Follows settings found optimum for my Kantronix KPC 3+ when using AIRMAIL on local VHF channels. Critial settings may be changed by other scripts and are listed in Red.  Watch these closely for undesired modification.

When I go back to AIRMAIL from programs such as RMS packet, I check this list to be sure parameters are correct.  They will often be corrupted.  Its poor software design to modify something than not return it to the state you found it upon exit, but thats the price you pay for "free" SW so you must forgive others mistakes
