Hi Mike,
What are your voltage readings at the power supply end of your six foot power cords? None of my K3s do behave the way you describe. 73 Frank W3LPL ----- Original Message ----- From: "mjpilgrim" <[email protected]> To: [email protected] Sent: Monday, February 25, 2019 6:55:01 PM Subject: [Elecraft] K3/100 Voltage Drop when transmitting At first i suspected my Solar power system which was installed a year ago, but now I plugged my K3 S/N 7317 directly into my 25A switching DC power supply, and when key down, 100W in CW, on the internal K3 Power Meter i see a voltage drop from 13.6 to 12.0VDC. My power cord is a 6', 10ga stranded copper wire pair with Andersen Power Pole connectors. I have tried three separate power cords, all 10ga with power pole connectors, but with no change in the voltage drop scenario. If anyone has suggestions of where the problem lies, I am all ears. Obviously, when operating SSB the drop is present but not as severe. What am i dealing with? Better yet, how do i fix it? Thanks in advance.
