My favorite way to dial in the horizontal frequency is to take a NTSC video source (usually a cable box or DVD player) , feed it into a scope and use the distance between H sync peaks to calibrate the distance between osc peaks in the osc. It's fairly easy to do, and all you need besides TV and signal source is a decent scope.
