<div>Many people have reported trouble getting the MK2R+ to reliably stay connected to a K3 while running Win-Test. Part of the problem may be that Win-Test, unlike Writelog, polls the K3 as fast as it possibly can (that's the default). You can try changing the polling rate in Win-test from "Auto" to 500 ms, but it may not cure the problem 100%. You can also try using OmniRig instead of the K3 support built-in to Win-Test.</div>
<div><br></div><div>Make sure the second COM port option (two COM ports talking to same radio) is set to "None" in the microHAM Router dialog, for the K3 port. There may also be an option to set the radio type to "Elecraft K3 patched" instead of "Elecraft K3" in the microHAM router. That may also help. Of course your K3 should also be running the latest firmware, and you may need to upgrade or replace your KIO3 board if it is a very old one. You can isolate the problem to the K3 or MK2R+ by temporarily bypassing the MK2R+ using a real serial port connection to the radio, instead of a virtual one (don't use a USB-to-Serial adapter for this test).</div>

Switching the W-T active radio to #1 would make it stop. Or powering the MK2R off then on would fix it. And now while I'm typing this with W-T running in the background (with the log from last year's ARRL DX CW loaded) the blinking will start and stop by itself. It happens at random times.<br>
<br>
It's not RF related - I'm typing email and it's happening.<br>
<br>
Later in the weekend I was doing the CQ 160 using Writelog and it never happened. Writelog and Win-Test were never running at the same time.<br>
<br></div>
Setup - WIndows 8 (that might have been my first mistake), Router 8.1.4, MK2R+ fw 6.1, Win-test 4.10.0, Writelog 11.90B.<br>
<br>
Radio 1 is an IC-7800, radio 2 is a K3 with P3.<div><div><br>
