[Elecraft] [K3] K3: SWR meter adjustment

It's possible the K3's SWR indication is off. I'm trying to help you remove
the other possibilities for error first.

If you have a KAT3 it must be in BYPASS. If you need it to obtain the match
at the K3 the K3 SWR reading will not indicate the actual SWR on the coax,
only the SWR the K3 "sees" through the tuner. 

If you don't have a 1:1 match with the KAT3 in BYPASS, you'll need a good 50
ohm dummy load to compare meters. 

If you're still concerned, post a query to K3support at elecraft dot com.
You'll find a wealth of help from the Elecraft technical team, including the
engineers themselves.

Here are the results on three bands:
Each radio or antenna analyzer is connected to the exact same coax, there
are
no added switches or connections, the coax goes straight to the antenna.
              K3       IC-7000      Palstar Antenna analyzer
40M        1.1:1         1.5:1              1.6:1
30M         1.2:1        1.5:1              1.6:1
20M        1.1:1         1.5:1              1.4:1

Sure looks like the K3 is off to me comparedf to the other two
