[App_rpt-users] App_rpt-users Digest, Vol 91, Issue 29

[Jeff Carrier]

Thanks for the trip down memory lane Steve.  Quite a few things I wasn't
aware of.

If I hadn't said so lately, a Tremendous thanks to Jim Duuuude, Steve,
Steve and the team who made this project possible!  You guys provided a way
for me to link repeaters in a new way.  Sure there were other methods of
doing so over IP but app_rpt allowed us to do it on a private IP backbone
if we wanted to.  Now we have 2 large systems in the state using app_rpt as
the linking system...bye bye UHF analog links!  There is Allmon courtesy of
Tim which is another invaluable tool! Then there's voted receivers and the
list goes on and on!


Thanks guys!!!!
