[Elecraft] K1 ATT LED flicker

As I recall, the flickering is completely normal.

Usually only one or two flickers then nothing for a while (several minutes or more). Sometimes, perhaps by coincidence, when I switched on the attenuator then switched it back off, the flicker appeared to go away. This may be totally unrelated, as I said, perhaps by coincidence. I should note that when the ATT LED is lit it seems to be "emitting light" without any discernable flicker. Well, today I happened to be playing around with the display mode and when I set it to the BAT mode (ATT off) I got a continuous flicker at a rate of about 4 flickers per second. Oh, the BAT display value was 13.4V, just in case you were wondering.
