I've got zero signal strength on all of the even transponders for the 103* (s, ca, and cb) satellite. This problem doesn't happen all the time - sometimes there is signal but there hasn't been any signal for the last couple days. Any idea how I can go about troubleshooting this? Today I compared to a neighbor's signals and they've got 90's where I have 0's - but they don't have a SWM like I do so I don't know if that is meaningful. Any advice would be appreciated.
