I was able to talk to the engineer at my NBC affiliate (the other 3 were approved, NBC was denied, D* told me) and explained the terrain around my house and he agreed that the terrain and distance (~65 miles) would make it very tough to get their HD signal, which isn't at full strength yet. He approved the waivers and transferred me to a secretary to get my info to send to D*. She looked it up and told me I had already been approved, twice in fact. She was nice enough to fax the info to D* and made a follow-up call to D* to make sure they got me hooked up.
This little experience told me that D* was not processsing the waiver properly. Why NBC was 'dropped' twice is beyond me. All the towers are at the some location and NBC is the weakest of the 4. It seemed really weird that they were the one not approved.
So, my point is, see if the stations have the engineers info online and call and ask to speak to him/her. Be very courteous and calm and just explain that you would be very happy to watch the local broadcast if you could, but that you would really appreciate if you could get waivers, at least for HD. (This is a total BS line, as they don't grant waivers based on analog/digital/HD, but it makes you sound a little more sympathetic.)
It's worth a try, just remember, they are doing you a favor. (You catch more flies with sugar than vinegar, or whatever that is.)
You can still get waivers, there have been cases reported here. As far as getting both feeds, you need to be in an O&O area or a total white area (no ATO service at all). In almost all cases now, if you do get waivers, you will generally get just E or W, not both.
