I've got a Uniden 251 UHF repeater that I've crystalled and tuned to our UHF freqs, but I have no way of tuning the duplexer. It's a 6 cavity Celwave 526-R-SR. I have no paperwork on it and could really use some help. Anybody got any ideas? If you do call me at 606-365-0130 or if you want you can catch me on 146.460 simplex in Lincoln County. Thanks Ron AG4TY
