Solid S9.  Top notch signal, armchair copy of "Lucky Man" in progress at 0101 UTC

Scorpions - Wind of Change at tune-in (0135 UTC)

Somebody forgot to turn the "template" feature off in MMSSTV  ;D

John Couger - Jack and Diane here solid S9 signal through the local QRN.

Love the cat theme! 

10/11 meters / Re: Different Language QSO'S on 25.845 LSB

The majority of "export" radios (also sold as "10-meter" radios but are switched "converted" down to 11-meters through a simple set of button pushes or another simple modification) cover considerably more frequencies below the 10 meter band allocation than they do above the 10-meter allocation.  The "standard" export radio frequency plan is six sets of 40 channels, 25.615-28.305 MHz.  I've heard of some of the newer radios going up to 30.105, 30.555 or even 31.005 MHz.  You'll notice each set of 40 channels is the same bandwidth as the legal CB band (450kHz).  Of course, some radios go below 25.615, usually down to 25.165 but some of them go down into 12 meters or even below, 24.715 or even 24.265 MHz.  

The two export radios I use, a Voyage VR9000 (a.k.a. Galaxy 88, Superstar 3900F/3900EFT, Super Jopix 2000, and a dozen others - of course they're all made by Ranger/RCI) covers 25.615-28.305 MHz.  My CRE 8900 covers up to 30.105MHz but I see no point in going above 10 meters when there's plenty of empty channels below 28.000 MHz.

So therefore, you're looking at people running exports on band "A" (assuming the legal CB band is band "D" - as it usually is), channel 19A - 27.195MHz "down three bands".  So that means the radios they're using have that lovely +10kHz switch, allowing you to get to the "A" channels (26.995, 27.045, 27.095, 27.145 and 27.195 MHz).  So each band really has 45 channels and not 40 channels.  I've heard truckers on 25.835 MHz plenty of times (band A, channel 19).  Makes sense don't it?  Just flip that band switch down to band A, I feel bad for these trucker's radios, I'm yet to hear of a CB antenna that can do 27.185MHz and 25.835MHz with a decent SWR.  You know these guys aren't adjusting their antennas when they move up and down the freeband.  

Hearing SSB transmissions below 27MHz is uncommon though.  Most of the stuff below CB channel 1 [26.965 MHz] I hear is in AM mode, and I'd say 3/4 of the transmissions I've heard above CB channel 40 [27.405 MHz] are in SSB mode.  Of course, there's some AM above channel 40, usually in the form of truckers flipping their bandswitches up to get away from the noise of the legal 40 channels.  Interesting to see SSB below channel 1.  I've noticed it on 26.500, 26.515, 26.540 and 26.555, all LSB..but below 26MHz is a new one for me.

It seems like there's a "gentleman's agreement" on the freeband, as much as hams (especially the QRZ or eHam forum types ;)) would hate to hear something like that.

Could it have been some sort of jamming system? 

I could see IEDs and other remote-control bombs using the 26-28 MHz band, considering how many R/C frequency allocations there are there (and in the 29MHz, 30MHz, 31MHz, 35MHz and other "high-HF" and "low-VHF" bands).

« on: May 07, 2013, 2100 UTC »
I hear it (26485) when the band is open, especially to Mexico/Latin America.  Only in LSB and CW mode.  There's similar activity around 27.650 MHz. 

27.650 is almost always there.  Was wondering if anybody else on the east coast of the U.S. (or anywhere really) could also hear these signals.

I'm interested in what military/government use of the 25-28 is still in existence, even the proliferation of export radios to the point of every 5-10 kHz from 26.5 to 28 has signals on it during a good band opening.

RIP Storm.

Wish You Were Here is one of the greatest album covers of all time.  Dark Side of The Moon is iconic.

Nice.  I've never seen a STL outside of the usual 25910, 25950 and 25990 either. 

Next time you hear STLs around the top of 25MHz and the bottom of 26MHz, look for taxicab dispatchers in AM as well.  I've seen them as low as 25.615 MHz.

10/11 meters / Re: Irish Churches 11 meters 1750 UTC

Interesting that a lot of these seem to be on random frequencies.  Ireland's Wireless Public Address System (WPAS) service offers two sets of frequencies and the option of AM or FM modulation.  While the logs on 27.xx0 and 27.xx5 make sense, there's signals on 27.637 and 27.688 and whatnot.

