I have a customer with a Dish Network model 4000 receiver. He currently has a remote that is UHF. Does anyone know if this unit can be controlled by IR?
I ordered a remote from Skyvision which was suppose to be IR but found out that the IR is only for the VCR, TV portion but the satellite receiver is still UHF not IR. I have also been told now that all Dish Network receivers are UHF with the possible exception of model 301. Can anyone confirm the above? If it is true that the receivers are all UHF - how can I controll it with a Marantz 5200 remote. Any help and or info would be appreciate.

Yes and no. The 4000 may be one that needs to be modified to use IR, some of the old ones are like that. Search at dbsforums.com for details. I believe this defeats the RF, though. You'd have to decide which you want.

Later models higher than the 3 series are combo units that do both RF and IR with no modifications.

I think all the new dish recievers are UHF/IR being able to be controlled by both. Some of the older ones have to be forced into IR by removing the antenna and switching a setting. The 4000 cannot even do that I don't believe. Requires hardware change that you have to do yourself. I have a 501 which I control with the dish remote and a NEO. A new download to them gave them discrete codes.

Many of the current Dish (and Expressvu) units are IR. That has been the case for some time - but the 4000 was an exception - UHF only. There are plans on the web to make the conversion, but prolly not worth it given the cost of used IR receivers. The UHF remote control also puts out IR.
