Well this was my first contest with the K2 at field day with the 100 watt module. I was really surpised at how cool it ran.
we ran 990 q's on CW only and the heatsink never even got warm. And that was with us calling the whole time. Got lots of complements on Reciever performance. And of course my response was it is a K2 what do you expect.
