26.765 MHz AM 26765 kHz Mexican Taxi Cab Dispatch Land Mobile Comms 04/15/2024
« on: April 15, 2024, 1741 UTC »
Starting hearing the dispatch lady - I believe out of Central Mexico or Northern Mexico on 26765 kHz 26.765 MHz 26.7650 MHz AM around 1630 UTC today.

At 1700 UTC or so, signal levels still roughly the same.  Coming in nicely on some U.S. East Coast online SDR receivers at 1730 UTC and now - 1740 UTC. 

Tell-tale end of transmission tone burst (EOT) - aka the "Roger beep" basically an automatic identification system. 

Frequency 26.7650 MHz AM is CB Channel 21 down one band.  Band C, Channel 21 on the regular 25.615 MHz - 28.305 MHz 240 channel export radio band plan....or Channel B21E / B21E AM on the alphanumeric channel plan.

Some QRM from FM mode traffic around 1741 UTC / 1742 UTC...26.765 MHz FM coming in at the same time as 26.765 MHz AM. 

Also noting some European based paging signals on 26.695 MHz, 26.745 MHz...so there's still somewhat of an opening to Europe / the UK, which is likely where the FM CB signals on 26765 are coming from.
