This probably sounds silly and very low tech, but it worked for me before I got my HD package. I bought my HD tv earlier this year way before I ever got HD (just had regular D*), and hooked up a pair of rabbit ears (remember those?) to the antenna input on the tv, ran the tv through an OTA channel scan, and ended up picking up seven digital signals, two in 1080i, in addition to my regular OTA SD broadcasts. Since the NBC local is in HD, I still switch to that on Thursday nights since I don't get D* HD locals and I gotta see Tina Fey in all her glory.
