Thanks for the tip on the diagnostic tool. I found it's a good idea to keep tabs on the signal strength since we just have an indoor antennae and weather conditions can mess things up for one channel from time to time. So, if we are recording one or two shows on that network, we can make adjustments for that evening. Not ideal, but until I can get a roof antennae with a remote, I'll make do. It's not all the time, but it does happen.Just curious, why do you have a frequent need to check signal strengths? If you don't want to go to the actual signal meter screen, you can also view signal strengths by going to the Diagnostics screen. This will show you the strength for any channels that are currently tuned.
