when icom demos their dstar digital audio, they suggest that the
digital will work 'deeper' into the noise than the "analog". my
concern when a fireman or cop is at the fringe,,, which will get thru
the message ??? who cares if it is scratchy if it gets thru... kinda
like us . did we make the contact , get the info or not.
Already there is some flak i read about background noise at a fire
scene can confuse and disrupt CURRENT digital audio on public service radios.
Would be cool for Digital Lyle ( eric&wayne) to have a digital audio
mode available for the k3.... esp if we can change out the algorithm
as they improve...
