[Wa4prr]

Eric, thanks for the info.  I will see how it goes with my existing (older) 2 Meter radios in a mixed digital / analog environment.  73,

In mixed mode, however, the repeater won't transmit the PL tone during a digital transmission so if you are running tone decode you shouldn't hear the data (only see the busy light).

>> Bob, thanks for the info.  The details of the modulation scheme reminds me of reading NASA specs!  At the current prices of the FM / Digital HT and mobile radios, most of our retired guys may not be able to afford new radios.  I know I can't right now.  (Reminds me of AM vs. SSB in the really early days on VHF!)
