Hi Eric: I am not talking about a signal streghth or SWR meter as most
radio will have. It more like a scope or radar giving pattern
information on the reciving attena. I was wondering if there was a
device that could tell you from which dirrection and pattern the signal
comming from and how.

In the Now Your talking Book, their is a diagram of attenas patterns. I
thought their must be some kind of a device for giving this information.

I've seen too many WW2 movies. LOL!

SR, 73!

I presume you mean to display a frequency vs. signal strength graph...
the answer is yes -- they are called panoramic adaptors or
panadaptors. A more general device would be a spectrum analyzer, used
as a panadaptor.

You can expect to pay about $1500 for a new one, and at least one is
being made today. I bought one for about $100 and was only marginally
satisfied. I bought a spectrum analyzer for $300 that does a much
better job.
