[Elecraft] K1 ATT LED flicker

[COLIN WHITMORE]

Ok 'Crafters, here's one for you! =20

I have a K1 (s/n 942) which has the KFL1-4 (40, 30, 20, & 15), the KAT1, =
and the KNB1. There haven't been any modifications to the radio, with the=
 exception of the "blue cap" mod and any changes required for the options=
 that are installed. I am powering it with an Astron RS-4A supply.

Some time back, while operating in very low light conditions, I happened =
to notice an occasional flicker coming from the ATT LED. Usually only one=
 or two flickers then nothing for a while (several minutes or more). Some=
times, perhaps by coincidence, when I switched on the attenuator then swi=
tched it back off, the flicker appeared to go away. This may be totally u=
nrelated, 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 fl=
icker. 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.

I haven't crack it open to verify any values or anything.

So, what say you?

Cheers,
Colin

K1 #942 - flickering and causing general mischief, perhaps out of jealous=
y for the K2?
K2 #2833 - causing dust to accumulate onto it's little brother! With a sl=
y snicker, I'll wager!
