[Elecraft] KAT100 and external watt meter question

[Glenn Maclean]

I have a question as to what is the best way to use an external watt meter?
I have a DAIWA CN-101L external watt meter. I originally had the K2100 RF
out going to RF IN on the KAT 100 and ANT1 on the KAT100 going to connector
labeled  TR  on the external watt meter and then the antenna connected to
the connector labeled ANT on the external watt meter. I was getting a good
match according to the K2100 display and the KAT100 LED's. The external watt
meter however was showing high SWR on some bands especially 30 meters. On 40
meters and 20 meters the external watt meter, KAT100 and K2100 SWR displays
all agree. On other bands the external watt meter showed very high SWR. I am
using a Carolina 40 Windom antenna by Radio works.

I re-arranged the configuration of the watt meter by connecting the RF out
from the K2100 to the TR connector on the external watt meter. Then the ANT
connector on the external watt meter goes to RF in on the KAT100. Then I
connected the antenna to the ANT1 on the KAT100. I then went through the
bands. The KAT100 re-adjusted the settings on all bands. Now the external
watt meter shows matched power out readings compared to the K2100 display.
The SWR is low on all the bands according to the external watt meter, KAT100
and K2100. Is this the best way to have an external watt meter connected?

Thanks,
