The band conditions are (rapidly) changing at this UK based SDR receiver.  Numerous Russian and from points in Eastern Europe signals were/are coming through, including the 26.945 MHz and 26.960 MHz data links and pagers and all the taxi cabs.  The 27.330 MHz FM CB simplex repeater is still coming in nicely, but now an UNID language repeater or cross-band link (or gateway?) is blasting through on 27.355 MHz FM (CB radio channel 35 FM). 

The paging system - pager on 27.505 MHz is also back.  I believe this is coming out of Spain.  The center frequency seems to be offset for some of the transmissions, 27.5035 MHz up to 27.5075 MHz so +/- 2.5 kHz or so. 

Bandwidth is a solid 10-12 kHz.  Sounds kind of like POCSAG, but kind of not.  Could be CCIR or another type of specialized paging protocol. 

There are various different types of signals on this frequency, I want to say 27.500 MHz to 27.510 MHz or so would be the band.  Duration is anywhere from 1.5 seconds to 6-7 seconds.  Just data, no voice.  It does not appear to be related to the 27.885 MHz 27885 kHz paging system, but might be related to the one on 27.845 MHz 27845 kHz.

This was (and is) being received by the G8JNJ SDR receiver located in the South West UK.  Wessex SDR receiver.
