The switch for channel 3 and 4 is the modulator output channel, set
one to channel 3 and the other to 4. You can use a mixer (a passive

each.

Thank you for replying. I had to read this a couple times to
understand and that's part of the reaosn from my delay in writing.

Now, which is better? Should I just say thank you or say that I had
done this before and it didn't work. I think the signal was too weak
from one or both sources after having gone through the mixer/splitter
reversed.

If you are planning to get a third box you will have to look for

Yes, a second box, but only for another tv, so still only two signals
at most at any one tv.

a modulator that outputs to VHF III or UHF.
Keep in mind that placing these devices to standby will usually turn
off their modulador leaving free channels for other modulators and
will reduce wasted power.

Okay. That is helpful. Thanks again.
