Now that I have my radio back, but not on the boat yet (if ever :cry, I have decided to set a metric for power output vs power consumed.
I have three fixed levels of power on my radio; 10, 50, and 100 watts. Here is what I have measured using an Extech True RMS current clamp meter.
Kenwood TS-50S, 20 amp DC power supply, CW keydown (current draw rounded to nearest A/H)
RX - 1 A/H
TX 10W - 6 A/H
TX 50W - 13 A/H
TX 100W - 18 A/H
In SSB mode I noticed that at key down and voice peaks, the current was about the same as the preceeding value, i.e. 100W showed about the same at peaks as the 50W CW keydown and fluctuated.
I did not test for voltage drop. My PS is regulated so I doubt that would be a valid test. I will have to use a 12V battery to test for voltage drop.
