Put Amidon T200 red balun by left hand

Put roll of rad-shark 20 ga clear-vinyl spkr wire by left hand

Wind speaker cord all around toroid neatly (both hands)

solder "copper" conducter to tinned condutcter where winding ends & begins

connect antenna to open ends of wdg.

connect TCS to one open end & center soldered junction making sure chassis
connected to same 'wdg. end' as coax shield.

Fold both hands in prayer

Tune up

This makes a 2:1 turns ratio (4:1 Z ratio) step down.

At 80m, Z for seriesed toroid wdg.s 'way higher than 50 ohms so return-loss
instrumentation, etc. plain unneeded.  (checked w. URM25 w. 1k seriesed
w. wdg.s & B&K RFvm reading)
