Key-Out of the K3

Dave, G4AON
Mike

It's not currently adjustable in version 1.66 MCU firmware, as far as I
know it's on the "to do" list.

73 Dave, G4AON
-----------------------
Eric knows this and has built an adjustable delay capability into the radio,
all that is needed is how to program the delay.

This adjustment is not yet coded into the firmware but is on the list to be done.

Why my Wife won't let me buy a K3

Robert-223
I told my Wife that I was thinking of buying a K3.

She said no and her reason!

"You already have a K3.  You have a K1 and a K2"
"Therefore you have a K3.  K1+K2"

She informed me that this was the new math :O)

I had to share this.
Bless my Wife's heart.

But if you buy a KX1, you will then be back to 2! (ex-1... ;-)

That should open up room for a K3, right?

LOL - I'm glad I only have a K1 so far!  K3 should be on the way in May.

Tell her you need a K6. (I'm still holding off on the K5.) :)

Not yet.  There will be a menu item for an adjustable delay within certain limits, but I cannot say exactly
when it will be available.
