Digital Versus Analog Radio Testing
But what you don't hear or see... is the Latency built into all the radios using the digital mode. In fact the video has been cleverly modified/edited so the digital voice audio on the receive side is in real time sync with the video picture. Put two correctional or street police officers in an emergency situation where two more more radios (in digital mode) are in ear shot of each other and all he11 can break loose when the latency gets in the way of and and all rapid communications. Better than 98% of the digital radios I know are in Public Service run in the analog mode 100% of the time. Analog will be here for a while... at least in Public Safety. cheers, s. > "ka9qjg1" <ka9...@...> wrote: > > As Scanner Listeners And some on this group are actual users ,I found this > very informative.
