I did more tests with both transistors today, adding 30M and 20M. Same setup as before, switching to the output transformer for the 4 and 5 watt tests, but then I thought why not check at the 3 watt level with and without the transformer--in most cases the gain was a little higher with the transformer. I didn't think of doing that until the 30M test, so the 40M data doesn't have that. Neither transistor will output 5 watts but I'm again surprised the lowly 2SD822 even puts out a little more at 20M than the 2SC5706.
Probably not many folks have much interest in any of this but I had fun doing the tests and it's easy to post the data.?? :)
