Add me to the list of people experiencing the K2/KPA-100/KAT-100 40M high power reset problem.
Since my KAT-100 is built into the base of my K2/100 I do not have the option of moving the KAT-100 farther from the K2/100. One observation I made back when I was trying to track the problem down was that it did NOT seem to happen when I ran on a 12V car battery on my desktop but DID happen when I used my Astron 20A switching supply. It was not a conclusive test but I'll try again next week. How many others who are experiencing this erratic 40M behavior (resets the K2 etc) are also using switching supplies? Anyone having problems with a K2/100 and KAT-100 combo ONLY on 40M please contact me off-list and I'll keep track of all those who are affected by this problem. One person is a fluke, two people is a coincidence, three people is a trend and four or more people is a problematic symptom that needs looking into. - Tom K2TA ----- Original Message ----- From: "Ken K3IU" <[EMAIL PROTECTED]> To: <elecraft@mailman.qth.net> Sent: Sunday, May 14, 2006 8:28 AM Subject: [Elecraft] K2-100 Parasitic > I also have experienced this problem on 3 different K2/100s.
