26.765 MHz AM Mexican Taxi Cab Dispatch CDMX 2005 UTC 7 March 2025
« on: March 07, 2025, 2012 UTC »
Nice signals this afternoon here on the U.S. East Coast.  Received using portable radios, nothing fancy.

Checked some East Coast SDRs, "Juanita" is coming in very nicely via the W3HFU SDRs, with some minor QSB / fading at points.   Her transmitter is slightly off-frequency, carrier on 26764.55 kHz at 2008 UTC.  Decent AM modulation, very distinctive end of transmission tone "Roger Beep", seems to be (roughly) 1900 Hz or so frequency (the end of transmission tone). 

Noting taxi cab radio transmissions (drivers replying to the dispatcher) at 2011 UTC.   

Mobiles' carrier frequencies:

26765.1 kHz
26764.7 kHz
26764.8 kHz
26765.2 kHz

at least so far, I'm sure there are additional mobiles on frequency that I just can't hear..
