[Kenwood] SWC-3 Coupler info needed

[J. Keith Carter]

About a week ago I posted for info re problems with my SW-2000 and
SWC-3. Thanks to this group I received info that enabled me to verify
the calibration of the SW-2000 indicator unit. However the calibration
with the SWC-3 directional coupler is still not right. I have adjusted
the cal pots in the coupler, however I am at the end of the adjustment
of both pots and I cannot achieve the requirements of the cal for the
2000. (too high). Using a Bird 500 watt load there is no reflected
voltage so I must assume that the trimmer capacitor in the coupler is
correct. Does anyone have the calibration information for the couplers.
i.e. SWC-1,2,3,. Or any information that may help. Thanks in advance,
Keith, VE3JKC.
