Well TAXIS are FM these days and you wont hear them, you might get a bit

Old bill is fast going off to Airwave TETRA and you will not hear him at
all!...

You may do,,, ;- The TETRA mobiles are pulsed, so may produce AM
envelope demod of the data pulses if they find enough nonlinearity in a
suitable place. However unless you are worried about a police raid, the
powers reaching your audio gear should be well below what you get when
someone uses a mobile phone in the room.

If U reckon U can decode the TETRA old bills using Jim, then there would
be a lot of people very interested in that!....
