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 have updated via the
Elecraft list.   They both 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.
