[Elecraft] Internal Antenna Tuner and SPE Expert Amplifier Questions

[Don Wilhelm]

Mark,

The short answer is no.

The only way to reduce the SWR on an antenna is to connect the tuner 
between the antenna and the output of an amplifier.  That is where the 
SPE internal tuner is located.

The K3 internal tuner would only attempt to match any impedance 
difference between the K3 output and the amplifier input.  With a well 
designed amplifier, the input should be close to 50 ohms resistive and a 
tuner should not be needed at that point.

You may still have to use your Palstar tuner between the ampifier and 
the antenna if your SWR is in excess of 4.0.

> It's Mark Griffin KB3Z. I was looking at an SPE Expert amplifier and I see it has an internal antenna tuner which can handle SWR's of up to 4:0. But, I was wondering if I connected the output of my K3 to the input of the amplifier and then the antenna to the output of the amplifier, If I used the K3 internal antenna tuner to decrease the SWR to a reasonable level would this work? I don't currently have the internal antenna tuner in the K3. It is perhaps a bad question to ask, but I am currently using a Palstar AT2K as my antenna tuner. Any help or advice would be greatly appreciated.  Mark Griffin, KB3Z
