All,

I have a unique situation that has presented itself and I'm only posting my problem here as I am not sure where else to address it.

I used to have a Bell 5900 pvr in my bedroom and all was good until I purchased a new 9241. When I installed the 9241, it seems that the remote frequency used by the the 9241 interferes with the X10 system that I use to control all of the lights in my bedroom. Its amazing to see, if I plug the IRD into the electrical outlet behind my television then I lose complete control over the lights in my bedroom. As soon as I unplug the IRD, I regain total control again. After paying an electrician for 2 hours to help me figure this out, the conclusion that he came up with is that the only way to avoid this situation is to run a new electrical line behind my wall unit so as to have the lights on a different circuit from the IRD. This theory was tested by running an extension cord to a different plug in another room and voila the problem was solved.

So now, the question that I would like to pose, is there a way to change the frequency on the IRD to avoid all of this? I know how to change the remote address for the IRD as well I am aware that you can alter the dip switch in the remote to either UHF A or B, but all of this doesn't seem to solve the problem. Running a new electrical line involves making a few holes in wall, wall unit, etc. I understand that the 9241 uses UHF pro and the 5900 uses UHF.

Any help or suggestions would be greatly appreciated.

Cheers,

Smitthers

How about using a line voltage RF filter for the IRD? Some surge suppressors, such as this one, provide good RF filtering.

That's a good suggestion. Presently I use an APC power strip to protect the 3 components in my wall unit.

Any other suggestions that I could consider trying out on the 9241?

Is there any chance it is just your 9241.? It would be interesting to see if you had the same issue with a different machine.

Interesting problem.
Do you know what the exact frequencies in use for both are?
if this is the system your referring to saw this wiki entry
Seems like X10 might be around 310 MHz for the remote itself, and 120 KHz for the signalling between X10 interfaces.
Couldn't find much about the dish remote, other than what u probably already know.
http://en.wikipedia.org/wiki/X10_(industry_standard)#Power_line_carrier_control_overview

Not clear though whether ur issue is related to the various X10 boxes ur using interconnecting via the AC Line? Or if it's a radio related problem between the two remotes? Like I can't imagine the satellite remote actually transmitting anything, unless your pressing a button, so what's there to cause interference? I'm inclined to suspect something in the DISH receiver's power supply (likely a switched mode power supply, emitting trash) is distorting the 120 KHz digital signals that ride the AC Power Line wiring which allow the X10 interfaces to communicate.

Have ya contacted the X10 system customer support to see if they could offer some advice? Maybe they've come across this before and have a simple solution? Something like an AC Line EMI Filter to plug the Dish receiver into to help isolate it? Do you know if the electrician tried using one?

edit: note on flipping to legacy remote:

. All secondary remotes for dual tuners may also be converted to remote #1 by flipping the plastic bottom of the remote. This also switches its transmission mode from UHF Pro to regular UHF and IR, similar to how a 5900 remote operates.

majortom, your use of the quote;

had me re-reading the OP and I now do not believe it CAN be the 9241 Remote causing the problem.

If the 9241 is connected to the same Hydro supply it malfunctions, if it uses a different source it works fine.

Now if this is the same 9241, with the same Remote, in the same Room, in the same location, how can it be the Remote that is causing the problem.?

It is the Hydro supply.

smitthers, I agree with majotrtom, you have nothing to loose by trying the UHF, or even the IR Remote. I doubt there will be any difference but hey, it is worth a try.
