On the issue of the translator invasion:
There are certain requirements the FCC sets for where and if a translator can happen at a certain spot. The rules allow this. Some, it seems, feel because a translator interferes with their DXing, it must be illegal or at least immoral.
The people/organizations that are applying for these stations are doing so and getting granted. It doesn't matter if they have 1 or 10, it is okay if they meet the rules and to do that they get approved and licensed by the FCC. What it boils down to, there are doers and talkers. The doers do it. The talkers talk about it and some of the talkers become complainers, I suppose, because they weren't a doer and missed out. Any qualified person can have a translator.
There are lots of reasons for having a translator. In fact, with the non-commercial broadcaster, there is a certain amount of horsetrading that happens. You might get a station in an area that does not make sense for them, so might another group, so they trade to get that worked out.
For certain, the translator invasion is not over. It is just getting started. For some places, there might be nothing left on the dial. I suspect by the end of the filings, that list of places will be much longer. There will be losers and winners.
Translators are leased, bought and sold. Any entity that chooses to will lease buy or file for a translator if they have a purpose to do so. You actually can lease or buy a translator and you can choose the station it rebroadcasts within FCC Rules.
