Other then that I couldn't tell you why, but I know it doesn't.

301 should have an ir remote unless you had some sort of UHF converter kit. If it is really uhf, the reason is that the 211 only recognizes ir signals, not uhf

Thanks, well dish sent me UHF PRO KIT 10.1 remote for free as i had the previeous receiver that i could control all over the place,and the 211 remote couldn,t, so i'm set with one remote only for the room where i have the receiver and the 10.1 UHF pro KIT i can take it to evry where includind the cealler where there's a tv, that's cool.
