Swiss Army? 3075.0 LSB

2 operators active in plain voice tfc + Telematik-Set TmS-430 FSK 110Bd/337Hz modem (zero beat) – measured with SA at 220Bd (but here and here)

TmS-430 messages were encrypted as the voice coordination contained some codes to decode the messages, the operator said.
Callsigns: « SIMBA » & « THERMOS »

The PTT release tone, usually heard from the Swiss:

Lorient Ecole (French Navy) RTTY tests

Manual sent Baudot 75/850/i (offset +1400Hz) on 6721.0 USB then 5455.0 USB with plain voice coordination

« le » & « vf » were linked using another radiolink as « Lorient Ecole » operator voice has been heard in vf transmission

The Baudot on 6721.0 USB:
