Well, I'm not at present using a USALS dish, but you always have to load the local map coordinates on the receiver for USALS use one time. Then it calculates all the rest. So the setting must be there somewhere after choosing USALS.
@johnnynobody your STB was shipped with The North American Project, which is a mod of the SatDreamGR image. The TNAP image does not provide automatic updates and will not have the the latest files from the SatDreamGR repositories.For the most part, I like this image. But, I found that it needs additional repositories so that I can install OpenVPN on it like I can with OpenVIX. I've heard that an update to the SatDreamGR image that'll include additional repositories.
