Hello friends,
Last week's experiment with the Fldigi alpha version 3.2.06.20 seemed to improve performance with image triggers and modes changes by way of RSIDs. This is because of the increased lag time as each MFSK transmission starts and stops. We need more data before making any conclusions.
I am using 3.2.06.20 again with this week's show. Production was frustrating because the center audio frequency kept veering off of 1500 Hz. The AFC was probably the culprit, but in this version it is permanently on -- unless I am unaware of a setting that allows the AFC to be toggled. There is also a "Disable freq change" button in the RSID menu that I will try next week.
The labyrinth of Fldigi settings is good exercise for an old brain, I suppose.
A video of last week's Shortwave Radiogram (program 387) 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.
