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

10/11 meters / Re: ROS data mode Digital net on 27635 kHz

« on: June 04, 2017, 1923 UTC »

Interesting post, I've noticed digital nets on 27500 kHz USB / 27.500 MHz USB as well as what seems to be the most common European CB band ROS frequencies, 27235 kHz USB and 27245 kHz USB / 27.235 MHz USB and 27.245 MHz USB mode.

I've monitored PSK31 on 27500 kHz in the past, and have come across digital modes (nearly always ROS digital mode) on 27235 and 27245 while browsing through UK and mainland Europe based remote SDR receivers. 

Always glad to know there's digital activity on 11 meters, in the form of PSK31, ROS, or even digital SSTV.

Much stronger signals than traffic heard 5 kHz down on 6900 kHz LSB.  Mention of California and Virginia.  Two OMs talking.  SIO 333 signals, with some minor fading but considerable storm static QRN.  Casual ham radio operator-like conversation (OM talking about his job, his boss, his house, etc, some very information chatter).

Tuned in later on than normal this evening.  Heard these guys earlier today on 11 meters (27.695 MHz, etc).  They've since moved back down to their usual spot around 6.900 MHz / 6900 kHz.

Fair amount of storm static crashes and QRN tonight.  Usual "roundtable" net communications style often associated with this frequency.

10/11 meters / UK Remote SDR - European Europe 26 MHz 27 MHz 11 Meter Logs 30 May 2017

« on: May 30, 2017, 1825 UTC »

Starting at 1730 UTC.  WebSDR (technically, a KiwiSDR located grid IO80PW).  Clearly some propagation from Eastern Europe going on.  The 26 MHz region was interesting to look at on the waterfall.  Very organized use of 10 kHz steps and USB mode.  Once you get closer to the "mid band" or "CEPT" European band (26.965 to 27.405 MHz), things get a little crazier.  Basically, throw out the 10 kHz channel steps.  They're now 5 kHz steps.  Oh, and there's Russians EVERYWHERE. They're even having a casual QSO in USB mode on 27190 kHz, right next to the very busy 27180 and 27185 frequencies (Polish "zeros" frequency CB Channel 19 and EU/CEPT/EC channel 19)  No matter.  The area around 27.5 MHz is also nice and organized.  5 kHz steps, almost all USB mode, and stations that called CQ on 27555 USB then QSY to another nearby frequency.  

FM seems to be the main mode of choice, with some AM and USB thrown in for good measure.  The use of SSB appears to almost entirely be outside the legal frequency bands.  The UK FM 27/81 CB band 27.60125 to 27.99125 MHz (or 27601.25 to 27991.25 kHz) band was also busy, but I only logged a couple signals on the actual channels (of course, Russians using whatever frequency they want were also found in the 27.6 to 28 MHz area).

Lots of pagers and other data transmitters logged, and of course, the Italians on 27075 AM, 27465 AM and others.

10/11 meters / Re: 11m Activity 26 May 2017

« on: May 28, 2017, 1406 UTC »

27835 AM is an interesting one.  Usually when I hear AM signals (English speaking stations) they tend to stay below channel 1 (26965 kHz), with the big exception being truckers, hunters and poachers operating all over the bands.

For what it's worth, 27835 kHz / 27.835 MHz is channel 38 up one band (27385 + 450 = 27835).  Maybe they were having a QSO on 27385 and the QRM got too bad so they flipped that band switch.

10/11 meters / 11 Meter Band DX Opening Logs 22 May 2017 1600+ UTC

« on: May 22, 2017, 1825 UTC »

Another morning/early afternoon 11 meter 26 MHz 27 MHz band opening log, yes, here it is. 

Started monitoring around 1600 UTC May 22, 2017.  Lots of Latin American traffic, as usual, but the US frequencies of 26915, 27025, 27085, 27265, 27285 and 27385 were all active as well.  Our usual friends that hang around 27665 to 27705 were also booming in nicely, especially on 27695.  Did catch the tail end of a SSTV transmission on 27700 but haven't heard anything else since on that frequency, save for some very minor splatter from 27695 and 27705.

10/11 meters / 27505 kHz AM / 27.505 MHz AM Hunters or Poachers 1600-1745 UTC 22 May 2017

« on: May 22, 2017, 1751 UTC »

With all the other dozens of active frequencies in the 26-28 MHz range today, one of them sparked my interest, and that one is 27505.  This frequency is actually sporadically used in my local area as a "private" or "outband" (read: freeband) frequency for local AM CBers to get away from the usual crowd on their usual frequency (in this case, the frequency is 27125 / 27.125 MHz, or CB channel 14).

Anyway, I heard two OMs chatting on 27505 for well over an hour.  Topics included finding cover, hiding behind walls, and other things that made me think these stations weren't the usual AMers heard in this part of the band (often when AM traffic is heard above CB channel 40, its truckers).  Hunters usually hang out below CB channel 1, with some exceptions.  Judging by the topic of conversation, the fact that neither station had roger beeps, noise toys or anything else - indicating that they're using the radio for some practical purpose and not just for fun, I think they were either hunters or poachers.  An export radio or 10-meter radio is (along with a VHF radio of some kind, often a VHF marine radio or modified 2 meter ham radio) is often a requirement for a hunting club.  Modified 11 meter equipment is often synonymous with hunting radio.

FWIW, 27505 is CB channel 8 "up one band" (real CB channel 8 = 27.055 + .450 = 27.505).  I have a feeling these operators usually use 27055, but due to heavy QRM from 27025 and 27085 (both of which were booming in with massive overmodulated and splattering signals), they simply flipped the band switch up one band to get a clear frequency.  

I love these Sporadic-E openings.  You never know what you're going to hear.  Chances are the two stations I heard on 27505 were right next to each other.

10/11 meters / Data Link 27270 kHz / 27.270 MHz 22 May 2017

« on: May 22, 2017, 1733 UTC »

Just below CB Radio Channel 27 - 27.275 MHz / 27275 kHz.  11 meters equals 27.2727272... MHz so 27.270 is about as close to exactly 11 meters as you can get.  Anyway....

I have often logged paging and other data link signals on 27255 kHz / 27.255 MHz (CB channel 23) but never on 27270.  It's possible this is coming from outside the US, given the large amount of international, specifically Latin American,DX traffic heard during today's band opening on 27 MHz.  Fair amount of domestic (US stations) heard all around the band as well.  

The band has been opening most of the morning into the early afternoon (it is currently 1330 local time, 1730 UTC).  First noticed data link around 15-20 minutes ago and it has been on and off ever since.  Strong, often overmodulated signals on 27265 (CB channel 26) and 27285 (CB channel 28).  Sounds like FSK signal to me, often S9+ so very strong.

10/11 meters / 27025 and 26715 insanity 22 May 2017

« on: May 22, 2017, 1617 UTC »

Hearing wall-to-wall overmodulated signals on 26705 (Spanish language) and 27025 (English language, if you could call it "English").  Some of the signals on 27025 are so terribly overmodulated and distorted that I can't understand anything.  S9 all day long, up to S9+30 or more. 

Watching on the waterfall, some of these channel 6 superbowl signals 27.025 MHz are 40-50 kHz wide.  I feel sorry for the stations trying to talk on 27005 or 27035.
