There's a lot of truckers using Channel 29 FM 27295 kHz.

Have they been using FM on Channel 29 for a while now?  Or is CB channel 29 FM a new thing like 26.805 MHz FM? 

I kinda like it - CB Channel 19 AM, Channel 29 FM.  Makes sense to use 27.295 MHz (channels 27 and 31 also make sense - in-between the "big radio" channels 26/28 27.265 MHz AM and 27.285 MHz AM) for FM CB. 

Glad to see the surprisingly rapid adoption of FM. Since there's a vast installed equipment base capable of FM mode already out "in the field" the switchover from AM/SSB to AM/FM/SSB CB radio / 11 meters is already happening. 

For short range comms, FM provides superior audio quality and rejection of noise/static.  When dealing with weaker signals, AM has some advantages but SSB is the obvious winner in those situations.

I had included 27.315 FM CB channel 31 - 27.315 MHz FM as the FM CB calling channel since CB channel 31 FM is one of the European in-band FM calling channels, I would call it the European version of 27.385 LSB channel 38 LSB but for FM mode specifically and for calling specifically. FM is the "default" mode for CB in many European countries so the situation is reversed. 

In the UK, for example, AM has only been legal on the FCC 40 CB channels or mid band CB or CEPT/EU standard 26.965-27.405 MHz band for the past 10-15 years.  SSB was legalized even later.  On the UK specific UK FM CB 27/81 channels 27.60125 MHz - 27.99125 MHz, FM is the only mode permitted and that probably won't change. 

Most European countries permit AM on the standard 40 CB channels in addition to FM (and most of those allow SSB as well) but this is somewhat recent of a development.  Now basically all CB rigs sold in Europe are AM/FM at least.  In many ways, the FCC legalizing FM on CB is sort of things coming "full circle".  AM will still be the standard mode for US CB radio - SSB and FM are now the extra-feature modes but I can see FM-capable FCC approved CB equipment entering the US market rapidly.

At 1325 UTC, noted faint pager signal activity on 26.900 MHz 26900 kHz on the W3HFU KiwiSDR (11 meter dipole).  26.9 MHz is a known active European 26 MHz paging frequency.

Maybe a bigger opening today or some Sporadic-E activity.

Here is a list of active paging and telemetry frequencies - all European in origin.  All frequencies are confirmed as active as of October 2021.  Many of these systems transmit an "idle" signal every 2-10 seconds, even if no data is being sent.  Others only transmit when needed. On the more active 26 MHz frequencies, several different signals may be noted on the same frequency.



Based on listening on several European SDRs:


26150 kHz 26.150 MHz - European paging, hospital pager data telemetry - POCSAG and other modes

26645 kHz 26.645 MHz - European paging, hospital pager data telemetry - POCSAG and other modes
26650 kHz 26.650 MHz - European paging, hospital pager data telemetry - POCSAG and other modes
26655 kHz 26.655 MHz - POCSAG - narrow - noted in mainland Europe
26670 kHz 26.670 MHz - POCSAG - wide and narrow

27400 kHz 27.400 MHz - POCSAG and other data modes
27450 kHz 27.450 MHz - POCSAG and other data modes


The European standardized or harmonized 26 MHz paging band extends from 26.200 MHz to 26.935 MHz or 26200 kHz to 26935 kHz (according to several sources). 

Others indicate that the band extends from 26.175 MHz to 26.950 MHz or 26175 kHz to 26950 kHz.  The 26.995, 27.045, 27.095, 27.145 and 27.195 frequencies are standardized throughout Europe for model control telecommand radio control RC use.  The standardized 27 MHz ISM band (center frequency 27.120 MHz 27120 kHz +/- 163 kHz for a frequency range of 26.957 MHz to 27.283 MHz / 26957 kHz to 27283 kHz) also applies and the same range is permitted for very low power short range devices - nonspecific SRDs.

