KAT3 problem

When I hit the ATU TUNE button this evening the tuner sounded like it was
doing something but instead of the usual display of VSWR as it tuned there
were only two dash lines.

The problem is not band dependent.

Anyone ever seen this before and if so what was the cure?

Thanks.

Re: KAT3 problem

Barry,

I had the same thing here a few weeks ago. I found that I had no output
from my LPA board. It is now at Elecraft being serviced but I have yet
to hear the final resolution. It has only been in service for a week or so.

I used a scope and did some signal tracing and found that I had RF on
the input of the LPA board and a logical HI on the 7T line. But I had no
output from the LPA itself. I worked with support and we determined that
something was probably wrong with the board itself. I removed it and
sent it in.

I found this doing the same thing - tuning up and only had two dashes on
my display.

Hope this helps.

Re: KAT3 problem

BTW - some of the obvious things to check first would be to insure you
aren't in test mode or that the TX INH pin is not set or floating (check
in the Config menu).

Hi Dave,

Thanks for the info. It looks like mine will be heading back to the factory
also.

Have a great day.

Barry,
I just went through the same thing here. It turned out to that I had no
output from my LPA board. It is currently at Elecraft being serviced. I have
not heard from them yet as to the exact cause. It's only been in for a week
or so.
I used a scope to verify I had RF coming into the board and a logical high
on the 7T line but no output.
I found this trying to tune up as you did and saw the same two dashes on the
display.
Hope this helps.

Hey Barry,

If you are so inclined, you might try re-seating the LPA board. I did
read a couple of instances where that cleared up the problem. Although,
it did not clear mine up :-(

Either way, it you wouldn't mind, please post back your findings. I'd be
interested to see if it was the LPA or not.

Take care & 73,

Re: KAT3 problem

Hey Dave,

I'll try that and report back but I'm getting the feeling it's going to back
to the factory.

Re: KAT3 problem

Gary,

If I were you I'd call Elecraft support before sending the board. They may give
you some tests to make to determine if you have the same problem as Dave.

Re: KAT3 problem

Besides, you should *never* just send an Elecraft radio to Watsonville
for repair.
There are repair depots all over the globe.
Contact support, and if warranted, they will request an RSA number for
you. When you get the email with the RSA form, fill it out and read the
2nd page to find out where to send it.

Hi Tom,

Yes I'll talk to Gary before I send anything back to the factory. The rig
has been back before so I know the procedure. I'll call him tomorrow.

Thanks and have a great day.

Hi Don,

Yes I'm aware of that but thanks for reminding me. Having an RMA first is
definitely the proper procedure.
