Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

Open the matching box at the base of the R9 and look around the toroids. 
My R8 (same box) had an arc when using high power where the wire was 
attached to one of the toroids. I stuck a piece of polystyrene between 
the wire and the toroid to fix it. You might have to unsolder the board 
from its connections to get it out of the box in order to see and fix this.


In my case it only occurred on 40m so it could be the same problem.

Hi to the group.

I promised to let you folks know what I came up with on my friends
KX3, KXPA100, and the R9 vertical.

He got the KX3, KXPA100, and KPA500 back from Elecraft all repaired.

I put the station together and this time set all 120 frequency-SWR
memories at the 20 watt level. They all set up OK and at that point
we went to lunch feeling good that all the problems were gone.

We came back and started using the KPA500 on various frequencies. Any
frequency we tried from 20 meters to 6 meters worked just fine at the
500 watt level.

On 40 meters any power over 400 watts would give a fault on every
piece of equipment (KAT500, KPA500, KXPA100 and an ANT ERR on the
KX3.

On 80 meters the faults would come on at anything over 300 watts.

I felt the faults were quite violent so that more than likely
explains how all three pieces of equipment got destroyed.

I studied the R9 which I put together last fall. On 17 meters through
6 meters there are stubs for each band and no loading coils involved.
On 20 meters there is a trap so again no loading coils. On 40 meters
there is a trap and a loading coil and on 80 meters there is another
trap and loading coil.

I noticed on 40 and 80 I could get them to tune to low SWR with the
KAT500 but if I started sending my call the KPA500 would start
showing more power and soon go into the violent fault.

Years ago I had a hustler vertical that would change the matched
frequency as the coil heated up and I think this R9 is doing the same
thing. Our solution is to run no more than 400 watts on 40 meters and
no more than 300 watts on 80 meters.

The specs for the R9 say it can handle 1500 watts and I suspect it
can on the higher bands but at least this antenna can not on 40 or 80
meters.

I came home and tried my camping KX3 and KXPA100 with my KAT500 and
Hy-Gain HY-Tower vertical and it seems to work well in any of the
memory position which I earlier set with my K3S and KPA500 so I feel
we have isolated the problem to the R9 my friend is using.

If anyone is able to use an R9 at higher power on 80 or 40 please get
back to me and let me know how you are doing it.

To everyone else thank you for the band width and suggestions.

I consider this closed.

Thank you to the three people that responded to this so far but each of you
accused me of having my friend run three tuners in a row. The KX3 turns it's
tuner off when it senses the KXPA100 is connected and turned on. There is a
setting in the MENU to turn off the tuner in the KXPA100 which we did and
have to keep watching as the equipment keeps wanting to turn it back on. The
problem we are having is tuning the KAT500. Hi SWRs are sent back to the
KXPA100 and it trips out. I was hoping there is someone out there that is
making this work. I have a K3S myself and a KAT500 and they work perfectly
together at 25 watts for tuning than the full 500 watts after it is tuned.
My friend does not have a K3S so we need to make the KX3 and KXPA100 work.

The KPA500 is not in the circuit at this time.
We try to tune the KPA500 using the station set for 20 watts and a hand

The KXPA100 often kicks out. The SWR of the KAT500 changes quite a bit
over a tuning cycle and I think that is what is causing the trouble.


Is anyone else using this combination of equipment and can give us some
guide lines on setting up each piece of equipment and a procedure to tune up
the KAT500 without hurting the KXPA100?


Thanks to anyone that can help as this has turned into an expensive
problem that has destroyed three pieces of equipment.

2017-01-26 Thread Bill Johnson 
I would suggest using a few watts out on the KX3 to start and add the 3db pad 
using the rear switch.  This will give you simpler adjustment range and hold 
the output of the KXPA100 down.

Hi The kx3 or kx2 and kxpa100 will work just like a k3 and a kpa500. Make sure 
the kxpa100 is enabled in the kx3. Make sure the tuner is bypassed in both the 
kx3 and kxpa100, also make sure the power is lower than 30w out. Then you need 
the kat500 which will tune the antenna. In this combo, the kpa500 must be set

If you are using TUNE (and not ATU TUNE), then there is no need for a macro.  
Just go into the menu and set the KX3 TUN PWR entry as desired.

