I just got an HR24-500 and I'd prefer to use it in RF mode. I notice when in this mode that half of the commands I send go double, and I'm not pressing the button twice. For example if I want channel 2 I'll briefly hit "2" and "22" is the result. This happens pretty randomly but very consistently with all keys. It's driving me nuts. I did some searches and other people have reported this as well, any fixes? I have an old HR20-100 in my bedroom that I made an RF antenna out of some stripped coax for and it works in RF mode flawlessly, if I can't get this working right I'll have to switch these 2 as the living room gets heavier use. thanks in advance!!
