VHF/UHF Logs, including satellites and radiosondes / Re: UK Hospital Pagers 31.725 MHz / 31.750 MHz / 31.775 MHz

« on: December 20, 2022, 1531 UTC »

As a follow up to this - the band is open again today, and I'm hearing faint POCSAG signals on 31.7250, 31.7500 and 31.7750...fading up out of the noise a tiny bit right now (1530 UTC) on 20 December 2022.

The 11m band is wide open the Europe, the UK and Latin America right now so it makes sense.

VHF/UHF Logs, including satellites and radiosondes / Re: Fort Hood, Texas Range Control 30.450 MHz FM 30.45 FM - 9 November 2022

Awesome logs - and reference frequencies.  It's pretty cool how much use they make of the 54-88 MHz frequencies, especially the 60 MHz and 70 MHz region, which I imagine is pretty darn clear now.

Also, that antenna is kickass.  30-88 MHz.  Love it.  Reminds me of a discone design. 

There seems to be a lot more usage of 30-88 MHz (or even just 30-50 MHz) than you'd think.  I often read the RadioReference.com forums (there's a nice long VHF low band logs thread, one per year, keeps things nice and searchable) and there is a lot of VHF low band military activity, especially in the lower portions (below 35 MHz or 40 MHz or so..although the 40-42 MHz band is the biggest chunk of military/government frequency allocation within the 30-50 MHz low band).  Lots of 30 MHz, 31 MHz, 32 MHz, 34 MHz and random frequencies that are within the land mobile bands.

10/11 meters / Re: 11m Band Activity 19 DEC 2022

« on: December 19, 2022, 1514 UTC »

Sounds like another excellent opening.

I heard a fair amount of UK FM CB chatter (especially on channels 6, 19, 38, 39 and 40 - so 27.651 FM, 27.781 FM, 27.981 FM and 27.991 FM).  Noted POCSAG activity on 27.450 MHz, 27.650 MHz, 27.700 MHz, 27.750 MHz and multiple data/pager signals around 27.85 MHz (offset frequency, 27.846 MHz or 27.847 MHz). 

The usual UK 26 MHz band paging frequencies were also alive - 26.695 MHz, 26.700 MHz, 26.705 MHz, 26.745 MHz, 26.750 MHz MHz, 26.755 MHz...with Spanish language taxi dispatchers mixing in (26.765 MHz AM had a very good signal over the weekend, YL taxi dispatcher).  Taxis active on 27.785 AM while UK FM came in on 27.781.25 FM.  European pagers booming in on 26.800 MHz, 26.850 MHz, 26.900 MHz, 26.950 MHz and 27.300 MHz.  UNID data signals on 26.940 MHz, 26.945 MHz, 26.950 MHz, 26.955 MHz, 26.960 MHz...

UK hospital paging active on 31.725 MHz, 31.750 MHz and 31.775 MHz as well.  Strangely, the 29 MHz frequencies seemed quiet.   27.975 AM with Spanish language OM chatter.   Fair amount of AM signals in the lower portions of 10 meters (CBers in 10 meters), namely 28.005 AM, 28.035 AM, 28.055 and many other frequencies, up to 28.235 MHz.

Lots of interesting UNID signals in this band, CB is not dead!

An interesting note regarding French language chatter, I've noticed that French chatter seems to pop up in the upper reaches of the 25.615 MHz to 30.105 MHz coverage of most export rigs, especially in the 27.9 MHz to 28.0 MHz region, including 27.995 MHz USB, 27.997 MHz LSB, and 29 MHz band frequencies, namely 29.775 MHz AM, 29.815 MHz AM, 29.825 MHz AM, 29.875 MHz AM, 29.905 MHz AM, 29.915 MHz AM, 29.925 MHz AM and 29.975 MHz AM.  The 29 MHz AM signals all sounded like freeband CBers - but the language was only French. That, or its a land mobile user (legit, licensed user).  Probably not though, considering use of AM mode.  Another interesting indicator are the 29 MHz pagers - 29.750 MHz, 29.800 MHz, 29.850 MHz, 29.900 MHz, 29.950 MHz.  Canadian hospitals are still found on 30.020 MHz (and others).

