After several days of browsing through European based remote SDR receivers, I've noticed heavy use of the 11 meter band for paging activities (among other digital modes).  All have been using POCSAG.  The UK frequencies are often quite active, as is 27.300 MHz (although I can't figure out where this one comes from).  The 27.600 MHz one is based somewhere in Northern Europe and is extremely strong, often pushing past S9+30db signal strength.  The 26.950 MHz pager appears to be operating out of The Netherlands and transmits an idle signal even when no data packets or pages are being sent.  26.835 MHz appears to be used by both UK-based pagers and on-site (possibly hospitals) paging systems in Russia.  26.945 MHz is heavily used in Russia, often with several signals on 26.945 MHz FM at once.
 

[Original post in italics]

Pagers seem to cluster around certain frequencies, namely the 26.2 MHz to 26.5 MHz region, the 26.6-27 MHz region, the "in-band" pagers), and then those operating on the "high channels" (above 27.4 MHz or so).  The 26.6-27 MHz area seems to be the most active, although the UK hospital pagers on 26MHz are often incredibly loud during band openings and can be heard all over Europe.

The Europeans seem to be a lot more fond of both the FM voice mode and using 11 meters for digital modes and local paging. 

I have added frequencies in use outside Europe, but since most of my monitoring is either done locally (in the USA) or via remote receivers (remote SDRs, usually from the KiwiSDR list, etc) - any and all contributions to the list are welcome.  The list will be updated as often as possible.  Europe has the band 26.225 MHz to 26.935 MHz "harmonized" for "EU-wide" paging operations.  Of course, this clashes with or overlaps with several CB allocations, including the 26.565-27.405 MHz band used in Germany, Hungary and the Czech Republic and the 26.5-28 MHz band used in Russia.  On-site paging using the 26 MHz and 27 MHz bands appears to be very popular in both Western Europe and Eastern Europe in addition to Russia, the CIS and the former USSR.

Please note the following:

The 6 "standard" remote control, RC or R/C frequencies are often used for telemetry purposes.  They are often identified by color-coding (especially for R/C purposes).  These channels are 35 kHz from the original band edges of 26.96 MHz to 27.23 MHz and spaced 50 kHz apart.  In the USA, 4 watts carrier is allowed on the 5 original "auxiliary" frequencies and 25 watts carrier is allowed on 27.255 MHz (which is shared with CB channel 23 and therefore usually only used for higher-power applications).  27.255 was added as an RC channel in 1977 when the CB band was expanded from 23 to 40 channels.  These frequencies are used worldwide and often have voice communications heard on them during band openings.

26.995 MHz - Channel 1 Brown Channel or CB 3A
27.045 MHz - Channel 2 Red Channel or CB 7A
27.095 MHz - Channel 3 Orange Channel or CB 11A
27.145 MHz - Channel 4 Yellow Channel or CB 15A - seems to be the most common for wireless keyboards etc.
27.195 MHz - Channel 5 Green Channel or CB 19A
27.255 MHz - Channel 6 Blue Channel or CB 23

The UK R/C frequencies also use a color-coding system, with more of their frequencies shared with CB channels.  Original UK specifications called for 20 kHz wide data, newer specs call for 10 kHz narrowband.  27.255 MHz was the original RC frequency for the UK, with "side" frequencies 25 kHz above and below (27.230 MHz and 27.280 MHz).

