[Elecraft] K3 Shuts Off On High Power-HELP!

[-.-. --.-N3TU -.-. --.-]

I talked to Elecraft and they said it could my 18 year old power supply is going. I am due for one anyway and hopefully it will work right again.

Just running 100W on 1.812 MHz & 14.2V at the K3 drew around 17-18A 

from my Astron.


3.525 MHz draws the same


25-30 amps isn't right.


Wish I could be of more help.
