We do plan on tagging off the same source for the h and v sync lines, at least initially - we may look into doing this a different way later on if all goes well.
Are you suggesting simply inputting the amplified signal into the second monitor's video input, or still using a VCR or something to demodulate the signal?
After the wideband amplifier, should we be using some kind of filter to eliminate noise from frequencies other than the range we are aiming to capture and display? If so, where would we be able to get ahold of a filter like that, or are there plans to make one somewhere?
I found three preamps from ramsey electronics that looked like they would achieve what I was after, the PR2 broadband preamp (

http://www.ramseyelectronics.com/cgi...action&key=SA7), and the PR100 high performance 2 meter preamp kit, which doubles as a signal filter (
http://www.ramseyelectronics.com/cgi...tion&key=PR100).
Based on the information about each it seems like either the PR2 or the PR100 would be what I'm after, depending on if I want the filtering incorporated or not.
Could it be simpler to initially attempt van eck phreaking on televisions instead of computer monitors since h and v sync rates are standard on TV's?
As far as using a VCR for RF demodulation - how would I go about controlling the AFC, is it something I could wire a potentiometer to in order to tune or what?
Thanks for all the assistance, Jeff
