I just finished installing the KAT2 and in testing discovered that power output begins dropping on 15 mtrs. I removed the KAT2 and tested the plain K2 into a dummy load, with the same results. I redid the transmitter alignment but it didn't change the results, which are, with a 10 watt setting: 80 mtrs: 10 watts 40 mtrs: 10 watts 30 mtrs: 10 watts 20 mtrs: 10 watts 17 mtrs: 8 watts 15 mtrs: 3 watts 12 mtrs: 1.5 watts 10 mtrs: 1.5 watts 160 mtrs; 1 watt
There is no high current with any of these readings--it is about what you would expect for the power output listed. An external meter between the radio and dummy load confirms the K2 internal meter. It appears that the drive is tapering off, but I'm at a loss for what would cause that. Power supply is 13.8 volts, indicating 13.3 on K2 display and never dropping below 13v. This is a pretty much loaded radio with SSB, DSP, NB, 160 meter option--pretty much everything but the KIO2, 60 meters and transverters, and has been in use as a K2/100 for several years delivering expected output on all bands. I just recently pulled the KPA100 out of it to convert it back to QRP. Where do i start and what do I look for?
