Had a funny little experience with the V1 earlier today. Sitting in a parking lot, it insisted that there was a strong (5, 6-dot) Ka signal behind me. It had done this in the morning, as well as several hours later.
I turned it off and on - same thing.
Turned it off, got out the x50, and tried that - no Ka.
It (the Valentine) was also not detecting a K-band door opener that both it and the x50 always have - the x50 did, the V didn't. It also incorrectly designated it as X-band for a few seconds.
What is that all about? Is there a known heat issue with 3.821 or something? The x50 was fine through this, and that was the first time something like that has happened.
