Swedish MSKMinimum-Shift Keying (When Shift/Bd = 0.5. It is impossible to get this ratio to be lower than 0.5, hence it is called the 'Minimum' shift.) transmitters can easily be identified in the waterfall diagram by their fishbone-like modulation pattern. This seems to belong to the idle phases while the pattern seems to become more random while transmitting data.
The data section in the transmission presented here for SHR is quite similar to that of SAS at the same time. Both transmitters appear to be synchronized.
