[K3, KAT3] ATU icon

[Gary Dezern]

The K3 owners manual contains the following text:

The ATU icon will flash briefly whenever new settings are automatically loaded.

I've never noticed this flashing and I'm curious why not.  The ATU is set to "auto", and I'll go to the bottom of the CW portion of the 20m band and tap "atu tune" so the antenna tunes.  No flashing, but it tunes down to 1:1.  Then I'll jump into the middle of the voice portion of the band where I've previous tuned up, but no flashing.  I'll hit "ATU TUNE" and it gets down to 1:1 again.  Then jump back to the exact frequency at the bottom of 20m, and still no flashing.  

Same thing jumping bands... The "ATU" icon never flashes.  However, it SEEMS that the ATU it switching in the proper tune...  There just isn't any real indication of that until I transmit.

Am I missing something?

Thanks

  It doesn't flash until you actually
transmit at the new freq.

I tried the same test, but TX'ing after each frequency or band change - and still no flashing.  It appears that the tuner IS pulling in new settings (as the SWR doesn't jump up), but again - no visual indication.

  It only flashes very briefly, you
gotta *not *blink, and it is possible
that there was no change in the ATU
settings at the new freq.

That worked...  3.995, tune, 3.505 and tune... and back to 3.995 with a short ID and I saw the ATU icon flash.  Strange that I don't see it when changing bands, though.  

Thanks for the advice, Sam.

Take care and 73

You have to transmit once.  Otherwise, you'd have relays clicking
constantly as you tune the band.  Works fine for me
