I hope its not age in my case - my radar is less than 4 years old and I believe
I had this effect from the beginning.

I do see what you describe occasionally with a Raytheon SR 70. I never

previous Furuno 1720.

I don't think it indicates an active radar on the target, because I
have had it happen with big rocks. It usually goes away pretty soon.

Hmmm, sounds like maybe your Magnitron is getting old. Been know to
cause mutiple echo's from a single boat, or rock. If they are infront
of and behind the real target, it is reflections. If it is right or left,
could be what is known as Multiple Pulsing.