The table of frequency allocations breaks the bands down as follows:

26100 kHz - 26175 kHz 26.100 MHz - 26.175 MHz - Maritime Mobile - DSC, marine HF radio, military communications

26175 kHz - 26200 kHz 26.175 MHz - 26.200 MHz - Fixed and Mobile - Fixed service, military mobile

26200 kHz - 26350 kHz 26.200 MHz - 26.350 MHz - Fixed and Mobile - Fixed service, military mobile

26350 kHz - 27500 kHz 26.350 MHz - 27.500 MHz - Fixed and Mobile - CB radio (EN 300 433 band 26.96-27.41 MHz)

27500 kHz - 28000 kHz 27.500 MHz - 28.000 MHz - Fixed, Mobile, Meteorological Aids - Military mobile communications systems, including aeronautical military systems, land mobile military systems

10/11 meters / Re: 11 meters 26 OCT 2021
« on: October 27, 2021, 1121 UTC »
Not sure of the specs on freq. Quite an amazing radio though. Never heard of anything else like it. I had forgotten about the Cherokee. I knew there was another one. Back when things were really hot on 10/11, as I remember 96- 2001? you could have totally worked DX with it, if you had a decent antenna. And by decent, I don't mean a Yagi or anything. A 1/4 or 1/2 wave would have done the job. Depending on the particular day.

Those were the days.

I remember in 2000 or 2001 hearing California Highway Patrol on 42 MHz and hearing UK military traffic in the 30-32 MHz region (as well as US military traffic in the same region) along with various car services and taxi dispatchers in the same 29.7-50 MHz low band region - but especially the 30.580 MHz to 31.980 MHz and 35.020 MHz to 35.980 MHz business/industrial land mobile bands (for the car service dispatchers out of New York City and other business users nationwide). 

On really good days I could hear the low band military, police on 39 MHz/42 MHz and business users along with various 10 meter FM repeaters using a handheld RadioShack Pro-79 scanner with the stock rubber duck antenna.  That particular scanner's coverage stopped at 29.000 MHz and from 29-54 MHz it was FM mode only.  Still, nuts to hear all the things I did with the cheapo factory rubber duck antenna.

A actually have the Cherokee AH-100 SSB HT of that same Magnum portable. More of a concept portable really, since various features are limited in performance, but still a neat radio. Just, don't try and drive and operate with one. (Hi-hi...)

I know an op who has/had one of the Magnum 1012 handhelds and he had nothing but good things to say about it.  My experience with Magnum radios is, on the other hand, meh (but it involved one of their mobile rigs, not handheld).  I would love to have a HT with AM/FM/SSB vs. just AM.  Also access to the whole 11 meter/10 meter band - ideally the "full" 25.615 MHz to 30.105 MHz coverage...I believe the 1012 actually covered 24-30 MHz?  Somebody correct me if I'm wrong, I'm too lazy to look up the specs.

I did several range testing sessions with another station who was using a Magnum 1012 HT, both with telescopic CB/11m whip antennas and with the HT connected to mobile CB antennas (namely a Wilson 5000).  The Magnum 1012 worked really well on AM, FM and SSB (we tested all modes except CW while mobile...)

The Uniden PRO401HH is a real utilitarian 40 channel handheld.  With the Cobra HA-TA telescopic antenna it actually is a serviceable handheld CB, albeit very bare bones.  It does what it is designed to do.  I've talked to several local operators and nearby truckers on channel 19 on it on the low power setting (roughly 1 watt AM carrier according to my rather conservative reading wattmeter). 

I wouldn't mind getting my hands on a pair or even 3-4 of the Midland 75-822 handhelds, they can apparently be modified rather easily to cover the low/high bands in addition to the legal 40 CB channels - expanding coverage from 40 channels to 120 channels (26.515 MHz - 26.955 MHz low band / 26.965 MHz - 27.405 MHz mid band / 27.415 MHz - 27.855 MHz high band).  I know of at least one CB shop that sold the Midland 75-822 handhelds with companion mobile rigs (Superstar 121 radios to be exact - since the Superstar 121 is a bare-bones AM/FM export radio that also covers the same low/mid/high 26.515 MHz - 27.855 MHz band).  Pretty cool idea.

Of course, having FM and SSB would be much nicer.  It's still a cool concept though.

Tuned in to hear the very tail end of

"...PAPA on frequency eight thousand...how copy? over"


I know that the frequency 8000 kHz is part of the larger 7300 kHz to 8195 kHz fixed/mobile allocation (yes, I know the lower portion is heavily used by broadcasting and other things and 8000 kHz to 8195 kHz is a shared allocation with maritime mobile / marine mobile radio service - usually simplex operations...)

