I have noticed when I fired up my amplifier on 40 meters that the SWR reading
on the K3 when I tune up is higher then when I tune up on standby. But what is
really odd is on my External Wattmeter the SWR is the same when the amp is
active versus standby. On standby my SWR on 40 meter SSB is
Mark,
Where do you have your external wattmeter? On the output side of the
amp? If so, then your external wattmeter and the K3 are reading the SWR
of your antenna system when the amp is on standby. When you put the
amplifier in-line, the K3 will read the input of the amplifier. In the

When a rig drives an amp, it does not see the antenna, it sees the
input circuit of the power