10/11 meters / Re: 11m Band Activity 16 DEC 2022

« on: December 16, 2022, 1857 UTC »

It's been going nuts.

I'm currently listening to what sound like truck drivers (Spanish speaking) on 28005 AM. 

I'm sure these land mobile users are operating in 10 meters all the time, but now they're actually coming through.  Lots of taxi cab comms on 25 MHz, 26 MHz and 27 MHz as the propagation shifts from the UK and Europe to Latin America

Recent logs:

28.235 MHz AM - taxi dispatcher (Spanish language)
28.205 MHz AM - taxi dispatcher (Spanish language)
28.085 MHz AM - truckers - English language
28.055 MHz AM - taxi dispatcher (Spanish language)
28.035 MHz AM - taxi dispatcher (Spanish language)
28.025 MHz AM - taxi dispatcher (Spanish language)
28.005 MHz AM - multiple stations at once, hearing OMs and a YL taxi dispatcher


Some other oddities:

27.975 MHz AM - group of US truck drivers using export radios, most of which are in serious need of an alignment - carrier frequencies noted below:

27.974.1 MHz
27.976.0 MHz
27.977.9 MHz
27.975.3 MHz
27.975.8 MHz



27.385 MHz LSB - as to be expected, then somebody playing music (in FM mode) on top of the SSB traffic - CB Channel 38
27.255 MHz dozens of different data signals, with AM and FM voice (mostly AM) mixing in
27.207 MHz - Another odd FSK signal, center frequency might be closer to 27.208 MHz
27.205 MHz FM - Lots of FM signals on top of each other - CB Channel 20
27.205 MHz AM - AM and FM and SSB, the area around 27.2 MHz / CB Channel 20 is really messy
27.201 MHz USB - Spanish language, very good signals
27.198 MHz USB - center frequency 27.199 MHz - narrow band FSK data signal, 2.5 kHz wide
27.195 MHz MFSK - constant multiple-carrier frequency shift keying data signal, about 6.5 kHz wide
27.195 MHz MFSK - the constant signal faded away, now a rapid burst signal is on the frequency (with AM voice traffic)
27.195 MHz AM - taxi dispatch lady (Spanish language)
27.195 MHz AM - "Can you copy the radio?" (English, very good signal)
27.095 MHz - Yet another unique data signal, bursts every few seconds, FSK, about 5 kHz wide
27.095 MHz AM - another taxi dispatcher - YL speaking Spanish
27.000 MHz USB - Weak voice traffic noted
26.995 MHz MFSK - Very similar signal to the one noted on 27.195.  The 27.195 MHz MFSK data signal is a good indicator of the band being open to Latin America
26.995 MHz AM - Hearing OMs talking, does not sound like a taxi or other business or land mobile user
26.995 MHz AM carrier, 26994.5 kHz zero beat

Peskies / Re: Russian Freebanders or Fishing Fleets Around 3 MHz - 17 October 2022

« on: November 18, 2022, 1420 UTC »

kris,

Thank you very much for the insight regarding these operators.   I figured they were either outbanders (bootleggers, freebanders) and/or were guys using old AM mode marine or military equipment with analog frequency displays in the 2-3 MHz region. 

It makes sense given that a large number of World War II transmitters or combined transmitter-receiver sets operated in that (roughly) 2-4 MHz range (lots of equipment only covered the higher bands, like 3.8 MHz to 6.5 MHz or so).  The older-generation marine radiotelephone equipment also worked in that similar range (1.6 to 4 MHz or 2-4 MHz), with some transitional-generation gear having the capability to run in "AM equivalent" or "AME" mode (SSB with a carrier so an AM only receiver could demodulate their signal, but somebody with their radio set to USB mode could also talk to them). 

These transmissions are very easily heard using internet SDR receivers located in Poland and other locations in Europe, but, understandably so, they are very strong on receivers in Poland, Ukraine and Russia (this was pre February 2022 in the case of the Russian and Ukrainian KiwiSDRs). 

100 meter band.  I like the sound of that.  100m is 3 MHz or 3000 kHz.

