This thread has lead me to notice the comments on operating voltage. I’ve been having some trouble with my K-3 and the MCU LD message on startup. It was suggested that I monitor the voltage on the rig during operation. I get the 13.5 on receive. But the voltage drops as low as 10.5 on 100 watt transmit. I have an Astron power supply that is rated at 35 amps, very conservative for this usage. I have used it to power 100 watt rigs in the past with no problem.
Is it normal to register voltage as low as I’m seeing on my K-3? The power supply has meters for amps and volts and the voltage indicated during power cycles is unchanged. So it appears the voltage drop is at the rig. I can ever see dimming of the dial light in some situations. I don’t think the power supply is failing since I don’t notice these symptoms with any other rigs. And no, I never use the power supply for more than one rig at a time.

I learned where the pot was at HAMCOM, and the first thing I did when I got home was adjust it to provide the K3s 13.8. ______________________________________________________________ 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
