OK, for someone new to this...

What is a practical way that this can be implemented? The unit i will 
have at our FD site is a KPC-3 (v6.0 that supports APRS functions) 
driving a Kenwood TM-251. I was looking at Bob document...


and wondering if this kind of format could be used for the FD 
object...or is there another way? I see some say to put the FD-<call> in 
the MYCALL field...and then put talk-in, other info in the BTEXT field? 
OR how?

Any help appreciated.
