i have the KG-1000's set up for a repeater and pretty happy with their performance, I'm making contacts with mobile's 60 miles out.. I'm, setting on a hillside about 500' overlooking the Indian Wells Valley using a Tram 1182 on 30' mast. I also cleaned up my mobile Duplexer with my Nano, the factory tune wasn't very good. i am concerned about the duty cycle on these KG-1000G radios, they get very hot after about 15 mins of continuous use. I plan to use these as mobile's so I actually have two Maxon 8402A radios on order, they create a repeater much like the KG-1000 but better because they are commercial radios and have a 100% duty cycle. They are also a little cheaper then the KG-1000 radios. If you decide to go with the Maxon's be prepared to wait about 60 days, they are on back order. I'm also using EchoStaton with a RIGblasger for my ID Controller. IMO, this is the best way to go for creating an I'D controller on your repeater. I have mine set up for Voice I.D. with a time and temp stamp. EchoStation has a lot of flexibility and the software is very cheap, only $19 bucks. RIGblaster ties it into the radios via the Mic ports. Very easy to set up.
