We are getting radios, etc. into an area where they are requiring more and more addons which get slow to being a computer. So when things are not shut down/operated as the computers thinks, things do get a bit odd.
In an RV, the power does do strange things at time as we move and change.
We had an old saying where I worked. We know what things do when they are working right but when they are working wrong, they can do anything they feel like!
