DTVnotworking

Ive lost most of my channels after the switch like alot of other ppl in the country. I see alot of ppl in the los angeles area share same channel loses.. just wondering if anybody else in the Maryland DC area is having trouble getting channel 11 on theyre didgital TVs with tuners and ones with convertor boxes also.. wondering if theyre one of the stations operating at lower power levels since the switch to save on the electric bill. Because it was fine before friday and now I dont get it all on my large digital TV with built in tuner in the livingroom... can hardly get it on the TV i have in my bedroom with a magnavox convertor... it kind of comes in but its frozen but it does come in fine on my roomates tv in the other bedroom. Anybody else in the MD DC area having problems with WBAL channel 11?

Just noticed that channel 11 is coming in pretty good now on my bedroom TV when it was frozen all day... it was fine at one point the last couple days and then i couldnt get it all sometimes also... are the stations that are operating on lower power boosting it up at night or something?
