Thanks for all the replies. At least I know I'm normal, er, well the radio is at least :) Had a good time with AA CW test this weekend just in and out of the shack an hour or two at a time and limiting myself to the K2 at 10 watts whilst the K3 and big Alpha sit idle. Very good to work into EU

Hi Bob, The K3s, KX3, and KX2 use a similar ALC power control design. John KN5L On 06/17/2018 07:47 AM, Bob McGraw K4TAX wrote: > I've noticed a bit of the same thing on my K3S.   Not an issue but I > view as a nice safety feature preventing overshoot and over drive of my > KPA500. > > 73 >

Martin, The K2 resets the power control mechanism after a band change or a change in the POWER control. To prevent overshoot, it starts out low and ramps up quickly to the requested power. It must sense the actual power output and adjust the drive accordingly, and that takes one or two dit ti

Hi Martin, The power ramp up is normal behavior. The K2 uses requested power control (Page 92, "Requested vs. Actual Power:" paragraph) With a per band set value (Page 111, "Microcontroller" paragraph, "ALC, which is used on CW to maintain the user-specified power level across all bands.") When

Having a lot of fun in the AA CW test, even with my ropey CW  using the barefoot K2/10. Definitely the beam at 80 feet helps but still it's great to be working JA and others on 21 and 28 MHz with just the 10 watts from my HS QTH. Since building the K2 it's been one of the first times I've been
