[Elecraft] W2 Question about SWR Reading

[goldtr8 at charter.net]

I have been using my W2 for about a week now and I am trying to 
understand why it is doing what it is doing.

Basically I can get my SWR reading tuned in fine using normal tuning 
procedures and then turn on the amp and whistle in it and the SWR 
changes very little.

However when I go to TX using phone it bounces all over the place and 
goes signficanlty higher than I would expect.   This bouncing effect is 
tuner engaged or no engaged with resonant areas of the antennas.

The sensor is between my antenna tuner and amp.   The amp kicks out with 
anything over 2:1 SWR (SGC Powercube).

This happens on all three of my antennas my 2wl 160m Loop, Alpha Delta 
Dipole and 75m vertical.

Now the meter on the tuner when tuner properly or resonant can sit still 
or move very little in these cases.  However the sensor is after the 
tuner and before the amp.

Anyway, I am thinking there is something to be learned about what this 
is telling me as I am guessing that those fast LED's give data faster 
than the needle of the meter can move.

So is this normal or is it pointing to a problem in my shack or antenna 
system that I need to look to correct.

Otherwise I have no problems at all in the shack or signal report 
problems.  I just have a conversation on Friday night on 40m where we 
were discussing TX signals and one guy with a pan adaptor said my signal 
looked perfect almost like a square wave 2.9 Khz wide no distorshion and 
it sounds great.  Compared to the guy we were trying to help who was 
overdriveing his radio so bad that he had what was described as an 
almost AM looking signal.

Anyway I am posting fishing for information on what this is telling me 
so I can be sure I have stuff working as well as I can.
