[Elecraft] Mic Settings

[Bob McGraw - K4TAX]

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.