26.975 MHz - Black Channel
26.995 MHz - Brown Channel
27.025 MHz - Brown-Red
27.045 MHz - Red
27.075 MHz - Red-Orange
27.095 MHz - Orange
27.125 MHz - Orange-Yellow
27.145 MHz - Yellow
27.175 MHz - Yellow-Green
27.195 MHz - Green
27.225 MHz - Green-Blue
27.245 MHz - Blue (UK spec)
27.255 MHz - Blue (US spec and de facto worldwide spec)
27.275 MHz - White or Purple

New Zealand R/C frequencies are even more varied, with heavy use of the 29 MHz band (see also: Australia).  In New Zealand, AM mode is the only mode allowed in the 26 MHz and 27 MHz bands.  AM and FM are allowed on 29 MHz for RC purposes:

26.975 MHz - Channel 197
26.995 MHz - Channel 199
27.020 MHz - Channel 102
27.045 MHz - Channel 104
27.070 MHz - Channel 107
27.095 MHz - Channel 109
27.120 MHz - Channel 112
27.145 MHz - Channel 114
27.170 MHz - Channel 117
27.195 MHz - Channel 119
27.220 MHz - Channel 122
27.245 MHz - Channel 124
27.280 MHz - Channel 128

     I still remember when Radio shack sold the CB digital pager in the 1980's that was in between CB channel FREQ's. (What freebanders called the "A" channels.) The offices at college (Back in 1987.), had me help extend the range of their system, so I used their filing cabinet as a GND Plane. Worked pretty good. I'm guessing that disappeared with the introduction of cell phones.
From DC to light, I take a huge spectrum bite!

Re: European Paging Pager Frequencies 11 meters
« Reply #2 on: June 12, 2017, 2000 UTC »
The RadioShack pagers operated on 27255 kHz / 27.255 MHz (CB channel 23).  While FCC rules permit up to 4 watts on the "A" channels but up to 25 watts (carrier power) on channel 23.  The RadioShack paging transmitters did 6-7 watts carrier power IIRC, which, with a ground plane antenna, I imagine produced some impressive coverage.

I have personally monitored (and recorded) POCSAG traffic on 27255 during band openings.  I know this frequency is used for point-to-point data links in specialized "niche" systems like lightning detector systems today.  The fact that pager traffic has been heard recently on 27.255 MHz channel 23 indicates that at least some of the RS paging transmitter systems are still in operation.

I was just at Shopper's Drug Mart here in Ontario. They give you a pager that vibrates when your prescription is ready and you can do the rest of your shopping. Looking at the backside in the fine print it operates on 26.995 Mhz, channels 3A to some.

Since the pager you're talking about has to work throughout the store, I imagine its associated transmitter operating on 26.995 MHz is not transmitting ISM power levels, but CB power levels (4 watts carrier or so).  Even with an inefficient back-of-set type of antenna, 4 watts on 26.995 would be very effective and covering an entire store with small receivers equipped with even lower efficiency antennas.  Nice find, dave524.  I've seen lots of restaurant pagers operating in the UHF band (usually 467.750 MHz) but its awesome to hear that there are systems operating on 26 MHz and 27 MHz as well.  I personally think that with the right antenna system and the fact that 26/27 MHz paging systems provide higher (possible) power levels...you could get a lot more range out of 27MHz over UHF.

I have a feeling Canadian regulations regarding paging on the 11 meter band are similar to US regulations.  US rules allow for up to 4 watts carrier power on the five exclusive "R/C" frequencies:

26995 kHz - 26.995 MHz - RC channel 1 or Brown also known as channel 3A - CB channel 3 +10 kHz
27045 kHz - 27.045 MHz - RC channel 2 or Red also known as channel 7A - CB channel 7 + 10 kHz
27095 kHz - 27.095 MHz - RC channel 3 or Orange also known as channel 11A - CB channel 11 + 10 kHz
27145 kHz - 27.145 MHz - RC channel 4 or Yellow also known as channel 15A - CB channel 15 + 10 kHz
27195 kHz - 27.195 MHz - RC channel 5 or Green also known as channel 19A - CB channel 19 + 10 kHz


As mentioned before, 27255 kHz - 27.255 MHz is also listed as part of this service, but has a higher maximum power level of 25 watts carrier power and is shared with CB channel 23.  27.225 MHz is often referred to as RC channel 6 or Blue.  Due to the potential for interference on 27.255 MHz, it seems like most of the systems like what dave524 is referring to seem to stick on the data only frequencies where voice communications are not allowed.
