Hello friends,
Here in northern Virginia, we have just endured two days of high temperatures below freezing. This is unusual for us, but typical for many of you living farther north. Tomorrow, our typical winter weather, reaching above freezing during the day, returns. And by Sunday, hints of spring.
Producing this week's Shortwave Radiogram has been much easier than last week. I am getting more used to the software that runs under Windows 11. The programs that I use primarily are Fldigi (of course), Audacity, UltraEdit, MS Paint, and Snipping Tool.
I still have to find solutions for a few quirks in Windows 11. Firefox windows and even instances of Fldigi will disappear, not to be found in the Task Bar or anywhere else. I know the Firefox windows are running because if they have audio (eg a KiwiSDR), I can hear it. I can access some of the hidden Firefox pages by using Firefox History. Frequent trips to Task Manager are required to clean up all those hidden but running apps and pages.
And Audacity will claim that there is insufficient memory to paste a small segment of audio. So I have to save the Audacity file to a wav file and build on to that. Sorry to bore you with these details!
Please note that the Saturday 2300-2330 UTC transmission is now (or at least least week was) on three frequencies: 7570, 7780 and 9455 kHz, all from WRMI Florida. The 9455 transmitter seems especially to offer DX opportunities.
A video of last week's Shortwave Radiogram (program 390) is provided by Scott in Ontario (Wednesday 1330 UTC). Mark maintains the audio archive in the UK. @CadiereGerald contributes this IQ audio file of the Friday 0530 UTC show. The analysis is provided by Roger in Germany.
