[Elecraft] K2 Antenna Questions

[Don Wilhelm]

Steve,

If you have other non-resonant antennas, the easiest way to handle the 
resonant antennas is to simply connect those antennas to the ANT1/ANT2 
jacks, and do a TUNE into those antennas then operate.

You can instead change the ATU menu parameter to either CAL P or CAL S 
and the L/C elements in the tuner will be bypassed.
Note that the Pout parameter retains the last used L/C combination, so 
that is not a bypass situation.

You will not (and should not) use the BNC connector on the K2 lower 
panel next to the key jack when the KAT2 is installed because you will 
not have control over the output power (power will go to maximum and can 
destroy the PA transistors).  Put a cap over that BNC jack.

Please refrain from calling that DE-9 connector on the back of the K2 a 
"serial connector" - it is NOT.
Yes, it contains 3 wires that are compatable with RS-232, but it also 
contains internal K2 signals to connect external Elecraft hardware such 
as the KAT100, KRC2 and XV series transverters.
To connect with a computer, you must use a special cable.  If you did 
not receive that special cable to the computer with your K2, you can 
build it (you cannot buy it) from that shown in the KIO2 manual.

I have a couple antennas that I do not want to use tuner with, and was wondering which jack to use and then how to select it.
