Wayne all I can say is wow! I knew the K3 was good but I had no idea it was that much better. Let's hope the other manufactures adopt the most sincere form of flattery... they copy the K3. After all that benefits all listeners.
My question relates to Matt's use of a battery booster. In theory this allows the K3 to use maximum feedback and therefore have an even cleaner signal. However my experience with battery boosters, not necessarily the one Matt uses, is they are dirty in terms of electrical noise. The lower the input voltage the dirtier they get. What is the K3s sensitivity to power input noise. In short is the battery booster concept a net gain in terms of spectral purity? 73 Fred, AE6QL -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Wayne Burdick Sent: Monday, January 19, 2015 9:22 AM To: Kjeld Holm Cc: [email protected] Subject: Re: [Elecraft] K3 cleanest signal possible Hi Kel, The K3/100's phase noise and ALC artifacts are so low at all power levels that you shouldn't need to finesse this. I would select power level based on what you want to get out of the amp.
