21:00 UTC It was a while, but this evening telemetry was load and clear in JO21ho. The last periode there was a lot of other for me unknown modulation transmitted by this Satellite.
RS30 US 168 IBS 8 USUN 0 ISUN 0 ITXA 0 ITXB 0 TTXA 65 TTXB 66 TNAP 80 TAB 66 MSEP 2 MCON 53 SMA 87 SMB 4 MRXA 2 MRXB 2
RS30 US 167 IBS 9 USUN 130 ISUN 243 ITXA 0 ITXB 0 TTXA 65 TTXB 66 TNAP 80 TAB 66 MSEP 2 MCON 53 SMA 91 SMB 4 MRXA 2
MRXA 2 was the last CW, after that the other unknown modulation started again. It sounds like SSTV but is isn’t.
This is data transmission with a system called DOKA.

Mike,
I can’t find any information regarding decoding DOKA-B.
Do you have any idea why this isn’t available?
