WRUE538 Posted October 8, 2022 Report Share Posted October 8, 2022 You'll hear differing views on repeaters. "Made for HD use" used Motorola's, don't waste money on a cheap setup, etc. Initially, I hoped I could use 2 KT-8900's for light duty with a homemade jumper. Naysayers were correct. They work crossband decently, not well in band. I'm at 6800' with optimal conditions. Mostly reaching areas 500' lower. I only needed 28' of LMR400 to the antenna, $100 Harvest 5/8 wave. $125 50w duplexer. The key, I believe besides short high quality coax was fine tuning the duplexer with a nanoVNA. You not only want the lowest notch possible, but also ensure you aren't pulling the passing frequencies down. Bottom line, I have VERY clean transmission using a stock Baofeng GM-15pro in a car 20+ miles out. Which is only 4.7w. I haven't really tested further distance yet. Obviously my Nagoya 771G antenna would do even better, or a mobile unit far better. It's a shame to use the KG-1000G's only as a repeater, as they are nice radios. But they are amazing for my use. They stay very cool in continuous use. The generic China 50w repeater is great, once dialed in. The threads are a little touchy but attention to detail makes all the difference. I'm probably most impressed with the Baofeng GMRS radios. Same as the GM30 radioddty but I like these better. Was sure others would want to know about a setup that actually worked well. According to propagation software I ran and plugged in the values, a good mobile should get me out around 75 miles in good line of sight areas. We'll see as we experiment. But thus far, this setup has worked excellent for me. Quote Link to comment Share on other sites More sharing options...
