I've been modulating channels on my home system for years. I've been using a Channel Plus 3445 (4 channel modulator) and a filter that filters out 75-80. Problem is that with 2 channel separation I can't input all 4 channels off of my CP3445. This hasen't been a problem until just recently when I added the 4th device. I used to modulate on channels 75-77 and 79. Put something on 81 and it's all fuzzy.
So I bought a Channel Vision LPF-600 which is supposed to block 86 and above. The part I missed was at the bottom of the description it says it won't block 95-99 on cable systems. Seems misleading when it says at the top of the description that it blocks >86.
Another problem is that 88 & 90 when assigned to the modulator are fuzzy. I don't get a clear picture untill 92, but by the time I go to
92 then I run into the upper end (95-99) which it also doesn't block. Defeats the whole purpose of why I bought it. I put it in series with my other filter, kept 3 of my channels at 75, 77 & 79 and put the 4th channel at 92 and everything is clear. Only problem is that my cable company uses channel 79 for a channel I really want and have been missing for years.Why isn't the LPF-600 block above 86 like it's supposed to??? Picture isn't clear until you get to 92, then there is not enough open channels before I run into unfiltered territory again. Aggrivating!!!
