Just called to try to get a tech out since my 129 always sits at about 12-14 for signal strength. Over the phone they had me run check switch and magically my reception is 20-25 now.
What does check switch do?
Running a check switch, should not have increased your signal strength.
For the most part, check switch tests and confirms the configuration (cabling routing/connections) between your dish antenna and receiver, is properly connected.
As you saw, after a successful switch check is run, the receiver reboots.
It is possible the switch check found some sort of error, which it corrected, or something else was corrected during the reboot phase, which may explain the increase in signal.
KIM, when checking signal strengths, each transponder on a particular satellite will differ. You may have looked at the signal strength of one transponder the first time, and another the second time. In order to correctly determine the signal strength of a particular satellite, you should check several transponders on that satellite, and the average the sum.
