Problem with 510 and 105

[JOprandi]

My 501 started acting up about a week ago. The signal strength on 105 transponder 10 (where my locals are located) is <30. 119 and 110 are very strong.

My 811 and 4900 are both showing a signal strength of 61 for 105 and have no problems with the locals.

Any suggestions?????

Bad connecton, take all connections going to the 501 apart. Check for loose connector or corrosion.
