Hearing activity below channel 1 down to 25615.  Noted some AM activity on 27.545 MHz at 1614 UTC.  Also sporadic SSB signals in the 27.4 MHz to 27.7 MHz region.

Lots of AM voice activity on 26.585 MHz, 26.765 MHz, 26.565 MHz, 26.205 MHz, 26.935 MHz, 26.945 MHz, 26.885 MHz, 26.865 MHz and of course the taxi dispatcher is active on 25.695 MHz AM / 25695 AM taxi dispatcher YL and OM taxi cab company on 25.695 MHz.  One of many Latin American taxi companies and/or land mobile users on the 25 MHz band (starting at 25.615 MHz and working your way up to 26.955 MHz...). 

Lots and lots of ISM hooks on the waterfall (W3HFU KiwiSDR) as well.
