First, ensure you are tuning into a 50 ohm dummy load. The K2 power calculations are based on the assumption that there is exactly a 50 ohm load. The initial dummy loads I was using, once I checked them with an analyzer, were off by a bit. I found one showing 50.1, and used that and the rig responded much more as expected.
That being said, the K2 isn't the most stable from a power output perspective. As I have been using mine a bit, and have the amp and the tuner, I set it to a power level a go. Not often watching it as I make changes. As memory serves, there is also some concerns, as far as how the rig is brought into the continuous power mode for measurements. Might want to take a look at the archives. - David Wilburn [EMAIL PROTECTED] K4DGW K2 S/N 5982 On Mon, 2007-11-12 at 12:17 +0000, Euan wrote: > I've just completed s/n 6222 (no ATU yet)and have a question concerning > tuning with a dummy load.
