Not really standard. No, it's not the "HD enabling fee" that shows up if you have HD equipment and no HD programming. This "leased receiver fee" of $7 (increased recently from $6) generally shows up on customer accounts where receivers have been upgraded (ie Dishn' It Up). Even if that upgrade replaces the only receiver on the account.
As far as I'm aware, it can be waived for a period of time, but not removed. At least not with the reps I've spoken with. If anyone has been able to get it removed, please share

It really is a total junk fee - you could sign up for new service today and get the same equipment and same programming and not be charged that $7 fee. If it was enforced more fairly (only for the contract duration immediately after upgrading) or consistently (for all customers with that package/equipment, like the DVR fee) it'd be tolerable. It's neither of those, in my opinion.
