I try to get a K3/100 - K3/0-Mini running with RRC1258. Using original cable kit on both sides from Elecraft.
K3/100 is connected to PS ( K3 is switched off and PS is ON)
If i connect the cable from K3 ACC connector to the I/O connector of RRC then K3 switched on. RRC ist not(!) connected to any PS, no(!) other cable connected.
Then i try and ground (-) PIN 8 of K3 ACC (it's PIN5 at RRC I/O) and K3 switch on.
[...from K3 manual: Remote Power On/Off A remote-control system can pull the POWER ON
line to ground (ACC connector, pg. 18) to turn the K3 ON.]
I measure RRC PIN5 (RRC without any other cable or PS connection) = its on ground (-)
My question: there are any pull down resistor (R123 ?) in RRC at this PIN 5 - any workaround or Jumper?

If you mean that the K3 starts, if you connect the RRC to it when the RRC is not connected to power supply, that's normal. R123 is not a pulldown but the transistor has a resistance which is low enough to start the K3 if it's uncontrolled. Maybe a resistor in serial will help if it is a problem for you

Hi
You have right D10 should not have been mounted when the Relay is not mounted. I will change it in the BOM for the next production batch. No one have recognized it before, thank you.

Mitch told me .... some hundred of K3 RemoteRig running without modifications.
Do i have a old revision? On other hand actual manual shows always : D10 is not removed!
Dont know what i have to do

D10 is removed some years ago, if you have and old version with D10 still there, remove it

Thanks Mike,
that was the solution: removing D10
Thanks for help
