I had problems with sinc initially but the following modifications solved some of the problems: - replace both of the variable caps with Radio Shack #272-1340 the increase range (6-50pf) should help - use an offboard regulated switching power supply for all the voltages--remember those TI power supplies RS sold for $4.95? - use a clean video source--some of the newer VCR's do terrible things to the video output, as well as muting the audio - shield the board - use shielded cabling for the video input/output > >The technical support number given by the company that sold the kit is >518-854-9280.

It would be worth the toll. The person on the other end is an independent techie who has a lot of experience, having built 100's of kits, and even has made mods/adds to the circuit to make it lock all the time automatically. Call for more details. ---------------------------------------------------------------------------- Dzung T.
