M95 has a voice sister station, called V26. It also has a digital sister station that has no specific ENIGMA ID but uses the Chinese 4+4 digital modem.
These stations will run back to back, so you might hear the digital modem, and then a few minutes after that ends you might hear M95, and then a few minutes after that ends you might hear V26.
I do not know if they always do so, but I have seen the same data sent by each, first on the 4+4, then on M95, then on V26.
These stations are typically on three frequencies at one time. 4283 // 7553 // 9153 (or 8073) might be used as a set, and another might be 4243 // 7345 // 9054. Sometimes M95 is on frequency, sometimes it is shifted 1 kHz up or down as if in either USB or LSB modes. Typically the voice and digital signals are in USB. However the station does make relatively frequent mistakes in modes, for example I have seen the three frequency set each using a different mode, so that at one time LSB, USB, and AM was in use, each on a different one of the three freqs.
