    Well things have changed and now I’m moving into the house and that will require the use of coax instead of OWL.
    So now I’ve got to mod the Johnson KW matchbox on the coax side to allow for 160m.
    Should I come off the unused C2 side and tie in the 220pf 15k cap to the center pin of the coax output thru a toggle switch?

    Looking at it I could come off the 80m position thru the caps then the toggle switch and to ground. That might also work.

    Despite the photo he doesn't really advocate the crappy brown stuff.

    One reason there is no 160, Is because there is not enough room in the box, Without screwing up the power ratting.

    He has a specially made tuner that goes to 11.
