New Purchase Sanity Check

[Michael Greb]

Ready to pull the trigger on a KX3 + PX3 + KXPA100.

I plan on the internal tuner for the KXPA100 but I'd like the option of
working without it.  If the KX3 internal tuner is installed but the KXPA100
with internal ATU is connected will the KX3 correctly bypass its internal
tuner causing the tuner functions to operate on the KXPA100's tuner?

Thanks

When the KXPA100 is on and  power over 10-12 watts  the internal tuner in the KX3 is bypassed and the tuner in the amp is operational.   If the

Mike,

Yes, that is the way it works - and it is automatic.

Don,

OK.  Makes me curious what is happening with my KX3+KXPA-100 (without KAT100).

My KXPA-100 reaches 100w with 3.9w*drive from the KX3.  If, when you
state 10-12w, you mean output of the KXPA-100, I'm not sure I can get
it down that low.  The KXPA-100 LED PWR meter reads 25w with only
0.1w drive from the KX3.

I do have the KX3 ATU which is normally run when operating.  Input
SWR looks like 1.1 into the KXPA-100 (haven't bypassed the ATU to see
if this is normal SWR).

*Note requires 8w drive on 6m for 80w output.  Exceeding 8w will
activate auto-attenuator in the KXPA-100.

Ed,

I did not state 10-12w.
I think your KX3 and KXPA100 is working OK.
The KXPA100 was designed to be driven to full output with up to 5 watts
of drive (it works with the Yaesu FT-817).
The drive power specified is 3.5 to 7 watts, and you fall right in that
range except for 6 meters.
