Stave, you are correct, it is the antenna alarm which I never use. As to sound, it is constant and sounds like a turn signal and it shuts off when the ignition is turned off. I raised and lowered the antenna, no change. Did it again but this time I moved it around, lowered it and the alarm went off. This is until I hit another rough road. Tomorrow I will see if I can reset the antenna lower or disconnect the alarm, once I find it. Thanks for hitting the nail on the head.
