26.695 MHz is a well-known UK paging frequency - technically an offset from the 26.700 MHz European standardized paging frequency.

Depending on where you look, 26.2 MHz to 26.965 MHz is a standardized paging band, other sources say 26.235 MHz to 26.935 MHz and still others say 26.500 MHz to 26.960 MHz...

26.795 MHz also had what sounded like POCSAG on it.  26.695 was certainly POCSAG (and was pretty strong). 

The wider-than-normal 10 kHz wide FSK signal actually might have been 2-carrier MFSK, as the carriers were closer to 26995 and 27005, mark or space moved them up or down roughly 1.5 kHz or 2 kHz, but the whole signal was 10 kHz or 12 kHz wide...compared to the usual 6-8 kHz wide data signals heard on the 25-28 MHz band.

The dits on 27.120 MHz could have been a legit ISM signal or some sort of non-communications signal.  Or, it could be some sort of beacon.  27125 had voice activity on it that would, at times, drown out the 27120 signal.

In regards to the 27.120 MHz signal, there is this:
