When I first connected my Surecom SW-102 and a 100W dummy load to my DB25-G with a standalone power supply, I was pretty disappointed with what I saw. It peaks at about 13.9W (it is marketed as a 25W radio), and then falls from there. So I wanted to take more measurements, and compare them to other radios to see if something other than the DB25-G is at fault... and my reaction is "say it isn't so!"
This evening I spent about 2–3 hours taking measurements with all of my radios. For each channel, going in order from left-to-right as listed in the table of readings below, I would transmit for about 60–75 seconds, and the number I would record is part the power reading I saw the most of that time (the mode), part the average (so the number is slightly subjective). There would be only a brief break in between each trial; except for the DB25-G where I would wait for the fan to spin down completely, which I would guess takes less than 10 seconds. VSWR with the dummy load varied between 1.00–1.03, and VSWR of the antenna got as high as 1.77; though I was not paying too much attention to it throughout all the trials. Let me know if I need to provide more information on my testing "methodology" and/or my equipment.
Is there anything weird about these readings (other than that the UV-5R Plus was surprisingly consistent compared to all the others)? Why am I not getting a reading from the 0.5W channels on my KG-935G? And, most importantly, is my DB25-G underperforming?
