KAT2 high SWR problem..?

[Gil G.]

Hello,

I completed my K2 ATU, and everything checked out until the power-on test. With output power set at 5W, I only get 500mW out..

Where would I look first, T1 maybe?

Thanks,

Gil.

Gil,

When you say you completed your KAT2 build, did you complete all of the final calibration steps, specifically the bridge null adjustment (p. 16 of the KAT2 manual) and the power calibration adjustment (p. 17)?  I would be surprised if you could make those adjustments successfully and yet have the low output power you indicated into a good 50 ohm dummy load - a problem with T1 connections would be revealed during one or both of those adjustments if that were the source of difficulty.  Be sure that you also have selected on the K2 front panel the correct antenna port (Ant 1/2)  to which your dummy load is attached.
