivia 64-2000. If the RSID does not work, you might have to fine-tune the audio frequency for a correct decode.
Olivia 64-2000 is very slow, about 28 words per minute, but robust in difficult conditions. Please note that the text will not print out until a few seconds after you hear the tones (if you hear them). Please record yourreception if possible. We may be stretching shortwave to its limit.
The other three broadcasts thisweekend will be in the usual MFSK32, with four images.
