I know SWM-16's run hot, but I just measured mine at 168.5° F. It's on the west side of my house, and the afternoon sun beats down on it. Is this something I should worry about, or is this OK? I don't think it an issue with this particular SWM-16, it's brand new and the old one ran at the same temp. I was experiencing intermittent loss of all even transponders. The tech replaced the SWM-16, and when that didn't fix it, he replaced the LNB.
