My receiver (vip 211) has been having trouble seeing the 129 lately. It can be a perfectly clear day, no rain, wind, or otherwise, and the 129's signal strength will be in the red. When I run a check switch, the 129 says "reception error" while the other two sats are working fine. Then the next day, the 129 will be back and running and I can receive channels that I wasn't getting the day before. This comes and goes in cycles. Has anyone else experienced this? Could this be a receiver problem?
