Someone wrote: "...in many respects the K2 does outperform other rigs, but unfortunately in terms of transmitted phase noise it does not. This is not an issue at low power, for which I think the K2 was originally designed, but becomes noticeable when the K2 is used to drive an external linear. My findings have been backed up by off reflector replies from others." ========== Over a year ago I noticed this problem, which occurs only when my K2 is driving my Alpha linear. After extensive testing done by me to determine the cause of the problem, is was found to be caused by hum from the magnetic field of the linear amplifier's HV transformer getting into the PLL circuit of the K2. In my case, 6 feet of separation between the K2 and the linear was not enough to eliminate the problem, however with 30 feet of separation (with the K2 and amp in separate rooms) did solve the problem. This answer is unacceptable, of course.
Wayne and Eric are aware of this problem, however my last several e-mails to them asking about their investigation into it have gone unanswered. Anyone want to buy a full-blown K2/100 that is perfect in every sense (except for this one problem which is inherent in all of them)? 73, de Earl, K6SE K2/100 #2622 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
