Ditter network ~ every 292 kHz 1019 kHz to 6 MHz
« on: August 21, 2022, 0948 UTC »
0935 UTC. Sunday Aug 21  dits about 0.2 seconds apart on these frequencies:  1019, 1311, 1603 kHz, 1895, 2187, 2478, 2769, 3069, 3353, 3644, 3936, 4227, 4519, (4811), 5102, 5394, 5686, (5976), 6368, (6562), (6854)...

These signals are 292 kHz apart. The above frequencies in parentheses are calculated frequencies where the dits should be but were not heard.

1019, 1311, and 1603 are in the AM broadcast band. 4811 kHz had a strong STANAG signal and the other frequencies not heard may be due to propagation.

I have heard two other similar ditters yesterday in the 8000 and 9000 kHz bands but did not think they were related to today's findings. I now believe they are of the same network.

Addendum:  As I look at the 4227 and 4519 kHz signals, I get the impression that every other dit is of a stronger transmitted power, alternating between high power and low power dits. This may be the case on other frequencies as well but it is subtle but most noticeable on the 4 MHz frequencies.
