[Elecraft] KPA1500 TX Sample

[David Box]

Was fairly certain that units were used incorrect but ya' never know so 
appreciate confirmation.

Wanting to get linearity test ready so now I know what is needed to set 
up.  I always want to monitor a new amp and the inclusion of this output 
allows that.

Now I do have one other "assumption" and that is the coupler is before 
the internal ATU so it is always working with a 50 ohm load, hopefully 
that is correct.