VHF/UHF Logs, including satellites and radiosondes / UK Hospital Pagers 31.725 MHz / 31.750 MHz / 31.775 MHz

« on: November 15, 2022, 0157 UTC »

With the recent band openings, I've done some research and in addition to the dozens upon dozens of pagers in the 26-28 MHz band and 29.7-30 MHz band, the UK use

31.725 MHz
31.750 MHz
31.775 MHz

and I've noted POCSAG signals on 31.75 MHz with just a handheld scanner and a telescopic antenna (CB/11m/10m base loaded antenna, roughly 50" long fully extended). 

Looking forward to more band openings on 11 meters, 10 meters, the VHF low band and 6 meters.  Lots of interesting signals in the 26-28 MHz, 29.7 MHz to 30 MHz and 30-50 MHz low band coming out of the UK, Europe, Latin America...

10/11 meters / Re: What Is Freeband 11 Meter Free Band CB Radio Export Radio Info

« on: November 14, 2022, 1950 UTC »

Yes! 40 channels 26.965 to 27.405 MHz (listed one by one) plus a continuous allocation 27.415 MHz to 27.855 MHz, which usually are stepped every 5 kHz by the freebanders.

I'm glad to hear they've opened that spectrum up for regular AM and FM use as well as 5 kHz step SSB freebander use. 

The 25.615 MHz to 27.995 MHz band is de facto CB here in the USA, especially the "lowers and uppers" or "120 channels" (26.515 MHz to 27.855 MHz).  The lower frequencies (Band A and Band B - that is, 25615 to 26055 and 26065 to 26505, are still very popular with hunt clubs, trucking companies, logging companies, farmers, etc.  A basic AM/FM 360 channel mobile radio (like a Connex 3300 or similar rig) and now the Chinese rigs - are very popular.

10/11 meters / Re: What Is Freeband 11 Meter Free Band CB Radio Export Radio Info

« on: November 14, 2022, 1534 UTC »

In Greece, since December 31, 2021, freebanding is legal !

Accrding to the current frequency allocation tables, CB radio uses the regular 40 US channels: 26965 - 27405. In addition, CB is allocated on a secondary basis 27415 - 27885 kHz without channelization !

Awesome.  So Greece currently has...80 channels?  26.965 MHz to 27.855 MHz?  Or Band D + Band E?  Or is it just 26.965 MHz to 27.405 MHz (40 channels) + 27.415 MHz to 27.855 MHz (or 27.885 MHz?) in de facto 5 kHz steps? 

Pretty cool either way.    Seems like this is the direction many countries are taking:

UK has 80 channels - 40 standard EU or CEPT "mid band" or US CB channels 26.965 MHz - 27.405 MHz (AM/FM/SSB permitted) + the 40 UK FM "27/81" channels (FM only) 27.60125 MHz - 27.99125 MHz

Germany, Austria, Hungary, Czech Republic have 80 channels - 40 standard EU or CEPT "mid band" or US CB channels 26.965 MHz - 27.405 MHz (AM/FM/SSB permitted) + 40 additional channels 26.565 MHz to 26.955 MHz (straight 10 kHz channel steps, no skips, with 26.565 MHz being Channel 41, 26.575 MHz being Channel 42, up to 26.945 MHz being Channel 79 and 26.955 MHz being Channel 80).  Channels 41-80 are FM mode only (or FM like data modes, FSK, AX.25 packet radio, etc.) 

Russia has two sets of 120 channels

The European band plan or "raster" - the "fives" with the channel frequencies ending in 5

26.515 MHz to 26.955 MHz - Band B
26.965 MHz to 27.405 MHz - Band C - standard CB band
27.415 MHz to 27.855 MHz - Band D

And the Polish band plan/original Russian band plan or "raster" - the "zeros", identical to the standard CB radio channel plan but -5 kHz so

26.510 MHz to 26.950 MHz - Band B
26.960 MHz to 27.400 MHz - Band C - standard Polish zero raster CB band
27.410 MHz to 27.850 MHz - Band D

It's easy to see "Band A" - 26.055 MHz to 26.505 MHz and 26.050 MHz to 26.500 MHz

The band identifiers are sometimes moved "up one" (to match the standard A-B-C-D-E-F band 25.615 MHz - 28.305 MHz export radio band plan).