The WPAS system allows operation on 10kHz spaced channels from 27.605 to 27.995 (no gaps, AM or FM allowed) and 27.60125 to 27.99125 (no gaps, AM or FM allowed).  The 27.60125-27.99125 allocation is the same as the UK 40 channel FM CB "27/81" allocation and would explain the signals on 27631, 27650, 27680, 27742, 27810 and 27890 kHz.  Have all of these been FM that you've logged?  Maybe these churches are really just picking a frequency between 26 and 28 MHz and going with it.  The 27506 kHz one isn't even a legal frequency for WPAS or CADS

(and yes I know this is an old thread I just thought I'd share the information about the WPAS (and whatever the UK version is - Community Audio Distribution System / CADS - which appears to only operate in the 27.60125 - 27.99125 allocation with FM mode only, legally speaking anyway).

The RCI-2900 is apparently a very nice radio.

You should take it out of storage while the cycle is still active :D

Hey all,  I know in Europe they have a big problem now with Russian/CIS/former USSR taxicab interference on the CB/11 meter freeband and in the bottom of 10 meters.  

The same thing is now happening in North America (at least at my QTH in Richmond, VA).  When the band is open to the south not only can I hear taxicab dispatchers in NFM using 10 or 20 kHz spacing above 30.000 MHz, up into 31 and 32 MHz, with domestic U.S. business band skip... (I've even seen them on 30.115 MHz, AM, I assume that's using CB gear and not land mobile lowband gear because the NFM activity all has CTCSS tones).  

This part of listening to 11-meters really interests me.  My Spanish is not that great but its easy enough to figure out that what you're listening to is taxi dispatchers (or at least another kind of business radio system) vs. just regular freebanders/outbanders/pirates/CB bandits or whatever you wanna call em.  I've noticed that they tend to hang out in the lower parts of the de-facto "11 meter bands" so band A on most exports is either 25.165 - 25.605 MHz or, more commonly, 25.615 to 26.055 MHz.  There's been points where I could hear activity (all in AM save for STLs on 25.990 and 25.910, I bet they're glad they're not using the .xx5 MHz step!) every 10kHz from 25.615 to 26.055, including the "A channels").  Some of these newer exports no longer just cover 25.615 to 28.305 MHz anymore.  Some of them go above the top of 10-meters and into the 30MHz band (keeping the CB-like channel plan of course).  I'm pretty sure the Magnum S9 can go up to 32.990 MHz and down to below the 12-meter band.  Obviously the radio needs to be tuned for the band in question.

Another interesting frequency commonly used appears to be 27.515.  Channel 9 is very popular for some reason, CH9 in the legal band is 27.065 and is nothing but Puerto Rico, CH9 "down one band" is 26.615 and that's another really popular AM calling frequency (see also, 26.585, 26.595, and 26.605) but CH9 "up one band" is 27.515 which is also the Caribbean LSB DX frequency.  Many times I've heard an AM taxi cab dispatcher completely obliterating the high power stations from Jamacia on 27.515 LSB.  Has anybody else experienced this?  

Is it strange that people using 11m for business radio communications needs is one of the things that I consider interesting about this band?  ;)

Thanks for the reply!

Apparently all (or most) of these Ranger/RCI manufactured rigs are clones of the original Cobra 148 with features added or subtracted.  Apparently they did make versions of the 148 with extended frequency coverage and the 27.60125 to 27.99125 UK CB band (some with just one band down and one band up so 26.515 to 27.855 and another one with something like 24-30 MHz coverage so you could do 12 and 10 meters in addition to CB and freeband.)  Ranger/RCI makes pretty much every export out there (Galaxy, Superstar, Connex, General, Voyager, the list goes on), interestingly enough.

I used to use a homemade dipole (I live in a duplex and I'm a renter, graduate student) and that really got out.  It was facing North-South so I got a lot of Spanish language taxi cab traffic as well as DX from Europe.  I love hearing the UK CBers on their channel 19 (27.78125) when the band is open.

Hello all,

New to the board, interested in its 10/11 meter board but wanted to post here since this section deals with equipment.  I like to focus my monitoring on the 11-meter "freeband", including taxicab dispatch DX and STLs.  I am currently running a CRE 8900 mobile and a Ranger Voyage VR9000 (Superstar 3900 clone with a frequency counter). 

I'm wondering what the other 11-meter guys on this forum are using for monitoring.  My main antenna is a NMO mounted base loaded quarter wave land mobile antenna cut for 27.5 MHz.
