[Elecraft] A plug for one of Elecraft's lesser-known kits

[John Harper]

 Be sure to be aware of your device's maximum permissible input power level
(I'm not sure what it is for a tinySA). If measuring a 100W transmitter
with an analyzer whose maximum input level is 10mW, you'll need 10 dB more
attenuation - this could be in the form of a fixed attenuator on the output
of the directional coupler. Or, better yet, just turn the transmitter down
to a 10-watt (or less) output if using a 30dB coupler.
