Re: [Elecraft] K3 Abberation
Paul, One possible explanation is if you currently have CW Keying enabled via your COM port AND you had just turned on your computer prior about the same time as turning on the rig. Your computer COM port randomly fires DTR/CTS signals on power-up which would present itself as you describe. If you don't use COM CW keying, I'm stumped. ;-) GL, Bob K5WA Message: 12 Date: Sun, 9 Dec 2012 14:41:49 -0800 (PST) From: Paul Gussow To: "elecraft@mailman.qth.net" Subject: [Elecraft] K3 Abberation Message-ID: <1355092909.4438.yahoomail...@web121301.mail.ne1.yahoo.com> Content-Type: text/plain; charset=iso-8859-1 Hi All, I've noticed an odd behavior on my K3.?

Re: [Elecraft] K3 Abberation
Further do David's suggestions - do you have an RS232 keying circuit keying the K3? If so, a component in that circuit could be starting to fail.

[Elecraft] K3 Abberation
Hi All, I've noticed an odd behavior on my K3. From the time power is applied, the TX light begins to flutter on and off in a random manner. When it's on, the K3 transmits, this in CW mode. It doesn't matter which band is selected. I've just recently installed firmware version 4.60, but this has been going on for a while. This condition lasts for as long as 45 seconds, then stops on its own (so far). ANY help will be very much appreciated!
