KXPA100 et Smarttuner SG230

Hello,

My configuration : KX3, KXPA100 (with KXAT100, not used in normal
operation), coax line, SG230 (Smartuner), doublet.

My question :
In way to tune the Smarttuner, I must send some RF into the Smartuner
via the coax line. Before the tuning process begins, the SWR in the coax
line to the Smartuner may be very high. In this case, the KXPA100 goes
into Fault Condition ("Err Ant") ; no RF more, the tuning process stops.

Roundabouts :
1. PA off (via menu), tuning with KX3 barefoot.
2. KXAT100 on, KXAT100 tuning, Smartuner tuning, KXAT100 off.

Doing so (1. or 2 above), I can get the Smartuner tuned, but it's a bit
cumbersome.

Any idea ?

Re: KXPA100 et Smarttuner SG230

I have exactly the same setup except that I use an SGC237. Set tune power to
5W and use the tune button on the radio. Works a treat for me.

Re: KXPA100 et Smarttuner SG230

I think that you may have misunderstood me. Set the menu item "TUN PWR" to
10W and then you can just press "TUNE" (hold XMIT) to output 10W to the SGC.
You don't need to set power to 10W - leave it at 100W or whatever you
prefer.

In reply to this post by luc Favre-2

We have beta firmware for the KXPA100, now revision 1.28, that causes the KXPA100 to be much more tolerant of SWR and reflected power encountered while tuning an external tuner. As others have suggested, set TUN PWR to a low value between 5 and 20 watts depending on the needs of your tuner, but normal Tx power can be left at 100 watts. The KXPA100 won't tolerate without faulting really high reflected power (above 50 watts) or long duration reflected power above 20 watts or so.

See the KXPA100 firmware page on our website.

Luc,

We recently improved both the KX3 and KXPA100 in situations like this. Please load the latest beta firmware releases.

Re: KXPA100 et Smarttuner SG230

Luc/Wayne,
Yes. It does work fine. I have an SGC-230 connected to one of my
antennas, also. The only suggestion that I can make is to make sure that
the tune power is above the minimum required for the '230. If the SWR is
very high before the system is tuned, the '230 doesn't quite make it all
the way if you don't start above minimum required power. The sensitivity
is primarily at the lower frequencies. Otherwise, no problems.

I'm also going to change the limit on the KX3's "TUN PWR" menu entry so you can specify QRO power levels (> 10 W) with the TUNE switch.
