Hello friends,
I have produced this week's program (387) using the latest alpha version of Fldigi: 4.2.06.20. According to our expert Tobias in Germany, this version "added short signal ramps to MFSK (and other) modes ... which ... should help initial MFSk synchronization after any signal gaps etc. I hope this will also improve the reliability to receive complete image headers, and thus the respective images."
Let's see if this improves (or impairs) the performance of RSID mode changes and image headers. You can continue to use your present version of Fldigi. The modifications in 4.2.06.20 (that I am using) affect only the encoding.
This reminder that the swradiogram.bsky.social account is now active. This is where I repost listeners' results. And the @SWRadiogram X (Twitter) account is also active, for the time being. I think you can read the bsky even if you don't have a Bluesky account. Let me know if you can't.
A video of last week's Shortwave Radiogram (program 386) is provided by Scott in Ontario (Wednesday 1330 UTC). The audio archive is maintained by Mark in the UK. Analysis is provided by Roger in Germany.
