Hello friends,
I am sending this preview earlier than usual because of appointments later in the week.
This week’s Shortwave Radiogram will include another story about the crisis of US international broadcasting. It’s from Radio Free Asia about the loss of most of its shortwave and medium wave frequencies, and how they are continuing on a much reduced transmission schedule using what money they have on hand. The situation at RFA and the rest of US international broadcasting may have changed by the time the program 397 transmissions have all completed. I post much of this news at kaedotcom.bsky.social .
Some notes about Shortwave Radiogram frequencies: Those of us who were tuned in heard no transmission Friday at 0530-0600 UTC on 7780 kHz from WRMI Florida. I haven’t had a chance yet to ask Jeff White at WRMI what happened. When it is on the air, that transmission is almost always heard in New Zealand, and probably in other parts of the southern Pacific region.Ā
Also, please note that the Saturday 2300-2330 UTC broadcast is on three frequencies from WRMI: 7570, 7780 and 9455 kHz. Of the three, 9455 seems to provide the best reception in most parts of the world. Last week, I had fairly good results using an SDR in Australia.
A video of last week’s Shortwave Radiogram (program 396) is provided by Scott in Ontario (Wednesday 1330 UTC). The audio archive is maintained by Mark in the UK. H0b0_Radio in Washington state offer this IQ recording. Analysis is provided Roger in Germany.
