I tried this last night in Missouri and Oklahoma, probably fifty times,(I'm OCD and had nothing better to do, lost count), no dice...tried it twice this afternoon while driving thru Austin Texas, whammo! Seems to be a solid signal, and no data dropping (blue bars) like before. I get around, so I'll be giving it the official road test the next few days, and I'll be home in northern Indiana on Wed, where we've always had problems at our home, but okay signals out in public...
