What does this mean, exactly? If the K1 or K2 is presented with high SWR, will the radio shut down or shut off or unkey or something? -------------------------------------- I just had that experience with my K2/100 last night, Stephanie. I was chatting with a station on 80 meter CW, running 100 watts, when I noticed the power output go to zero. I still had sidetone as I keyed, just no RF output. Now, in six years of operation with K2 S/N1289, I've never seen a burble. Power was still on, but output was zero. I applied "immediate action". In the Army that means kick the [EMAIL PROTECTED] out of your weapon when it jams in the middle of battle. On the K2 I was a little less violent: I cycled the power off then on again. Keyed the rig and RF output was back and normal. Hmmmm... "red flag".... But it keyed FB and I apologized for the break to the other guy and continued with the QSO. A minute or two later it happened again. Cycled power again. Now I'm wondering if the Astron supply is dying. A minute or so later it happened again. This time I caught a glimpse of "HI REFL..." on the LCD and notice my external SWR meter jump too. So I signed and investigated. I had been swapping cables around and the antenna cable to my external ATU was loose and making intermittent connection. When it would break connection, the SWR went "through the roof" at full power and the 100 watt amp shut down automatically without damage. Tightening the connector fixed the problem.
