Okay, since October last year I had my OTA antenna hooked up to a TiVo Roamio. But Wednesday next week I will be getting a splitter and my antenna will be hooked up to my AM21 as well as my TiVo. This way I won't have to change inputs on my TV so much, and since I don't have a TiVo Mini, I can watch OTA on my second TV as well. Now, if some of you don't already know, I live in Rochester, MN. With my pretty powerful antenna I can pick channels up from three markets. They are the Rochester and Austin, MN/Mason City IA market, and the Minneapolis and St. Paul, MN market and the La Crosse and Eau Claire, WI market. So what zip codes will work for the subchannels in those markets, as well as in some cases, the primaries. What order would I put them in? Do I put Rochester as the primary location on my AM21 for every market so the others would just be added as secondary (such as Rochester as a primary, and Minneapolis and the other zip codes for the subchannels as the secondaries)? Or would I, for example, use each market as it's own primary? It's been quite a long time ago since I've used my AM21, so I'd like to know. Thanks.
