On the 2000Z AO-27 pass i was on this pass and i hear 2 folks discussing about 
a hamfest and they seems to be on a trunking system as we can copy clearly the 
"trunking tone" at the beginning of their transmission. AO-27 was over the  
eastern side of NA. If someone is aware of an amateur trunking like repeater 
this can give a clue even if the path of AO-27 was covering near all North 

P.S. with 50W on a 14 elem cross yagi their signal capture mine!!! at a time!!!
