Bob tuned my F150-4E duplexer last Nov. and it is working great !  He has the proper test
gear, an  HP Network Analyzer and knows the tricks.

Has any in the group had any experience with tuning Sinclair duplexers model Q-202C?  The problem we are having with them is tuning them for a 600 KC split,  146.775 and 146.175. We can get one side to tune up to 146.775 and the other only to 145.800. The specs for these duplexers show that they should go to a 500 KC split without any problems. The person tuning these has the experience and the lab equipment to the job.
Thanks for any help in advance
Mike
