I took the A/B switch out and directly connected the antenna that picks up 11.1 ABC and am still having reception problems.
It gives me a strength reading of around 75 out of 100 when I use to get 84. A 75 would be fine but it drops to 49 % unexpectedly locking up the station. Acts like ghosting but when I view the Analog version OTA the picture is almost perfect with no ghosts or snow. It sure is strange considering that both the NTSC and the ATSC appear to be coming from the same tower.
In addition all other stations that I receive with that antenna are the same signal strength as they always were.
Maybe ABC is not trasmitting at full power.
On another note ATSC WB 22 was acting odd last night. It would toggle between the show with some odd rectangular artifacts in the upper left corner and a still image with vertical color bars and the following words:

Tha antenna I am using is a 4228 mounted in a fixed position in the attic with a booster from Home Depot. Can't recieve any decent signal with the booster out of the circuit.
