I would like to solve the following problem.
I have an inexpensive VHS VCR and a two wire
cable system that has a mechanical switch to
switch between the two cables.  This limits
the stations from which I can make unattended
recordings.  I would like to build a programmable
"cable switcher" that would switch between the
two cables at set times.  Does anyone know about such
things that are already on the market before
I take on such a project?  If not, can anyone
provide me with ANY information (circuitry?)that
could help me in building the cable switching part?
The programmable clock is no problem for me, but I
don't know much about 75 ohm cable, splitters,
etc.

I guess I could go out and buy a Mitsubishi 430 that
has the A/B cable switching but I really don't want
to.

Thanks,
