[Elecraft] Problem Tuning K3

[JR]

Jim Brown says --

	I suspect you don't understand the physics of
	the problem. OCF antennas are a yesterday's approach
	to multiband antennas. They are a recipe for RX noise
	and RF in the shack.

NOT SO, DICK TRACY !

While YOUR OCF dipole may have problems if poorly deployed and implemented.  It is a PLAIN FACT based on thousands of real world examples, OCF Dipoles DO WORK WELL.  Mine works very well with NO CMC or other problems.  A few years ago, I gave some minor assistance to a notorious German operator, DJ0IP, as he collected a wealth of empirical data on CMC and OCF dipoles, carefully testing multiple examples before designing a commercial product that has been well received by the QRP crowd, receiving positive reviews in the RSGB and ARRL magazines.  He received even more assistance from W8JI and G4TXQ and others,focusing their attention on how to avoid common mode current (CMC),  discussing where to offset the feed point, and how to construct a proper combination balun and choke.  My OCF Dipole is split 25% /75% split and Rick selected a very different feed point, and all is good.

CMC is NOT a necessary evil as Mr. Brown suggests. It CAN be curtailed with "proper care and feeding" (pun intended) and the proof flies over my shack, and over hundreds of other shacks, including DJ0IP's station, around the globe.

Pedantic dogma be hanged !!  I base my claim on 1) real world results,   2) TONS of empirical research by others,  and 3) input from my local Elmer/guru who designed RF gear for NASA and the AIR FORCE and commercial interests.  Mr. B's theory is out of step with the real world.    (smiling as he typed that, Pardner...)  :-)  -K8JHR-
