Dave,
You can use the Alternate VFO B display of AFV to give better resolution
than the S-meter. See page 36 of the K3 manual. You must have the
CONFIG: TECH MODE turned on to show the AFV entry.
If you want to see the difference between two values, there is also the
DBV alternate VFO B display which will show the difference in dB between
2 noise or signal settings.

I currently live in a townhouse and have made an offer on a few acres in a
more rural area. I would like to measure the relative noise levels between
the two locations to reduce the probability of surprises or disappointments
should I close the deal. I have gotten access to a very good battery
powered spectrum analyzer and plan to use a tripod-mounted 6 foot whip and a
20 dB LNA to measure the noise levels at each location.
While setting this up, I though it would be interesting to try to also use
the K3 to measure noise with the same antenna (but without the LNA). I've
written a Python script to control the K3 as it steps through each band and
records S meter levels.
I'm looking for recommendations on K3 settings for this purpose. Specific
questions I have are:
