The power control will not reduce power if the forward power measurement circuit is not receiving power. As it is after the bandpass filters and that is where the problem seems to be. Currently the power is only controlled by the current limit settings to the CPU.
I suggest signal tracing in SSB and adding only a small audio signal to limit the power loading to reduce the load on the PA transistors.
This is why I brought this up earlier.
All of the above is from perhaps incorrect recollection, however. I do believe that this is the case. Power cannot be turned down if the forward power measuring circuit does not sent the power level back to the CPU.
