JT,

Those all look good, but really do not tell us much - you have to be the
judge of when the peak of the signal has the greatest difference to the
noise floor.

You really should crank in a bit more soundcard gain - that will allow
you to see the noise floor across the entire screen rather than just in
the passband.  That is often helpful in making an overall judgment.
