I have noticed that the Openbox isn't the best receiver to judge signal quality on. I don't think I've ever seen a transponder light up the meter on the Openbox higher than 76-77q. Normal is 70-75q on most channels across the arc. It shows weaker, but rarely stronger than 75q for me.
why would you send a e-mail to the channel when its obviously a transponder issue (since all the channels are at low signal) and not a specific channel issue?
