sobonefnet - Since you're in Altoona you have several HD and SD channels available to you over the air - have you tried any of those yet? I know you can get 24.1, 24.2, and 24.3 (WATM ABC HD and SD and WWCP FOX SD, respectively) and also 32.2 (WTAJ CBS SD). I get the Ch 24 stuff well and once got 32.2 as well, but that one has disappeared for me. You probably can also get 34.1 and 34.2 (WJAC NBC HD and SD). Those I can't get at all, 55+ miles from me. You might also try 15.2, .2, .3 WPSU PBS. I get those very well!
If you can find out what happened to 32.2 let me know (they're not answering my e-mails). Also - when will they start b'casting HD ??
TIA and have great weekend...
