27.255 MHz AM Taxi Cab Dispatch + RCRS Data Bursts 2250 UTC 10 Sept 2026
« on: September 10, 2026, 2253 UTC »
Received locally here in Richmond, VA.  Also hearing it on the N1NTE SDR receiver.  Lots and lots of QRM from AM voice, FM voice and data bursts (RCRS - Class C CB radio).  Most voice traffic is in AM mode 27255kHz AM.  CB radio channel 23 AM.  Heard Portuguese language and English mixing together on top of and with the taxi dispatcher lady - Spanish language taxi cab on CB channel 23.  MFSK data BURRRTTTT BURRRRTTTT BUURRTTTT bursts every...0.5 to 1 second or so...sometimes every 5-10 seconds.  Seems to be multiple datalink networks on the same frequency coming in. 

27.255 MHz FM data FSK bursts - 25 watt power legal per FCC rules
