[Elecraft] K3 - why SWR change with an amplifier

[Don Wilhelm]

Jorge,

With the amplifier in standby, the K3 wattmeter sees the antenna SWR - 
the same as when the antenna is connected to the K3.
When the amp is switched to operate, the K3 will see the input SWR of 
the amplifier - and that has no relationship with the antenna.
