the Russian .750Hz offset net

750Hz_RUS

750Hz_RUS_baudot
A quick note about a weird Russian net using .750Hz offsets
Rare traffic modes are CW-FSK & 50Bd/250Hz encrypted Baudot (showing zzzzzzzzzzzzzzzzzzzzz string at the end of crypto data) -see above-

Frequencies logged so far:
22820.75
16263.75
16247.75
15803.75
13672.75
13363.75
12025.75
11074.75
10792.75
10253.75
9304.75
9134.75
9049.75

6854.75
5384.75
4864.75

This net is idling 24/7 on « MARK » tone on many freqs at same time.
The MARK tone is located -125Hz from the zero beat, so freqs = xxxxx.625Hz.
This net has some silent periods from time to time but it can be easily identified because of the specific glitches heard on the tone carrier (as shown on the above screenshot) and with the .625Hz steady tone.

PS: Russian origin has been determined by an unique HFDF (direction finding) check by a German guy.

18650.0 LSB Pactor-III net

This week-end, copied some Pactor-III tfc on 18650.0 LSB (offset +1600Hz) simplex tfc between 2 stations having around 60Hz freq difference (this does not helps man-in-the-middle catches)
Unfortunately, decode was possible just for some words only:

8776.8 USB unid Asian? net

8776.8u_comms
An unid net spotted tonight, fair to good signal for the guy passing the data (call-sign 0JP).
Other players are mostly unreadable at Home.
Accent makes me thinking it comes from Asia (note: Bangkok Meteo on 8743.0 USB was pretty strong).
Station used an odd alphabet, as shown above on my transcription tentative.
