MX-600 Directv Sony A65 Sat. Receiver Head Scratcher Mike or Dave Help!

I have had mx MX-600 for a couple of month now and have used it on several Directv sat. receiver boxes without issue. I have a problem that I find odd that I am hoping someone can help with.


First I have the transmitter mounted behind my rack in the basement of my home and the MX-600 is used in the main level which is only about twenty feet away. I have the emitters fed through the back of my rack and mounted appropriately on the front of the sat. receiver. I replaced a Philip's Directv box (horrible receiver by the way) which a Sony A65 box and I deleted the old codes for the receiver and reprogrammed the MX-600 with the Sony sat code. Sony only has one so it should not be an issue. I tried it and got nothing!! I unplugged the MX-600 base station and brought it around the corner into the theater room were my rack was and if I keep the base station about five feet away with no emitter affixed to the Sony receiver box all is well and everything works fine. I have tried a different emitter and I still get nothing. Well I should not say nothing, once in a while it will take a stray command but for the most part nothing. What is going on? I have tried everything I know including fresh batteries for the remote. Again, it works fine if I keep the MX-600 base station in the same room about five feet from the box. I would rather not keep the MX-600 base station were it is now as in the same room, I liked it hidden in the back of rack with the emitter feed through the rack and affixed to the front of the receiver. I have tried cleaning the eye on the receiver and that did not help. I need help, what am I doing wrong? The MX-600 worked so well on two other Sat. receiver boxes, why cant I get it to work in the same manor this time.


Thanks in advance for the help!
