Re: Modulation and Digital Cable with Comcast

It should.  According to CP's website, it will pass channel 116 which is 745
Mhz, and not channel 117 which is 751 Mhz.  Also according to CP's website,
it allows for injection of modulation at channel 121 to 125.  121 is at
775Mhz, so the hysterisis of the band cutoff is apx 25 Mhz which means
unpredictable results in that area.  As long as your modulator can inject at
channel 121 you should be good.  As a test, what happens now if you inject
at channel 121?  Do you lose digital channels above your HBO channels?  Can
you see a noisy version of your modulated channel?  I'm not familiar with
the DCT2000, but you need to make sure that it will tune in that channel as
an analog feed, and not expect there to be a digital channel to decode in
that range.
