In the last 2 or 3 days, a POCSAG on 26.900MHz has been strong in Italy.

Yessir, 26900 kHz 26.9 MHz paging system is powerful.  I'm not 100% sure where it is located, but it seems to have several different transmitters operating on that specific 26.900 MHz frequency, as when the band is open there's often various signal strength signals coming in. 

Do you often hear the POCSAG paging systems on 29.800 MHz and 29.900 MHz?

Last summer I received similar RTTY signals around 29800, I thought they were radio fishing buoys, I should have some videos on YouTube
