[Milsurplus] More TCS questions

} With both a 100 pf cap and a 1 to 4 step up transformer, I get 40 watts 
} with the coupling control at about half scale.  This tells me the command 
} set was not designed to match a resistive component as high as 50 ohms.

It doesn't tell me as much as it tells u.  I dunno what C shud be to 
cancel the command set's link Xl.  If u put a variable C in series w. 
load & set it for max out into 50 ohms for a given coupling, you've got the C.

I'm w. u that the command set was intended for "HF shorties" & R=50 was
probably never considered.  But for the TCS, there's plenty of "link left"
~3580 kcs w. that variable series C.

Command sets.  Both SCR274N & SCR183 (note Bugle Boy Stinson).  '183
antenna write-up really good BTW.

HOLY  COW!!

Forgot to say why tuning out link's Xl so important.  If non-zero, trans-
mission line current and voltage peaks non-coincident.  IE, phase shifted and,
since you can't dissipate power in a capacitor nor push a rope, full
out ain't there.

Zero reactance is condition of unity power factor if you work for TVA.

I runs a TCS w. a SB200 as does WA4OID.  We both treat amp match same way
with a in-line variable C.  Capozzi calls his amp an "active tuner."

12W AM into an SB200 gives ~80W carrier out / 300W pep.  'bout like a 
DX100.
