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

If the company you are refering to is D&D Electronics, I would advise you to
call the number yourself.  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.
