Hi Pat; What are the results of the 5w TX gain calibration running the K3 Utility? The LPAs are somewhat interchangeable, they don't always make full power in some cases. In any case, you MUST run the TX gain cal if you swap modules, so run it now and it should reveal problems. Keith WE6R Elecr

I have a problem on my K3S. Suddenly in SSB the radio started producing splatters. It is very evident when comparing with a K3. Trying with spectrum analyzer in CW the wave is perfect, the phase noise also ok. The problem persists excluding the KPA3A. The ALC control seems to be ok. It's likely a f
