Your previous post was plenty clear.
You got two good answers.
There are no mods to DirecTV nor Dish receivers to make them into FTA receivers.
See previous post for what is "FTA".
I did not make any assumption you intended to "crack" the receiver to obtain pay-programming.
I have several of each brand of receivers.
The universal RCA remotes have been good to use on my RCA TV, and I've culled a few spare parts off some of the boards.
Since both companies will give you "free" receivers if you sign up, there isn't a large market for 4-year old hardware.
There have been several recent discussions on the forum of good FTA receivers going for as little as $35 on eBay.
If that interests you, we can help.
