I have done a lot of reading , but , failed to find an answer for this problem . When looking for a sat. signal , on a verified active transponder , using the motor , I don't find a signal as to where it is . If I get it to where I know the sat is , I don't get a signal unless i go either up or down a transponder , then , back to the right one , a signal appears . As soon as I move the motor [ either direction ] the signal disappears again until I repeat the above. Scanning is fine etc. Channels are fine . I love this little thing , but this is a puzzle to me.
