Chris,
That measurement of MDS can be done using a signal generator having a
calibrated 1 uV output level, such as the Elecraft XG1/XG2/XG3. See page
22 of the KX3 Owner's Manual, right hand column.
For how to use a 1 uV level information, refer to the method and formula
in the XG1, XG2, or XG3 signal generator manuals.
The use of a level less than 1 uV is also possible, but requires a very
well shielded signal generator and a very well shielded attenuator (many
signal generators have too much leakage). Duplicate the signal generator
setup used by the ARRL for MDS testing (the setup information is
available at ARRL.org) - the KX3 dBV alternate VFO B display can still
be used to indicate the KX3 audio output.

Hi all,
How to measure the sensitivity as given in the user manual using a
lab-grade RF signal generator and KX3 itself ?
