I am a retired engineer who frigs around with his system. This has always got me confused and miffed :- Say you have 119 and 110 and the switch check shows both OK. You go to look at the signal on various transponders on 110 and 119 to frig with the dish. You start, say selecting 119 to look at. That works OK but when you switch to look at 110 it continues to display 119 signal for that tspdr but with the message wrong satellite, like selecting 110 didn't change what it's looking for to identify, and display. Likewise if you start off with 110. Can this be made to work as expected? The only way I have now is to disconnect the feed I don't want to look at. My setup is a 512 with a sw21x switch from two legacy lnbs in a legacy offset dish. I have also tried the vanilla sw21.
