At Cryptomuseum we are analysing the Rohde&Scharz GA082 Telex Analyzer. It is not a demodulator, but an FSK analyser to analyse received FSK signal from (radio) demodulator. It had lots of secret modes, of some we already have published here:
https://www.cryptomuseum.com/telex/rs/ga082/
The picture is from the cartridges we found recently: Secret modes that can be FSK analysed by the GA082.
We found out that the Transtel printer has a variant to enable to print Cyrillic. This is -if we are correct- the Transtel AH.11.H type printer. This one could be connected directy to the GA082 to print out messages.
As of today we are able to receive Russian marine info's. But we cannot show cyrillic because we don't know how the printer translate the serial HEX info to Cyrillic characters. We hope that someone here has more info about this.
To have a glimpse of how the printer looks:
