HI, I have just fitted the DSP board and it works fine, on putting the K2 back together, I fond that 160M will not go above 50 Watts and I get a high current warning, All other bands are 111 Watts no problem. I am using Rohde & Schwarz power probe and a 40dB attenuator, to the match is close to 50 OHMS. I have also used my bird through line and get the same results. I suspected the band pass filter in the KPA 100, I did find what looked a poor joint on L1, but re soldering has not cured the problem. I do not like disturbing the PCB and power transistor mounts so need to pinpoint quickly. In QRP mode the K2 works fine. ( 6 Watts 1800 to 2.000 with 11 watts at 1900 I have never had 10 Watts + on this band). I will sweep the low pass filter tonight, if I find this in order, I will then connect the Watt meter directly to input to the low pass filter and see if everything is fine at this point. Has any one had this before and can give some pointers it would be appreciated? The SWR circuit gives 1:1 into the dummy load so is metering correctly. Has anyone know C2A, C2B, C2C, C2C, C2D, or CDE to fail or indeed L1 and L2
