Attention KX2 owners / users!

From Wayne N6KR on QRP-L this morning:

The latest KX2 field-test firmware allows power output to be set as high as 12 watts on 80 through 20 meters. (Max out is still 10 watts on 17-10 meters.) Supply voltage must be 12.8 V or higher on key-down. ~14 V supply recommended.

Yes, this is only about 1 dB, but it did help me snag XF1IM this morning on 20 CW.

We consider the change experimental at this point. Not all KX2s are guaranteed to hit 12 W on all of these bands, and this level is recommended for low duty-cycle use, i.e. hunt/pounce.

If you’d like to give it a try, please email me directly. (Editor's note: [email protected])

So there you have it from The Man, himself!

    Just a observation.. After reading a number of posting by Wayne and hearing some podcasts, I have come to the conclusion that he still likes the KX3, but his new love of his life is the KX2… Could be wrong… But then again I could be right.

    In my case I really liked my KX3 (S/N 00064). Used it at home, on picnics, in the woods and on trips… Then I got the KX2… It was love and lust… So much so that when I was given the chance to do a straight trade for IC-7300 I took it… Now I only have the KX2 and it is a real keeper…

    Where can we download the firmware to gain 12 Watt output?
