IAFC Digital Audio Report Due this Summer

[scannerfreak]

Testing to determine how digital networks audio quality is affected in high-noise firefighting scenarios is complete, although a full report with the results will not be released until this summer. Although the actual data is not yet available, the findings confirm what firefighters have known for several months: Some current digital systems have problems in loud-noise environments.

Interesting mention of the testing process. They tested "baseline" (read: Motorola) Project 25 Vocoder against "enhanced" (read: EF Johnson) Project 25 Vocoder available in some (again... EF Johnson) radios.

Very interseting study, goes to point some interseting facts. So, the choice comes down to full Enahanced P25 or 25 mhz analog, I know which one I'll take.
