Re: K2 Modifications

[zl1aih-2]

Hi Scott,
I have built two K2s, #767 and #3725.
The only problems I experienced were my
own fault.
They were very quickly solved on this
reflector by very experienced folk like Don
W3FPR, Tom N0SS and many others who
contribute to this list.

I'm the only one (so far) that turned TWO
pages of the manual over at once, thus
missing some very important steps. <G>

The K2 has evolved since #767 but most
importantly both of my transceivers are
right up there with latest serial numbers, in
that I can update via the Elecraft list.  
They have the KI02 interface, 160m
separate Rx antenna options, KAF2 audio
filters and the N0SS amp keying circuit.

My shack is presently the base for the
ZM1A CW serious contest station.   We
have two suites of antennas for 80, 40,
20, 15 and 10 metres (quads and
verticals) located 300' apart.

Of a selection of FT-1000xxx (with all the
latest filters), Icom 7xxx, etc. transceivers,
only the IC-780 and K2 ( plus amps)
demonstrate no interstation interference at
the 500w level.  

>From the two most experienced CW
contest ops in our group (ZL3CW and
ZL1GO), the only complaint has been that
"the K2 moves when you push the
buttons".   Since then, I have secured the
bail to the bench.<G>

Scott, you can build your K2 with
confidence knowing that you have support
from this reflector no matter what
problems you might encounter.
You will have a transceiver that is right up
there with the best.

73, Ken ZL1AIH (ZM1A team in CW
contests)
