R/C channels:


26.995 MHz 26995 kHz - At 1705 UTC tuned back in, hearing two FSK signals (26.995 MHz USB, center frequencies 26.996 and 26.997 MHz...now hearing what sounds like ROS data mode mixing in (again on 26.995 USB).  Numerous data signals on or around 26.995 center freq, 26.990 MHz to 27.000 MHz or so)

27.045 MHz 27045 kHz - Weak AM voice heard, sounds like a taxi cab dispatcher

27.095 MHz 27095 kHz - modulated FSK signal right on 27095.0 kHz, along with data bursts (similar to the ones usually heard on either side of 27.255 MHz) noted.  Several AM voice signals also heard, Spanish language

27.145 MHz 27145 kHz - 27145.2 carrier noted at 1711 UTC...unmodulated carrier or CW signal...then nothing.  At 1712 UTC, a multi-carrier FSK signal appeared on frequency, dial frequency 27.144 MHz USB or 27.143 MHz USB

27.195 MHz 27195 kHz - Noting a mixture of AM voice, the usually heard FSK data signal bursts and weak FM voice (Spanish language) on 27.195 MHz (R/C channel 19A).  Later SSB voice signals (27.195 MHz USB - Spanish language) also coming in with the mix!  Most of the signals heard here are regular AM voice signals mixing in with FSK data bursts

27.255 MHz 27255 kHz - Several FSK data bursts noted (usually with signals on 27.252 MHz or 27.253 MHz on the lower side of center frequency and again on 27.256 MHz or 27.257 MHz on the upper side of center frequency).  27.252 and 27.256 both very strong, another (different bandwidth) FSK burst noted on 27.254 MHz (possibly off-frequency).  LSB voice noted as well 27.255 MHz LSB mixing with AM voice and the data bursts.  Checked 27.255 MHz again at approx 1930 UTC and the usual data bursts are still there, but a bit weaker than before.  As expected, AM voice signals are also present on frequency (after all, 27255 is legal CB channel 23.