The ATU TUNE works with the KX3 alone or the KX3/KXPA100/KXAT100, but I don't

know commands to turn the KX3 tuner off and the PA on in a macro please let me 
know and I will put it on one of his two PF keys.

Thanks for the help and I will let you know later how we come out.

Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

2017-01-25 Thread Kenneth Christiansen 
Hi again to the group

Jim and Fred both recommended lower power below 10 watts so the KXPA100 does 
not kick in. I tried it with my K3S when I got home from teaching the radio 
class and that does look as though it will work well. I hope to get over to his 
place this week end and get everything working. 

I no longer have enough equipment to look for spurious frequencies but most of 
the time his KXPA100 would complete and the KAT500 would show very low SWR on 
the power meter I had along. The SWR on both my meter and the SWR line of the 
K3S display jump all over the place while the KAT500 relays are operating so I 
consider that normal.

I am think of making a macro to turn the power down for tuning and if anyone 
know commands to turn the KX3 tuner off and the PA on in a macro please let me 
know and I will put it on one of his two PF keys.

Thanks for the help and I will let you know later how we come out.

Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

2017-01-25 Thread Bill Johnson 
I have this setup.  It works well.  I would suggest a menu change to 5 watt
tuning with the KX3.  Do not tune everything at once.  Big error.  Do you
have a tuner in the KXPA100?  If so set on "Man" then tune the KX3 into the
KAT500.  This will stop what you are seeing.  Too many tuners going at once
will cause what you are seeing.  If that doesn't work, turn off the KX3
tuner and use only the Kat500.  Once tuned the rest should work.

Thank you to the three people that responded to this so far but each of you
accused me of having my friend run three tuners in a row. The KX3 turns it's
tuner off when it senses the KXPA100 is connected and turned on. There is a
setting in the MENU to turn off the tuner in the KXPA100 which we did and
have to keep watching as the equipment keeps wanting to turn it back on. The
problem we are having is tuning the KAT500. Hi SWRs are sent back to the
KXPA100 and it trips out. I was hoping there is someone out there that is
making this work. I have a K3S myself and a KAT500 and they work perfectly
together at 25 watts for tuning than the full 500 watts after it is tuned.
My friend does not have a K3S so we need to make the KX3 and KXPA100 work.

Thank you

Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

2017-01-25 Thread Nr4c 
Sorry. But my solution to this problem was to use my K3S to teach my KAT500 all 
about my antenna first.  Now when I hook up the KX3 I don't have to tune the 
KAT500. It already knows the antenna. 


What do you see with a dummy load on KXAT100 with both ATUs By-Passed?  If not 
near 1:1, then start here and find out why. Once this checks, move dummy load 
to KAT500 output. Should also be 1:1 or nearly so.

Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

2017-01-25 Thread Cady, Fred 
Although the KAT500 would like 20 watts to get a good tune it should be able to 
tune down to 10 watts (from an email long ago from Elecraft).  Maybe you can 
try turning the KXPA100 off and setting the KX3 to 10-15 watts (depending on 
the band) and then tune the KAT500.


Cheers,

[Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

2017-01-25 Thread Kenneth Christiansen 
Hi to the group

I have a friend with the following equipment.
KX3 with built in tuner.
KXPA100 with built in tuner.
KPA500
KAT500
50 ft of LMR400 coax
R9 vertical.
The KPA500 is not in the circuit at this time.
We try to tune the KPA500 using the station set for 20 watts and a hand key.
The KXPA100 often kicks out. The SWR of the KAT500 changes quite a bit over a 
tuning cycle and I think that is what is causing the trouble.

Is anyone else using this combination of equipment and can give us some guide 
lines on setting up each piece of equipment and a procedure to tune up the 
KAT500 without hurting the KXPA100?

Thanks to anyone that can help as this has turned into an expensive problem 
that has destroyed three pieces of equipment.
