Hi Don,
I use my SPE Expert 1K-FA with my barefoot K3. I get around 900Wout on HF
and about 500W on 6M. It's a great combination as the K3 talks to the SPE
and everything is transparent including the SPE's built in autotuner.
The SPE display reports over 18dB gain. It has been type accepted and sold
by SteppIR.
