So would a "digital Scanner" be able to pick up the digital radio (DAB)
which is broadcast on or around 225MHz and be intelligible to listen to ?.
I'm assuming normal DAB is not encrypted ?

Cheers

Surely, even though the scanners you mention can receive digital
signals,
broadcasters such as the police would still be unintelligible ??. I hope
so,
after the amount of money the local police force have spent on encrypted
airwave radios !!

PS Are the 'digital' frequencies you mention still within the 0-1300MHz
band
scope ??

Andy, don't confuse "digital" with "encryption". The two are separate
functions. A signal can be analog * or digital, plain or encrypted, or any
combination of the two.

The digital scanners can receive a digital mode called APCO25. If your
Police are using this mode, unencrypted, then you will be able to hear
them.
If the Police are encrypted, then as a previous writer said, you won't be
able to decrypt it within any reasonable timeframe.

Our Police use digital at the 468MHz range, our State Government is
planning
on changing it's 400-420MHz system to digital in a couple of years, your
local Police may be in the 800MHz band. You'll need to do some searching
for
that information, it varies.

* analog = analogue (Barry O'Grady, author of Dictionary for Pedants)

Nope. That's a whole different digital mode again, and different to the
sound on digital tv and different to the digital pay tv. Sorry.

Brad.

Cheers Brad for the useful info !. Yeah, it's getting a very complicated
scene out there. When i started scanning (Aircraft mainly) about 20 years
ago, there was just AM/NFM/WFM and SSB (USB/LSB/CW). I was scanning on a
Signal R532 ! (beauty !). No digital, airwave, tetra, motorolla, DAB blah
blah !!!!!!!!!!!!

When I started listening (scanning? what was that?) there was no USB,
LSB, TV ...

Just plain old AM and FM.
