To Dishstaller, I appreciate your compliment. That was an epic SNL skit !!
To RVvaquero, I appreciate your coments but everything you mention has been considered:
Firstly, I use OTA very rarely - mainly for sporting events.
Secondly, I'm well aware that, since certain channels may scan from one directon while others from another directions, and remembering the difference, for certain stations I will point the antenna in a suitable direction. Some stations come in for almost any direction. In my original list (which has now been discarded), I had about 18 OTA stations and all of them were scanned from the same antenna direction. Even so, the Dish receiver was very particular about ABC (local KOAT 007-01). In the new geographic setting, it gets KOAT easier. Several months ago, due to a contract dispute, CBS (formerly local KRQE on 013-01) was dropped; it hooked up with KOAT as KOATCB (007-04) which is the one station I really needed. But I had to rescan to get it ...
All of ths points to the flaw in Dish's OTA software that prevents scanned stations from simply being appended to a master saved list. The user should be left to manage antenna pointing per OTA station since in many areas (like mine), they don't all come in from the same direction.
