From what I gather here from the true pros I am incorrect on the clear matrix option. It seems the newest check switch is already taking care of that. I apologize for my tirades! I know there are times that a pure clear matrix is desirable but
I guess I am forgetting just when that is.
BTW Bourbon is not one of my favorites. Myers Dark Rum on the other hand!
If you use a quality signal meter (like the professionals here do) and align the dish, then do inside and turn on the receiver, the receiver will go through a boot up sequence which includes a check switch. So, the old check switch is no longer valid.
However, if you're using the receiver to align the dish (none of the professionals here would do that), then there will be no new check switch until the dish is aligned. You interrupt the normal boot up sequence and go straight to the menu/dish alignment screen. It's a catch 22. It doesn't do any good to run a new check switch until the dish is aligned and you can't align the dish until the receiver looks for the satellites, using the old check switch.
If you leave the old check switch with just one sat on it while you try to align the dish using the receiver, then all it will look for is that one sat. It's hard to align a dish on three sats when it's only looking for one, if you're using the receiver to align the dish. That's why I suggested doing a check switch with no dish connected. After you do that, the receiver will look for all sats.
When I first started full time RV'ing, most RV'ers I observed used the receiver to align the dish. Back then, there was only one or two sats to align. You could align the dish by listening to the receiver through an open window. Pretty easy stuff. Nowadays, most RV'ers use automatic dishes, so this whole discussion is mostly moot. But, if the OP is doing it the old way using the receiver to align and listening through an open window for the tone, I can certainly relate to him..............and I stand by my original advice.
