i am new to HD radio and have never played around with one. i'd like to treat myself to one but am afraid that where i live, i won't pick anything up. i'm pretty rural and although i'm in pennsylvania, am still a good 80 or so miles as the crow flies to philadelphia ... about 40 miles to allentown ... about 50 miles to harrisburg ... about 60 miles to scranton/wilkes-barre. and those are the nearest cities i know of with any stations that even broadcast in HD. so is it worth it even for me to buy one? why isn't there any HD coverage map sites online like there is for analogue radio (radio-locator).
