<p>Just a small basic explanation (there's more to it than this, but
you'll get the idea) for everyone, talking into the mic is good
practice for if/when they do go to digital channels. The reason
for talking IN to the mic and not AT it (and what a lot of people
struggle with, with digital changeovers) is there are several
microphones on an RSM. The front and/or top of an RSM takes your
voice, the other at the back and/or top will monitor ambient noise
for the DSP to filter out the crap. If you're talking at the mic,
especially from a distance (IE holding the mic down by your lap
and talking - often see it on Police 10-7!) then the DSP struggles
to determine your voice over the other microphones background
noise, and when it filters it out it could filter out bits of your
voice too. Of interest, I went to a Motorola conference last year
where they released a new RSM for the (I believe) APX8000 series,
which had 5 microphones on the RSM.</p>
<p>This is nothing but poor radio habit, Digital isn't as forgiving
as Analogue. If you're holding a mic more than 4 or 5 inches away
from your mouth, slap yourself and do it properly :) Simple
things like that help with Digital changeovers, and helps the poor
buggers at the other end hear you over the background noise in
Analogue, and hear you in the first place in Digital.</p>
<p>I'd assume that there is probably a second zone in these radios
that have P25 (I still don't understand the benefit of P25
logistically vs Mototrbo but that's another conversation) channels
in them, which mean the new radios could take the benefits of
digital, but capable of flicking to the analogue channels when
mixing with say Rural Fire who may not have been rolled out the
new radios yet. I would expect the idea is to use these radios in
P25 mode as soon as possible, to take advantage of the APX
features. Analogue has little background noise reduction compared
to Digital, and can't use digital features like GPS, DCDM (one
simplex freq being used like two channels) which I assume P25
radios can do like MotoTRBO, etc <br>
</p>
<p>Also to the OP, Kiwirail VHF frequencies changed a few years ago
to a set nationwide, it's not a new change if that's what you
thought. They reuse repeaters, much like Ambulance (although
Ambulance is a little different in that they use different tones
for different areas)<br>

I have used the new radios during training, they're very nice.
The noise cancelling technology in the microphones is really
impressive, but for someone who's been using radio for years
it's counter-intuitive to start with (you need to talk directly
into the mic, as opposed to 'across' it... if you talk across
it, you won't be heard).<br>

didn't get the contract, however you can almost bet these
will be DMR channels and afaik there's only a couple of
scanners and certain HT's capable of receiving these
channels otherwise you are stuck with a PC for decoding.
