Re: [Elecraft] K3 Power Supply Question

Folks - thanks for all the input. I think I may have found one of the culprits in the system - oxidation. I put everything back together the way it was to begin with so I could switch back and forth between the K3 and KX3 power displays. I have a KXPA100 behind the KX3 so the load on the MFJ

I connect my voltage boost, like yours a N8XJK, between the power supply mess and the K3. (I run it in RF Enabled mode.) That results in my K3 getting the voltage it needs, and the voltage loss in all the other connections getting made up. 73 Bill AE6JV On 3/9/17 at 9:00 PM, w6...@me.com

They are probably not providing assembled for the same reason that they don't provide it with the K2/100... it's a kit. It is NOT necessary to buy the expensive crimping tool. There are instructions contained in each KIT describing how the connectors can be assembled without using a crimp.
