[Xastir] Strange ACK behavior with a Yaesu VX-8DR and Xastir 1.9.9 CVS

[David A. Ranch]

Hello Everyone,

My first post here on the list.

I'm looking for information Xastir v1.9.9 (last July CVS release)'s 
"Satellite ACK mode" feature.  Specifically, I was playing around with a 
buddy (n1nec-7) who is on a Yaesu VX-8DR and I was in Xastir (running on 
Centos5.5) in KISS mode on a Kenwood D710.  If I would initiate an APRS 
message, his HT would almost instantly send an ack.   I was in Santa 
Clara, CA and he's was Fremont, CA (<20 miles away) and I couldn't  
directly hear his local ACK.  I would receive the digipeated ack.   
Unfortunately, Xastir would NOT recognize the ack and thus Xastir would 
re-transmit the original message to him again.  Now, once I enable 
"Satellite ACK mode", Xastir would accept his ACK and stop transmitting 
the original message.

BUT...

Now, when I enable that "Satellite Ack Mode" and N1NEC would now 
initiate an APRS message to me, I'd never ACK his message!  Grrrr...


Look at some of these logs with all the DUP messages, etc:

This sure seems like a bug to me.  Thoughts?
