KX3 "TUN PWR" option ignored?

Nicklas Johnson
Just noticed that using the internal tuner, the TUN PWR option on the KX3
seems to be ignored, at least for any value less than 3W.  That is to say,
if I choose any transmit power less than 3W, the KX3 still uses 3W.

Am I doing something wrong, or is there some other option overriding this
one?  I'd much prefer to use the lowest amount of power practical when
tuning.

Saying something doesn't make it true.  Belief in something doesn't make it
real. And if you have to lie to support a position, that position is not
worth supporting.

Nick,

The ATU needs about 3 watts to find a good match, and that is the default.

If that's the case, it might be nice in a future firmware to make 3W the
lowest value for tun-pwr.  As it is today, it makes it appear as though you
could select values as low as 100mW, even though you actually can't.

Ohhhhhhhhhhh!  Thus my confusion, and I was in fact thinking the wrong
thing.

Thanks for clearing that up!!

Nick,

You should be able to adjust the (transmit) power level well below 3
watts right now, but if you do an ATU TUNE, the power used for that
should be 3 watts.

ATU TUNE and TUNE are two different things - check the manual info for
TUN PWR in the listing of menu items.  It clearly states that the ATU
TUNE uses either 2 or 3 watts.
TUNE should follow the power setting if TUN PWR is set to NOR.

73,

I think the ATU needs 3 W to work reliably.
