Hello every one,<br /><br />Due to my ignorance, I stuffed up the low and high frequencies for the LNB <img border="0" title="" alt="[Embarrassed]" src="images/icons/default/blush.gif" /> <br /><br />What I tried doing is apply Phill's tip in the other post about changing the transponder frequencies in the OLD TARBS box (MDS 3100).<br /><br />It was my first time that I actually went into the "Installation" menu. The first thing I went into was the "LNB Settings" menu. I saw two entries there; Low and High frequencies. I thought these were the ones I had to change to 12674 H and S/R 22500. As I said, I knew nothing about these so I changed the low freq to 12674 and the high freq to 22500 and hit Exit to save. It did save (Doh!) There's no Reset button at the back of my decoder box and I tried unplugging the power, but the numbers I punched in were still there <img border="0" title="" alt="[Frown]" src="images/icons/default/frown.gif" /> <br /><br />Now, could anyone PLEASE tell me what the LNB frequencies on their ORIGINAL TARBS dish (and decoder box!)<br /><br />I appreciate your help.
