Then I am ok with my two Force 12 antennas and the
F12 bead B-1 baluns. I have the C4 with separate
lines and baluns on the boom: one for the EF140S
40 meter dipole, the other for the C3. Have
run QRO a lot, no problems as described above
have occurred in several months since the new
Henry Ultra linear has come to live here on Kauai!
Worked R1MVA on the first call! Only 5 degrees
to the west of the N pole form here, and a loooong
ways as well.
