You are probably correct concerning a 3:1 SWR. Transmitters
usually have to meet full output into a 2:1 SWR, all phases, with no
sign of oscillation. In this case I had assumed that a matching network
would be used between the PA and coaxial input.

Everything I have ever ran can handle 2:1 quite nicely, with
transistors, I worry about exceeding that ... or, how big is your
heatsink/fan?
