Syd, The best way to attack a problem like that is to determine what is working and what is not. I suggest the following procedure (sll while driving a dummy load: 1) Test the power output and power control of the base K2 - power via the coaxial power jack on the lower rear panel wither the KPA100 completely removed. If OK, then the base K2 is working and you can move on to the next step. 2) Connect the KPA100 cables, but do not power the KPA100 (no cable in the APP connector). It is also helpful at this point to connect an external wattmeter between the KPA100 antenna jack and the dummy load. This tests the wattmeter function in the KPA100 - do the same as you did for the base K2 alone. If you cannot control power or the power indication is wildly different than the external wattmeter, then the wattmeter section of the KPA100 needs work. 3) Connect power to the KPA100 and again test the power output using TUNE and TUNE-DISPLAY.
These steps should reveal what needs to be examined in detail. 73, Don W3FPR syd smith wrote: > > > Yep ... I did it.
