Hello,
I have had a different experience with regards to the 6M performance.
I was always told for years that the 6M performance on rx was pretty poor.
After I got a K3 recently, I found
the internal preamp to be pretty good. But, I had a DEMI 6M preamp, so I

Thanks, David. I never loaded 4.57 and the current notes on the Elecraft K3

Hi all,
I just completed a KAT1 for an older K1. The tuner passes all tests but
won't tune an antenna or a dummy load. When tuning all the relays
activate but at the end I get the message r 9.9. The MCU is v1.09e. I've
very carefully gone over all solder connections looking for bridges etc.
I know that this has probably been discussed before, but just how bad is
the K3 on 6m/10m?
Hopefully, the KX3 doesn't suffer this fate as well.
It's one thing to spend another $160 on the 6m/10m preamp, but it also
requires the KXV3A at another $120.
Yes, that would also provide the ability to

bands.

What happens when you put a dummy load on it and attempt to do a TUNE -
what SWR does it report?
If it is still 9.9 or something else above 1.5, then you have a problem
with the K1 tuner - any chance you wound T1 in the direction opposite to
that shown in the manual?

Are you doing the component tests (C5 to C6 for example) into a dummy

Trying that test into an antenna just adds a lot of other unknowns into

Not only that, check the dummy load and the coax going to it - if you

I figure you are using a multiband antenna. It may be presenting a very
low or very high impedance to the KAT100 on 20 meters. The solution is
to add or subtract about 1/8 wavelength of feedline to the antenna
system. On 20 meters, that would be about 8 feet of feedline.
