Re: Modulated Channel Interference

I don't think I've tried either of those.  I'm going to scrap it.  The
bought all the pieces suggested in the manual, ie combiner, filter and never
really satisfied.  Everything goes to crap the minute I combine the signal
with the cable.  I paid $6 for the splitter and $34 for the filter.  Thanks
for all your help but I going to send the stuff back.  I'm sure it isn't the
equipment but I'm tired of buying stuff.  The 1ch modulator I bought at
radio shack to test to see if it was the modulator, when I brought it back
the guy said "we never have a problem with these?"  I think I'm well capable
of installing correctly but I think there is something causing my problem.
Oh well.  Thanks.
