If you or anyone else ever takes a look at my Google Map, note the black dots in TX/OK. Those are either new site licenses or licenses with updated site locations / added frequencies. If one would go by what was seen as Ohio was being built out, The FCC license modifications and such were very suggestive of what sitess might be coming online. Sure, many sites had no changes at the FCC (other than emissions perhaps). But, I know that in Ohio they seemed to go after sites that were recently updated at the FCC first, for the most part.
So, even if there aren't sites online yet, I would expect them to be sporadically popping up pretty soon, especially in those areas of OK/TX where you see black dots.
WX5UIF has seen two sites in his area come online -- one has been online for a long long time (Leonard). Neither of those sites broadcasts neighbors currently, but nonetheless they are lit. So if you do come upon a site but it has no neighbors, people should still scan all of 854-862 mhz for any other potential online sites. in the area.
I have no way of knowing who are the usual sleuthers in OK or TX (other than WX5UIF). But my suggestion is that if anyone knows those kinds of people in OK/TX (who use things like Pro96Com / Unitrunker / DSDPlus and can check for new sites), you might want to put them on alert and give them a link to the map. Without letting people know about this thread in the MultiState forum, there are a lot of potential sleuthers out there who likely aren't even aware to be on the lookout.
