[Elecraft] KAT3 in 6m

[Johnny Siu]

Perhaps, I should clarify my measurement.  The power readings were taken by LP100A on a Bird dummy load under 'BYPASS' mode.  To reiterate, in my case, I got higher RF output when connecting my 6m ant to ANT 1.



TNX & 73,

But keep in mind that the antenna tuner parameters are saved per band AND per antenna. So 
the tuner may be set slightly differently for the two antenna outputs. I suspect that if 
you set the tuner to BYPASS and checked with a dummy load they would be the same.

Also many digital wattmeters have poor resolution. Maybe the difference between 82 and 92 
watts is just one bit and the power is close to 87 watts in both cases!
