[Elecraft] S-Meter Sensitivity

[Lyle Johnson]

Hello!

Unless you know your K2 input impedance is exactly 50-ohm resistive, you
should remember to put at least a 6dB (10 dB is better) attenuator between
your signal generator and your K2 receiver input jack.  Allow for this when
making your measurements.

If you just connect the generator up to the K2, you risk having significant
errors depending on the actual impedance at the signal frequency you are
using.  Not that it *really* matters, since the "S meter" is just an aid,
not an absolute measuring device :-)

Enjoy!
