[Elecraft] Re: K2 Modifications

[zl1aih at ihug.co.nz]

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.

contests)
