Analog any day. That digital audio sounds very compressed and unnatural. You would never be able to recognise know who it was that was transmitting.

Digital radio... look forward to a low-fi future.

Wow, all that money for a portable with noise cancelling technology!!

Think of all the money you could save by buying a standard analogue radio and using a noise cancelling mic.. They have been doing this for years in aircraft and rotary wing aircraft.. It's not rocket science. This is just a slick marketing ploy by Motorola, to flog overpriced hardware to gullible consumers..

I don't know about you, but the highly compressed audio of the digital test sounded awful - Typical P25 crap!

you can keep them mr king you suck

sorry, places 2times because I thought textspace left was too short

I don't know which speech-bandwidth is used but don't forget that already 100 years ago in the vaccuum-tube era... uncompressed analog voice had a voice-bandwidth in the range of 3500Hz through a phone-line. There is no development in analog technology anymore but I can still transceive analog with far superior soundquality in the same RF-bandwidth compared to digital. compressionless and 80dB SNR is easy

@Polybun no sir I am sorry. Its easy to blow through earmuffs. It is easy to produce 140dB SPL at 0.5cm from a 40mm speaker. So what is the problem ? @dv6000hp : to say something positive; the good thing of this digital system is that it is spectrum-efficient. That is where the focus is, and on the 2nd place -so it seems- is the sound quality.

[Polybun]

@djyuroon yeah, try fitting that under a hard hat. for that matter, try finding one loud enough to get through ear plugs and ear muffs.  You boys have just no idea how loud things can get on a big fuckin' planer mill.

grandfathers wellcome to digital era, say goodbye to your vaccum tube radios or analog radios, yes digital sounds like ROBOT but is the digital era begining. In the past the AM sound has the "Hi Fi" now is DIGITAL!!!

you could talk to nascar drivers XD

[dv6000hp]

Another thing, Just because a kenwood or mototrbo use AMBE vocoder, By DVSI, Does not mean they will talk to each other, its in the air interface were it happens. Efjohnson uses AMBE+2 and is backward compatibele with IMBE that motorola uses in there xts line.Again it in the air interface that matters, as far as compatability it is not necassarily the vocoder.

Y do people hate digital so much when they probably have never used a digital radio in there life.
