High SWR into Dummy load

Hi, I just finished putting together my 2nd K3, downloading all the
firmware, etc., and find that while everything seems to work fine, my SWR is
astronomical -- like 15 to 1 after the antenna tuner has looked for a good
match, and that's into a 50 ohm Elecraft dummy load.

This is a K3-10, with KAT3, KDVR3, KXV3A, KIO3, KUSB.

Before I tear it apart again, I'm just wondering if there's something
obvious that I'm overlooking.

Thanks in advance for any suggestions.

73, Dave

Wrong ANT port?

Make sure you have the ATU and coax to ANT1, 2 hooked up right. You
can be a good view of this from the outside.

Dave,

Check the coax between the K3 and the dummy load. Best check is to
connect an antenna analyzer to the end connnected to the K3 with the
dummy load on the other end.

Do you have the coax connected to the right antenna port?
