Hi Larry, You mention in the title '...Power Surge Advice.' I presume your KPA100 was working properly prior to not powering up?
You also describe the connection from your power supply to the KPA100 and then to the K2 - does this imply a Y-connection from the power supply to both the K2 and KPA100 since the units use different power connectors? Do you have an external fuse inline from the the power supply to the KPA100 and separately the K2? The KPA100 has no visual indication of power-up status unless you added some indicator in its external enclosure - how do you know it is not powering up? I would disconnect the power supply from both units, measure the open-circuit terminal voltage, then connect only the K2 to the power supply and your antenna (bypass the KPA100). Verify that the base K2/10 works as before. Check your cables from the power supply to the KPA100 and K2 for low resistance - and be sure that the Anderson PowerPoles are fully seated in the KPA100 connector. I would measure the resistance at the KPA100 power connector - in the normal polarity it should read a high resistance, in the other polarity it should read a low resistance due to the reverse polarity protection diode. Please let us know your findings. 73, Mike, K8CN ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
