[Elecraft] WTB KX3

[Jim Rodenkirch]

Let's open up requirements statements like the below some for discussion:

1) It's correct to state "The options you select for the KX3 will mostly be
determined by your 
operating aspirations and your antenna system."

However...........

2) I will posit it's not necessarily a 100% "for sure/correct" suggestion to
opine, "If you do not have resonant antennas for all bands, then you will
want the KXAT3."

'cuz, it really depends.................the below scenarios should provide
examples that support my above posit:

Scenario #1: If you have installed a "non-resonant antenna" of sufficient
length to operate at the lowest frequency of interest, with a properly fed
auto-tuner at the base (a vertical) via a short (< 10') run of low loss coax
OR at the center feed point (a dipole, including OCF) via open wire feed
line to the auto-tuner located outside with coax between the auto-tuner
input back to the shack AND you intend to never take that $1300.00 + radio
out of your shack, an internal ATU is worthless.

Scenario #2: You erect a vertical or dipole of sufficient height/length
("sufficient" means tall enuff to be nearly a 1/4 wavelength at the lowest
intended frequency of operation), can employ open wire feed line all the way
back to the shack where an efficient auto-tuner that costs less than the KX3
resides, understand how to wind a matching transformer (do not infer I am
including a balun or un-un in the discussion of a matching xfmr), will
employ same xfmr to transform the 600 ohms of the open wire line to near 50
ohms AND intend to never take that $1300.00+ rig out of the shack, you don't
need to purchase Elecraft's internal ATU.
