Doug, I guess you are seeing the Voltage drop on the power lead and it's connectors. With my "not so old" Racal linear power supply, I obtained the following results from the metering on the K3:
Zero out, 13.8V 5 Watts out, 13.5V 100 Watts out, 13.3V This was checked into a 50 Ohm load on both 80m and 20m 73 Dave, G4AON K3/100 #80 --------------------- After reading the recent comments on POWER OUT, I decided to check mine. Using the voltmeter on the K3.... Zero power out: 13.6v 5 watts out: 13.3v 100 watts out: 13.1v The drop from 13.6 to 13.1 for 100w doesn't seem so bad. But why the drop when running only 5 watts out...seems out of line compared to the 100w level drop. Does the 5 watt output V drop seem right to you? Comments? PS is 25-30 year old Astron RS35A Thanks, Doug KR2Q _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
