[Elecraft] Higher SWR When Using Amp.

[Don Wilhelm]

  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 
meantime your external wattmeter is still reading the antenna system, 
and should not be expected to change.

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 1.0 to 1.  When I tune the Amp it goes up to 1.6 to 1.  I realize that it isn't that high but just would like to know if there is an explanation as to why this occurs.  Mark KB3Z
