[aprssig] APRS-B?

[Thomas Krahn]

Bob,

Maybe he first thing is to standardize a "APRS-B" frequency in the 70cm 
band and a deviation that is compatible with the amateur radio 
regulations in most countries. I have send you a proposal several month 
ago for 432.900 MHz and I'd be interested what you and others think 
about that.
