Moca kills Comcast DTA box

[jerryk]

HI,

We just were forced to get a Comcast DTA box to get any channels on one of our TVs. As soon as I got the box I noticed that the picture seemed a little off. More testing reveals that about a third of the channels (ex 2 works, 3 does not, 10 and 11 do not, but 12 does) do not work. If I power off the MOCA box (Netgear) the interference disappears and I can see all of the TV channels.

Any thoughts on how to troubleshoot this issue?

FWIW, I have a TV downstairs where the other end of the MOCA box is located and the Tivo box with cable cards has no issues receiving channels.

Thanks,

Jerry

not sure what a DTA box is.. set top cable box with DVR?

Whole-house DVR uses MoCA too - in my cable system.

Your own MoCA should a have a utility allowing you to change frequencies. I'd try that. If this doesn't help, I'd try inserting an F connector pad/attenuator, like 6dB or so, at each MoCA box.

Thanks for the info. I will see if I can find the utility. I this something on a disk? I did not see any switches on the units, Netgear MCA 1001. I think it is V1.

FWIW, A DTA is a cheap ($2/mo) box for basic digital service.

DTA.. I thought (in the US), those had to be free.

I thought so too, but a little reading said not for cable.

On the attenuator, I assume the thought is reduce the signal strength coming out of the MOCA box so it does not interfere as much with the TV signal? Anyway I will get a couple. It looks like they are pretty cheap at radio shack.
