Thanks for the tip. I predict your 722 will have no issues.
As for my 612, this box is just plain weird. I had the opposite problem as you and the guy with the 622; when scanning with a 10dB distribution amp in the attic, channels 7 and 9 were the only
channels I got! With or without the amp, the SS of these stations was coming in at around 80-90. Possibly I could add the UHF channels manually using your technique, though that's a PITA since I have two of these receivers. I would really like to use that distribution amp, since the total number of stations I can tune on most
of my tuners is greatest with it in.
With the distribution amp, most of the DC stations were pegged at 100 on my SS meters, and I could at least scan in the Baltimore stations and MHz 6-10 (RF30). I live in Annandale. Without the amp, I don't see Baltimore and I don't see Goldvein (RF30).
My location is ideal for a dipole, because RF30 is in the opposite direction as the DC stations, with RF24 (MHz 1-5 only 2 miles away) parked near a null at 90 deg.
The problem is I chose a Winegard batwing antenna that is only a dipole at VHF frequencies; plus MHz 6-10 is coming off the back and passing through my roof twice. Obviously I should try swinging it around to point at Goldvein, and put the amp back in to see what happens.
What mystifies me is that I had no problem scanning in these channels before
the transition with any of my Dish receivers. A lot of channels disappeared, and WNVC appeared but (as planned) near a null of the antenna. WNVC is not
overloading that amp. I think something else
came on strong that I can't see with ATSC tuners, that is smashing my 612 tuner. FM perhaps?
