Thanks for replying Patrick.
This is the part I don't understand and am trying to clear up.
When you say that Doppler radar "treats the *received* signal"...
are you saying that Doppler radar does not transmit signals?
^^^^^^^^
WHAT is transmitting the *received* signal you refer to?
I thought radar transmitted a signal and then received a "bounce".
As I say in my original post, I'm a layman.

If the Doppler radar, does not transmit (at 5 million WATTS)
and only receives nature's "signals" and interprets, processes them,
then I feel a whole heck of a lot better about living near
this huge tower with the massive 35-40 feet diameter globe on top...
if all it is, is a receiver dish and NOT a transmitter.

That's the MWatt the newspaper reported, close to 5 Megs of Watts.
So, you are saying that all these watts are contained in that
tower and station below for receiving and processing purposes only,
and are not the power used for transmitting purposes?
