Thanks for the quick reply The revers pair is a good point.
I am in a remote area and did the full coordination but still we have had some odd ducting here as I am close to 9K mountains and I am at around 4K feet to start with. Tony I have not ran it without the tx pl. I have a few folks that like that including myself as I drop the tone before the TX, the controller is a ICS. But still for testing I may do that. I have echolink so I hook it up at night to the Ireland conference and set the system to listen only so I do not interfere with folks. Then with a program called echoproducer I can log each time the system gets kerchunched. sometimes its fine other times the log is big. Sorry I failed to put down its on 147.000 TX 147.600 RX. I have a repeater info page off of my weather station site. http://www.josephoregonweather.com/repeater.html --- In Repeater-Builder@yahoogroups.com, Tony KT9AC <kt...@...> wrote: > > Scott, > You are not alone in this!!
