Working great now. Thanks Lads! Celwave notch duplexer (tuned correctly) was the last piece of the puzzle.... I hit my repeater from 5 miles yesterday on a walkie - inside a bus.... Going to do some more upgrades. I purchased a used 19" 6u rack enclosure from ebay. Going to build and isolation box for the receiver. Replace jumpers with dx engineering 400 coax double shielded and silver plated brass connectors. Added a Sec 1235 30amp switching power supply to help run some fans... I also added a station Id from an old surcom siplex repeater circuit connected to the RICK. Thanks for all your help, everyone! I learned a lot and had fun! 301