Could have been a marine operator?  Sounded very professional, more like military or similar.  Have been sitting on frequency for 5 minutes or so and haven't heard a peep after the "how copy? over." transmission

Walking around on my lunch break with my Uniden PRO401HH bare bones 40 channel AM only handheld CB walkie talkie - and telescopic CB antenna - Cobra HA-TA aka HT-1 antenna...able to hear what sounds like truck stop advertisements on channel 19 27.185 MHz AM...along with a real mess on channel 5 27.015 MHz AM and a taxi dispatcher lady coming in nearly SIO 555 with very little QRM on CB channel 18 - 27.175 MHz AM.  Pretty impressive considering the receiver I'm using and the high levels of ambient RF noise and interference...

Hearing South Texas, California and other stations right now - 1556 UTC anyway on 26805 FM - 26.805 MHz FM.  Strong station in TX talking about having to QSY from 27.555 USB and 27.385 LSB due to heavy QRM.  Very good signals at points.

10/11 meters / Re: 11 meters 26 OCT 2021
« on: October 26, 2021, 1330 UTC »
First tuned in at 1330 UTC - this is on the W3HFU KiwiSDR - the one with the 11 meter dipole antenna.

Some SSB activity on CB channel 36 LSB 27.365 MHz LSB, some AM voice on channel 40.

Somebody doing radio checks on CB channel 31 AM 27.315 MHz AM at 1330 UTC.

Truckers or other business type comms now on CB channel 1 26.965 MHz AM - 1332 UTC

"I'll take the 2A..." "doesn't have to be this route" "yeah, yeah, just bring that ticket down and we'll switch it out when you get back or when you get back down this way...another line is coming back up this way"

"they waited for all the rain and now they want off?"

CB channel 1 seems to be a local business user channel, at least at the moment. 

At 1334 UTC, switched up to CB channel 19 AM 27.185 MHz AM...sounds like local trucker and highway traffic (as to be expected on 27.185 MHz).  Noted signals coming in on 27.025 and 27.085 as well as 27.065, possibly indicating a band opening may be in the works for today. 

1336 UTC - series of FSK bursts started up on CH 23 - 27.255 MHz - continued for about 90-120 seconds, ended with four bursts in very rapid sequence.

27.255 MHz FSK AFSK Data Bursts Datalink Part 95 Subpart C RCRS CB Channel 23 Telemetry Telecommand

1353 UTC - the same FSK bursts that were noted about 20 minutes ago on frequency 27255 - appears to be the same system (same waveform on the waterfall display, same FSK characteristics - I guess its AFSK or audio frequency shift keying).  I was able to get a quick video of the previous FSK data link signal data bursts on 27.255 MHz and that's on YouTube. There is no audio unfortunately.  See video link above

10/11 meters / 27.815 MHz Taxi Dispatcher Mexico City DF Mexico
« on: October 25, 2021, 2217 UTC »
Huge band openings lately - tons of taxi dispatchers from 25.615 MHz up through the legal 40 CB band into the uppers 27.415-27.855 MHz and the 27.865 MHz - 27.995 MHz region.

27815 AM 27.815 MHz Spanish lady reading numbers is a taxi cab dispatcher radio dispatch taxi controller - confirmed in Mexico City Mexico DF Mexico.  Useful point of reference when the band is open and the activity on 27.815 mhz is there.  Also our friends on 25.695 MHz 26.105 MHz 26.175 MHz 26.765 MHz 27.215 MHz 27.235 MHz 27.245 MHz 27.255 MHz 27.275 MHz 27.755 MHz 27.765 MHz 27.775 MHz 27.785 MHz 27.825 MHz and others are coming in.

This is a good ballpark point of reference for when 11 meters is open.  Similar to, say, 26.585 MHz AM and nearby frequencies like 26.595 MHz 26.565 MHz etc

1908 Starting to get some Latin American DX now. In addition to the usual stuff, I have some on channel 7 in FM mode. Earlier this morning I heard a local on channel 12 in FM mode.
1918 27440 FM now also
1932 I thought 26575 was FM, but it's actually AM with a lot of FMing. Maybe he has the prototype Stretchyman® CB rig  :P
1934 I saw what looked like an RC signal of some sort on channel RC-3A
1943 Quite a mix on 38L, Jamaica, Oregon, and more.

That RC signal came back, here's a picture:




FM also on 27.125 MHz earlier.

That signal on 26.995 looks like numerical POCSAG.  Heard all over 11 meters...including on oddball offset frequencies like 27.007 MHz or 27.888 MHz or 27.838 MHz or 27.272 MHz.
