I just finished reading the SPE instruction manual. They say that the input match of the SPE Expert is good enough that they recommend turning the internal tuner of the driving transceiver OFF. The recommend that you do not cascade a tuner such as the Palstar on the output of the SPE. They do not mention a manual tuner at the antenna, but I would think it to be OK as that is what a Gamma or T match on a beam would be, as well as other matching devices. I think that the intent is to use the SPE tuner even if you are running the K3 barefoot but I have not yet completed my installation and put my SPE Expert in service.

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.
