Im using my openbox s9 on my 12'er with a dmx241 lnbf and no switches for c band only. I have the lnb set at 5150 on the box and everytime i do a blind scan i get duplicate channels and transponders. for example, the rtv's on 3800V29124 will also scan in as 3800H29124, so i get 2 tp's and 2 channels. Anyone else run across this? Is'nt 5150 the right setting? Never had this happen on any other box before.
