Well again we get into conditions which typically manifest into Common
Mode Current issues. Depending on antenna, I always carry a coax jumper
with a bunch, as in 50 to 75, of Ferrite beads of #43 and #73 material.
This is always connected direct to the ANT connector on the radio. If
you are using an OCFD antena then additional CMC choke will be needed at
the feed point. Most baluns are very inadequate in this regard,
regardless of what the manufacturer says in print. OCFD are noted to
have CMC issues unless proper balun and CMC chokes are used.
See http://www.dj0ip.de/antennas/ <http://www.dj0ip.de/antennas/> for
further info on baluns, common mode chokes and OCFD antennas.
On EQ, I suggest setting TX EQ: 50 Hz @ -16 dB, 100 Hz @ -12 Db, 200 Hz
@ -6 dB with the remainder at 0 dB.

I know this subject has come up many times. I brought my new K3S to Aruba
and it's my first time using it on SSB. Before my trip I listened to myself
on another radio and thought that I had the settings figured out, but now I
have some doubts. Yesterday on 15m I received a comment that I was hard to
zero beat on SSB. Thinking it could be RFI, I switched from the small
Powerwerx power supply to an old Astron and added some ferrites to the mic.
Today I was on 10m a little and asked a couple of people how my audio was,
one said basey and one said high. I am using a Heil HC-4 element with no
equalizer settings, mic 30 compression 18. I wonder what setting other
contestors are using with this element.
