Hello Calvin, Welcome to the Elecraft List.
Were you using a dummy load or your antenna when looking at your K2's output with an Oscilloscope? Is the frequency of the modulation/ ripple which you see equal to the sidetone frequency, or a harmonic of the sidetone's frequency, which you are using when transmitting CW? Also, if you transmit CW on another frequency in the 40m band, say 7.030 MHz, using the same power 10 watts, is the ripple still the same, any "weaker", or not there at all? And lastly, do you see the ripple on all bands, or on some bands but not others, or only on 40m? Sorry for asking these many questions, but there are several possible resons why the ripple is there. 73, Geoff LX2AO On October 22, 2012 at 5:04 AM, Calvin Jones wrote: > Hello, First time posting to the list. > > Completed K2 #7239 today.
