[Elecraft] [K3] Tokyo High Power

[Dave & Jeanne Robertson]

Does anyone use the Tokyo High Power linear amp (HL-1.5kfx) with their K3? If you do I need to ask how you connect the auto band switching to the linear with the K3?

The manual doesn't refer to the K3 at all but refers to Kenwood. It appears to use a Serial connection from the rig to the amp and is restricted to 9600 baud comm speed.  I have a P3 and it requires a 38400 baud connection. For a test I tried to change the baud rate to 9600 only to have the K3 change it back to 38400 (note the P3 is connected during this time). It appears that you cannot use the P3 at the same time you use auto band switching in the THP linear. Am I correct in this assumption and if I am not could you please enlighten me.
Thanks in advance.
