Coverage is improved. Also, on the fringe areas, you either have
full coverage, or none at all - not the sometimes scrambled guff we
can hear now and then. Also, the radio itself can tell you if you're
in coverage or not.<br>

<div>Can anyone confirm that current digital scanners are still
not able to follow tait P25 trunked? From memory it was to do
with the data rate of the control channel (could be wrong). I
could get unencrypted voice with my uniden digital but was never
able to follow the conversation. Thats why I started looking at
software radio etc.

<div>It is ironic that the P25 system came into being because of
a need for radio systems and services to inter-communicate,
and now it is what separates them. Some will argue that P25
radios can communicate with the old analog systems (mixed
mode), but I've been told this is not possible with a trunked
system. (again, could be wrong)</div>

Hi Grunter,<br>
<br>
I think you might be on to something. I'm pretty sure the
media would have let us know if Ambo's were trialling or
had gone secure digital.<br>

Hello,<br>
I am still listening to ambos on the same
frequencies in the ESB band they have been on for
ages. This is on an analogue scanner and my digital
scanner with no "P25" coming up to suggest the
transmissions are digital and obviously if I can
hear them on an analogue scanner they aren't. Am I
missing something here? Are they being simulcast on
analogue and new digital frequencies for now or is
their going digital just a vicious rumour?<br>
Cheers guys.<br>
Grunter1.<br>