Russia effectively has 5 kHz steps.  Channels are given an alphanumeric designation to indicate

Band (B, C, D)
Channel (1-40)
Band Plan (Zeros or Fives) or Channel Raster - European (standard) is "E" and the Polish CB channel plan is "P"
Mode - A for AM mode or F for FM mode (some radios show AM for AM mode and FM for FM mode)

So

27.185 MHz AM would be Channel C19EA or Channel C19EAM or Channel C19E AM

27.180 MHz FM would be Channel C19PF or Channel C19PFM or Channel C19P FM

27.635 MHz FM would be Channel D19EF or Channel D19EFM or Channel D19E FM

The skipped "A" channels (RC and data channels) are also heavily used.  Radios sold for that market will have a +10 kHz switch and a -5 kHz switch.  This means that the top frequency 27.855 MHz actually is 27.865 MHz (or 27.860 MHz) because you could go to Channel 40 on the high band and then flick the +10kHz switch.
 
Confusingly, these have an "A" added to them (3A, 7A, 11A, 15A, 19A) for the three bands:

European channel plan

Channel B03A - 26.545 MHz - Channel 3A "down one band" (on regular export radios, this would be Band C, Channel 3A) - on the "zero" raster - 26.540 MHz
Channel B07A - 26.595 MHz - Channel 7A "down one band" (on regular export radios, this would be Band C, Channel 7A) - on the "zero" raster - 26.590 MHz
Channel B11A - 26.645 MHz - Channel 11A "down one band" (on regular export radios, this would be Band C, Channel 11A) - on the "zero" raster - 26.640 MHz
Channel B15A - 26.695 MHz - Channel 15A "down one band" (on regular export radios, this would be Band C, Channel 15A) - on the "zero" raster - 26.690 MHz
Channel B19A - 26.745 MHz - Channel 19A "down one band" (on regular export radios, this would be Band C, Channel 15A) - on the "zero" raster - 26.740 MHz

Channel C03A - 26.995 MHz - Channel 3A (on regular export radios, this would be Band D, Channel 3A) - on the "zero" raster - 26.990 MHz
Channel C07A - 27.045 MHz - Channel 7A (on regular export radios, this would be Band D, Channel 7A) - on the "zero" raster - 27.040 MHz
Channel C11A - 27.095 MHz - Channel 11A (on regular export radios, this would be Band D, Channel 11A) - on the "zero" raster - 27.090 MHz
Channel C15A - 27.145 MHz - Channel 15A (on regular export radios, this would be Band D, Channel 15A) - on the "zero" raster - 27.140 MHz
Channel C19A - 27.195 MHz - Channel 19A (on regular export radios, this would be Band D, Channel 15A) - on the "zero" raster - 27.190 MHz

Channel D03A - 27.445 MHz - Channel 3A "up one band" (on regular export radios, this would be Band E, Channel 3A) - on the "zero" raster - 27.440 MHz
Channel D07A - 27.495 MHz - Channel 7A "up one band" (on regular export radios, this would be Band E, Channel 7A) - on the "zero" raster - 27.490 MHz
Channel D11A - 27.545 MHz - Channel 11A "up one band" (on regular export radios, this would be Band E, Channel 11A) - on the "zero" raster - 27.540 MHz
Channel D15A - 27.595 MHz - Channel 15A "up one band" (on regular export radios, this would be Band E, Channel 15A) - on the "zero" raster - 27.590 MHz
Channel D19A - 27.645 MHz - Channel 19A "up one band" (on regular export radios, this would be Band E, Channel 15A) - on the "zero" raster - 27.640 MHz

Heard locally (using a handheld scanner!) and via the N1NTE KiwiSDR.

POCSAG bursts on 31.75 MHz 31,750 FM 31.750 MHz FM.  Fading in and out.  Known use in Europe.  12.5 kHz steps...but right now 31.75 MHz seems to be the active one (or the strongest one).
