Thanks guys, The Toshiba is 8 yrs old & still won't get ch12 with or w/o the amp, direct from the attic antenna without the system.
All signals are between -50 & -40 dBs, all the sets are within 60' RG6 of antenna and I'm pretty far from the metro.
Brad got me thinking about the older tuner so I checked the menu & I noticed that the physical channel number was different than on the other sets somehow & only for PBS. When I tuned up to the next slot there it was - all 3 PBS subs. I have no idea how it changed and didn't affect the newer sets, but when I re-scanned, they all came back. It's as if the other 3 tuners saw the move & corrected the virtual channel for it? The Toshiba is still terrible but now gets the same broadcasts.
Another 2 pair of eyes ! Thanks for the kick.
