Last weekend we enjoyed good reception except for the Sunday 2330 UTC broadcast,which was inaudible just about everywhere. I had no reception in Virginia, so I used an SDR in Montana. That signal deteriorated quickly, so I switched to a receiver in Michigan, which also went downhill. Finally, I found a receiver in Ohio that allowed me to complete the half hour.
This weekendâs Shortwave Radiogram will mostly be in MFSK32. There will be one weird twist:One news item will be transmitted in 8PSK-500F, followed by 8PSK-1000F. This experiment is in the category of probably-wonât-work-but-worth-a-try. These 8PSK modes are very fast (1690 and 3386 wpm) and really designed more for VHF/UHF than for HF. But their forward error correction (hence the F) might give them a chance on HF.
The chances for successful decode of the 8PSK modes will be improved by using the pilot tone feature in Fldigi: Configure > Miscellaneous > Misc > Modems > PSK: In the 8 psk box, select Pilot tone.
Unfortunately,the 8PSK-F modes cannot (yet) be decoded by TIVAR or AndFlmsg. If you use these Android apps, you will be left out for only about a minute.
There are slower 8PSK-F modes (125F and 250F) perhaps more suitable for HF, but I have had problems decoding them from recordings. We will try these versions of 8PSK later when any bugs are fixed.
Here is the lineup for ShortwaveRadiogram, program 22,18-19 November 2017, all in MFSK32 except where noted:
