I'm in the Chicagoland market, EA, 722k DVR, & never checked spotbeams until a few months ago. But when I did/do they all seem to take anywhere from 15 to 30 seconds. Yet when changing channels there is no appreciable delay.
I don't know if this is related, but going back several months ago when I looked at System Info the screen displayed Green squares for 77 & 72, but either Yellow or Red for 61.5. A tech came out said it was an LNB problem & installed a new one, but it made no difference. He looked at Check Switch & SS & everything was OK, but had no explanation why I had Yellow or Red for 61.5.
My friend about 20 miles away with the same setup (722k, EA) still gets all 3 Green, yet some of his SS are lower than mine. However my neighbor (EA but a receiver only) got Yellow for 61.5 when I went over there checked.
Short story, another Tech came out & said the Yellow or Red in System Info for 61.5 did not mean anything.
A third tech said this was not normal & tweaked the Dish alignment but it made no difference. He suggested changing to the 1000.2 Dish & LNB which only uses 72 & 61.5 since there is nothing on 77 that I subscribe to. He proceeded to change the Dish. While the individual SS went up slightly, System Info still shows Yellow or Red for 61.5, and it still takes up to about 30 seconds for spotbeams to lock. But again there is no appreciable delay changing local channels (only 1 or 2 seconds).
So far there is no explanation why System Info shows Yellow or Red for 61.5 or why the spotbeams take so long to lock.
