So here is one that has me stumped...

Out of the box, fired 7729 up…set the configuration to the quick start (which means all I did was select the external spkr set to 1). running thru a LDG AT600 pro auto tuner…and an AL-811…

All ran fine, great report across the bands…called Dave at Elecraft for some help on setting the Sql to the RF collar…great accessibility and customer service….

Came back from dinner….high SWR (ant is a Cobra Senior)

Nothing else changed…but I get untransmittable SWR off of both dipoles….really high….I tried the following:

1.) Checked against both antenna's…both way high
2.) Switched Baluns….same result
3.) Switched Ant on the LDG…no joy
4.) Tried all Bands with the Tune press against both Ant…no joy
5.) When I flip on the Amp…running 35 watts…the SWR's on the LDG show pinned…on the K3 display show @ 1.2…
6.) Receive works great
7.) Replaced the coax from the K3 to the Amp…
8.) Cut and restripped the ladder line

Receive is fine….cannot transmit since the simple allocation of the RF collar to the SQL function…

What did I miss?

Thanks in advance,

George

Re: So here is one that has me stumped...

George,

What happens when you transmit into a dummy load?
What happens if you connect the K3 directly to the tuner (remove the amp
from the path of coax)?

If my understanding of your setup is correct, the K3 will indicate the
SWR it sees into the input of the amp.
OTOH, the amp sees the SWR at the input to the tuner.

It sounds like you may have a problem with the tuner or the amp or the
coax between the amp and tuner.
You could also have an RF feedback problem that is causing your SWR
readings to be crazy.
Some work with an antenna analyzer may be helpful.

73,

KAT500/KPA500 with Icom 7100

In reply to this post by George Pontiakos

I brought my KAT500/KPA500 setup to my winter home after getting it put
together and working with my K3 at my shore residence. Now I'm trying to get
it working with my Icom 7100. After setting up the Elecraft pair, only menu
item I see to set is in the KPA500, RADIO, set to ANALOG. I'm having two
problems.
1. I'm not getting PTT to activate. I checked the AH-4 interface cable and
it has the correct pinout. If I ground the center pin of the RCA PTT cable
the AMP keys as expected. The problem is the 7100 isn't grounding pin one.
Does anyone know if there a config command in the 7100 to activate this? I
can't find anything. When you key up the 7100 the pin stays open and not to
ground as I think it should be doing.
2. I'm not getting any band switching with this setup. If I click on a spot
with DXLab I would expect the Elecraft pair to follow the 7100, I'm thinking
if problem 1 is fixed problem 2 will also be ?

All other AH-4 functions seem to be working ok. The cable powers the KAT500,
and If I hit the tune button on the 7100 the KAT500 obeys.

Coolaid drinkers, yes I know if I replace the 7100 with another K3 my
troubles will be over :-)

Re: KAT500/KPA500 with Icom 7100

The 4-wire AH4 connection doesn't PTT key the amp. It has 12v, ground, Start, which is a signal from the Icom to the tuner that is asserted when you press the Icom tune button, and ah4 key, which is asserted by the tuner when it needs a tune level signal from the Icom. The amp needs a separate PTT key line from the Icom RCA connector to the kat500, and another RCA cable from kat500 to amp. The AH4 Key line is distinct from exciter to amp PTT and although both have key in their names, they have different purposes.

One of our diagrams in the owners manual may have omitted the RCA keying cables. A manual revision is in the works.

Re: So here is one that has me stumped...

In reply to this post by Don Wilhelm-4

Thank you for the responses and suggestions:

1.) Ran the ant coax thru the balun directly to the K3- SWR 4.2/1
2.) Ran the ant coax thru the LDG 600 Pro bypassing the amp- high SWR
3.) When I hit the "tune" function on the LDG, I am getting from the tuner a message "ERR_NO_RF_" blink once warning

The only thing I can think of the LDG has an internal issue, everything else seems correct…I had the exact same set up on my prior rig, same coax etc….worked like a charm…I am beginning to think it is the tuner…

Any other thoughts….I cannot believe I set a config by accident internal within the K3 to cause this issue…

My very best to all,

George

Re: So here is one that has me stumped...

The one piece left unchecked, (in my mind and I may have missed something here) is the coax between the KX3 and the tuner.It sure wouldn't be the first time I got caught with a short piece of coax that failed at the exact "right" time... can you spell MURPHY???;-)

Re: So here is one that has me stumped...

Thanks Dale….I did change the coax out of the K3 to the amp…then thru the other troubleshooting configurations…The tuner just grinds away pinned and then stays that way...

Re: So here is one that has me stumped...

Just so I understand, the tuner still acts like it doesn't "see" the antenna? or it acts like it doesn't "see" any rf?

Re: So here is one that has me stumped...

Well that is a good question….when keyed…the tuner obviously sees the rf because it starts the calibration process and shows the wattage I am pushing….during the entire process the SWR led's show all red, the box makes the normal cal noises and the stops showing all red high swr…

So I believe it sees the ant and I believe it sees the rf…

It also worked fine initially start-up ran and calibrated to 1.2/1 with the k3 alone and with the amp engaged…

Something changed….I do not think I put a mis configuration value in the set up when I was learning the config menus (but if there is a setting that could cause this condition, then perhaps I did), short of that…I am coming slowly to the conclusion that the tuner developed a problem….

Re: So here is one that has me stumped...

In reply to this post by George Pontiakos

At times like this, it is nice to have a manual tuner that you can
substitute for the auto-tuner.
Are you certain there is no problem with the antenna itself, such that
the tuner cannot resolve the SWR?

One more thing, and it's just being "Murphy proofed"... is the tuner selected to the correct antenna port?

Re: So here is one that has me stumped...

In reply to this post by George Pontiakos

Hi Dale
I ran into a similar problem a year ago with a friends LDG tuner. He moved to a nursing home and other people put up the station and antenna in the attic. I found they cut the coax and just pushed the two ends together. We fixed that and the LDG tuner would not make a match but did try. My k2 tuner worked just fine. We found his rig was connected to the antenna jack on the LDG and the antenna was connected to the IN jack. I know this does not sound reasonable but if it happened once it'd could have happened again.

George, ON the off chance.... what was the weather like when you left it for dinner/during dinner... and was the antenna disconnected during dinner?

Have a great day,

Re: So here is one that has me stumped...

Hi from Ken
Could you have the coax from the balun and the coax from the rig reversed the same as my friend. If that is not the case try to get another rig and see if it can cause the tuner to tune. If neither rig causes it to tune than the tuner needs repaired. If the other rig causes the tuner to tune than look for a spurious output from your rig. I had this happen 40 years ago with a friends DSB-100 rig. It had such poor second harmonic suppression that a selective manual tuner showed lots of SWR because the second harmonic was reflected back and looked like SWR.

I hope these ideas might help.

I have a problem of my own that I might submit to the group later this week.

Re: So here is one that has me stumped...

In reply to this post by daleputnam

SOLVED!! It was a bad LDG tuner….3 years old…AT 600 Pro…Thank you all, Especially Dale, Don and ken for their efforts to walk me thru the troubleshooting process…

My very best,

George
