11 meters 28 OCT 2021
« on: October 28, 2021, 1236 UTC »
First off, happy FM is now legal on CB radio day!

At 1230 UTC the band is pretty quiet.  However, there is some faint traffic on 26745 AM 26.745 MHz AM - it sounds like a taxi dispatcher - female taxi controller reading numbers in Spanish.  26.745 MHz is one of those frequencies that often stays clear because its so close to the "big radio channels" - in this case, 26.705 MHz, 26.715 MHz and 26.725 MHz.  26.735 MHz is channel 19 down one band so its often used by truckers and other business or land mobile users looking for a clear channel.  See also - channel 19 up one band - 27.635 MHz, channel 19 down two bands - 26.285 MHz and channel 19 down three bands - 25.835 MHz.  I've heard local traffic on 25.835 MHz AM numerous times, and it was always truckers.  On most export radios, the legal CB band is Band D, so 25.835 MHz is channel 19 on Band A.  Its often easier to simply flip the band switch and leave the channel selector knob alone.  Need a clear channel?  Well, you're both already on CB channel 19 27.185 MHz..simply flip the band switch from D to A and you have a clear frequency. 

Also noting some activity on channel 7 - 27.035 MHz AM - appears to be Latin American stations

1400 UTC - the band appears to have quieted down a little bit...checking numerous KiwiSDRs on the US East Coast and it appears like things are pretty quiet

The band might be opening up...just a little later than it has been in the past week (weeks?).

CB Channel 5 is active, same with channel 6.  Noting some AM signals on 26.585 MHz AM, as well as the 26.715 MHz AM big radios channel.  Some weak AM voice on 26.765 MHz appears to be a taxi cab dispatcher...time to check the other common taxi frequencies and see if maybe those are active too...
