I have my dish nailed on both 110 and 119 it has never gone out in a rain,snow,etc. When i hooked up my fta receiver i can get about 67 radio channels . But when im watching tv or radio on one transponder i get bored and check whats on the channel 20 channels above it. It is no olnger getting a signal. So i go to the settings and i see the transponder is no longer locked. Well persay that the freqency is 12201, i have to eneter 12200 then 12202 and then i have to enter the orginal frequency to lock it back. Then i exit the menu and watch tv for about 20 minutes, then i see whats on the ohter channle (its a diffrent transponder), and it went back out again. Long story short i have to keep having to renter transponder info, it;s like the receiver keeps changing it 1 mzh or something. I save the data, so it's not getting lost when i exit, what should i do?
