[Elecraft] KX3 sensitivity check

[Don Wilhelm]

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.

73,
