Looking into this, it appears to be a language Kenwood radios understand.? ?My guess???? is that Yaesu radios will not?? I haven't checked if APRS.FI understands this syntax yet, but I shall.??
So much potential in APRS I have never heard of :(
Thing is, +900 doesn't shout +9MHz to me and I can't imagine casual APRS browsers (most who will be using aprs.fi let's face it) will either?? So I'm torn, rather.
