I tried the direct wiring fix first. It didn’t change anything. And the voltage drop was radical. It would go down sometimes from 13 to 11 volts. The voltage drop was not indicated on the power supply volt meter. And remember, the big Astron power supply works fine with my IC-7300 and IC-746 off the Rig Runner strip. Maybe those rigs work better with the voltage variation. But something is going on here with either the power supple or the K3. I paid about $200 for the big power supply back in the 90’s. I think the little Astron supply (switching type) was less than $100. Maybe the difference is between transformers and switching technology. Anyway, my nightmare is over with a happy ending.

If it stays up, then check your power cable to the K3 for adequate size wire and good connections. If you have a DC power distribution device like the RigRunner, remove the K3 from it and connect direct from the power supply to the K3. ______________________________________________________________ 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
