FREEBAND 11 METER FREQUENCIES AND BANDS
While some export radios – sold as 10 meter radios – often cover frequencies above and below the 25.615-28.305 MHz range, that is the de facto “standard” export band alphanumeric plan. Generally the CB band is band “D” or the “mid band”. On 120-channel radios, coverage is generally limited to 26.515-27.855 MHz or 26.065-27.405 MHz, depending on the model. Modern Chinese export radios cover 25.615-30.105 MHz to include all of the 10 meter band and frequencies above it.


  • 25.615-26.055 MHz – Band A – often used by taxi cabs and trucking companies (AM mode in the Americas, AM or FM elsewhere)

  • 25.835 MHz AM – CB channel 19 “down three bands” – truckers are often heard here

  • 27.415-27.855 MHz – Band E – “high band” or “uppers”, mixture of SSB, AM and FM (FM rarely used in North or South America)

  • 27.410 MHz LSB – Often used for SSB in the USA, can suffer from interference or QRM from AM stations on 27.405 MHz (CB channel 40)

Hi Paul,

Thanks for contributing to the forum. List of Useful Side band Frequencies 1f44d 


This list and many others like it abound the internet and I'm sure with very good intention. A typical example is here :-

https://www.hfunderground.com/wiki/index.php/11_meter


Unfortunately the band is very fluid depending on current usage and often such lists don't age well or are updated often. The exception is channelised allocation by government organisations but even these change from time to time. (Such as legal use in the UK of frequencies and modes such as AM/SSB used in Europe, historically know as the Mid-Block of USA fame or even pre-legal UK days.)

Nowadays CB or 11m radios are much more frequency agile and always best to utilise such features especially when operating DX.

For example 27.555MHz USB, known as various names such as the 'Triple-5', 'Triple Nickel' or just plain 'Triple', is renowned as being the international calling frequency for DX. When conditions are ripe that frequency can be a cacophony of noise with hundreds of operators around the world all competing with each other and transmitting at once!! DX there can be difficult and some enjoy that challenge but there are better alternatives. One is to call out or transmit on a frequency away from but around the 555 where the frequency will be much clearer and you're more likely to be heard then contact established. In fact if you call out on pretty much most of the frequencies for long enough someone is bound to stumble across your transmission and answer your call. Wink

Channel and frequency allocation can be a bad thing with people believing they can place 'ownership' on such frequencies. We've often heard the complaints of not talking on the '19', keeping the triple 'clear' and even on frequency fluid Ham bands closely 'guarded' frequencies because that's where they run their 'Net' usually. I've often heard nets start up on Ham bands stomping all over stations already there and excuses of not hearing them yet complaints of our European cousins protesting being described as "Johnny foreigner".....so obviously did and can hear them!?!

Propagation conditions change all the time, from moment to moment and often despite computational predictions sometimes unexpectedly. 

So it may well be useful to listen out on certain frequencies for a 'lift' or activity and maybe work it early before it gets busy, but also remembering that's a big electromagnetic sky so worth looking around too.

Also very worth while taking a shout out on a frequency for a bit from time to time just in case a 'lift' is there and everyone's too busy listening so never know there's an opening.


If the next time you hear someone chatting on the 19, the triple five or whatever 'allocated' frequency just take a listen first before protesting.....maybe it's a couple of operators a hundred miles or more away from you on a short hop skip and surely then it counts as DX? It doesn't all have to be foreign sounding voices or American twangs.


Cheers again Paul and I look forward to further contributions to the forum.

All the best,
Victor
