It seems like whenever I have to reboot my HR10, when it comes back up, OTA signal strength is significantly decreased. Then after a few days it climbs back up to 80+ on the stations that I'm close to. Could it be that the HR10 is working hard on re-populating the guide or something? It doesn't really make sense to me, but it happens every time. It's bad enough that I lose reception on several channels and I have to fiddle with the antenna (roof mount mast antenna with rotor) to get them back in. Any ideas or suggestions?
