Update:  at 1650 UTC, 26.805 MHz FM is still active.  I also noted a mixture of AM, FM and LSB signals on CB Channel 40 frequency 27.405 MHz.

There is also an unmodulated carrier wave signal on 27.145 MHz, plus two different data signals, one centered on 27.144 MHz, the other centered closer to 27143.5 kHz 27.1435 kHz.  Their bandwidths are within the RCRS regulations either way.
