JVII Output Coupling

[W7SOE]

Hi All,
    I finally have my Viking II on the air.  This after I was unable
to tune my 40m dipole until I added some length to it.  (For 75m)

I am concerned about the output coupling though.  The dipole is still
short for 75m.  When I tune up the Viking I get to ~200 mA of plate
current on the first main coupling setting.  When I tune on 40m I keep
increasing the coupling to four or five as I would expect.

I can increase the coupling one notch if I diddle with the Matchbox,
basically increasing the SWR to drop the plate current.  It seems to
me I can then increase the coupling setting on the transmitter but
maybe only to heat up my feedline.

Does it seem reasonable to hit the desired plate current on the lowest
output coupling setting?

thanks

my V2-CDC does the same thing but my screen voltage on the finals is a bit high 218 V so thinking I need decrease it.  Plate voltage 760 V after solid stating the supplies and adding a second 8 uf filter cap.

dont use ur flash box to tune your rig. set it for lowest swr and tune your tx to that. whatever it is is what ever it is as far as coupling goes, low on the low bands and upwards of 8 or 9 plus the variable on >15; 10 meters.  NEVER use the antenna tuner to do anything but reduce vswr to the lowest you can get it. then all the tuning is done with the tx.
