[Elecraft] K2 S meter

[Rick Dettinger]

The S meter not only changes with the setting of the RF gain control, it =
also changes when the preamp is turned on.  With the preamp on, the S =
meter reads about 2 S units higher. =20
The S meter is most useful for relative measurements, such as comparing =
antennas.  This can be done on receive as "normal" antennas have =
reciprocal properties on transmit and receive.
Also, due to this reciprocity, the S meter readings for two stations in =
contact should  only very according to the power difference.  The =
antennas cancel out as long as the same antennas are used for transmit =
and receive.  This is true even if one station is using a large array =
and the other is using a dummey load!  Therefor, if you think the other =
op is giving you a "polite" report, you can determine what it should be =
by adjusting your S meter reading for the difference in power levels.  =
If you are using 5 watts and he is using 100 watts and your S meter =
reads S7 then you know that your signal is approx. S5.             73,   =
