Shortwave Radiogram, 28-31 May 2020: Olivia modes – slowest, slower, slow

I am not sure if I saw any advantage in last weekend’s Thor22 over our usual MFSK32, and not much over the much faster MFSK64. On my PC, the Thor22 performed poorly via WINB, but well via WRMI. There is something peculiar about WINB’s audio. The RSID’s don’t work (for me, anyway) and now the Thor22 doesn’t, either. But, via …

Shortwave Radiogram, 28 November-1 December 2019

Last weekend’s experiment with Persian text was interesting and mostly successful. You can see a near perfect decode via an SDR in Kuwait (close to Iran) during the Sunday 2330-2400 UTC broadcast, 7780 kHz from WRMI Florida (12000 km). You can see Fldigi prints out the Persian right-to-left text by decoding from the videos and audio listed in the next …

Shortwave Radiogram, 21-24 November 2019: Persian text via shortwave

Thanks to those you who participated in last weekend’s test of the low-but-robust modes Olivia 32-2000 and MFSk16. There were some examples of those two modes providing good decodes when the faster MFSK32 and MFSK64 showed errors. With the internet shutdown in Iran is in the news, this weekend Shortwave Radiogram will transmit an excerpt of Persian text, from a …

Shortwave Radiogram, 14-17 November 2019

For this reason, we will add two slow-but-robust modes — Olivia 32-2000 and MFSK16 — to our usual MFSK32 and MFSK64 for this weekend. Each will begin with the RSID more the mode, so make sure your …

On our WRMI frequencies, Shortwave Radiogram stays at the same UTC times, so most of you will be tuning in those broadcasts one hour earlier by local time. On WINB’s 9265 kHz, Shortwave Radiogram stays with local Eastern Time, so the shows will stay at the same local …

Shortwave Radiogram, 31 October-3 November 2019

I just realized that the first transmission of Shortwave Radiogram, today (Thursday) at 2330-2400 UTC, will compete with Halloween. Be careful out there, especially in eastern North America, where storms are expected. Time changes continue this weekend. Many clocks are turning back one hour — despite what I wrote in last week’s email. The European time change is complete,and the …

Most of Europe moves its clocks forward this Sunday, 27 October. The WRMI transmissions will remain at their present UTC times, so they will be an hour earlier by local time in Europe. WINB usually keeps its analog 9265 kHz program schedule fixed to US Eastern time, which will move back one hour on 3 November. Programming on the WINB …
