[Elecraft] The Technical Side of Ham Radio

Ham radio is a hobby for those who are willing to learn about how radio works. To obtain a license, we must pass a test that shows we know the fundamentals of radio and electronics. Some don't bother to do that, but instead cram by memorizing answers to a lot multiple guess questions. I view

Let’s make sure the K3 and KPA are communicating. When you power on the KPA, does the K3 indicate that something changed? It should display the KPA power event on the display. If not: * what cable are you using between the K3 and the KPA? * Check the RADIO setting in the KPA. It should be set to

More data points: I usually use FixMode set to 'static' and FixTrack set to 'Fixed tune mode'. I don't know how that factors in... It may be another cause, but by cycling FixTrack, I can get it to display properly AFTER I recenter the display to start over again. This happens consistently
