Re: [Elecraft] K2 Build: Options Advice

2018-05-26 Thread Neil Zampella 
I just finished my K2 build, with all the options and Agree with Peter, 
there if you buy the options now, the K2 manual will point out just when 
you should install the various plugs and other components during the 
main K2 build.


My advice, all the K2 manuals are online as PDF at the Elecraft 
website.  I took a look at them prior to ordering my K2, and saw where 
the various options are referenced.  That made my mind up fairly easily.


For instance, at the end of the Front Panel assembly of the K2, it has a 
section for 'uninstalled components'.  It lists those component areas 
that should not have anything  installed, however, it then tells you 
that these areas are for the KSB2 SSB adapter, and if you have it, you 
should go to that option kit and install these components now, according 
to the KSB2 kit instructions.    I do advise that you do the inventory 
of the KSB2 so you know all the parts are there, get the ones you need 
to install on the Front Board, and set the rest aside.


Trust me, getting the ones you listed with the K2 will save you a lot of 
time, and desoldering later.

There used to be a, third party, product, called UnPCBs, which provide a

dropped to a level where it wasn't worth another production run for the
PCBs for this.

[Elecraft] K2 Build: Options Advice

2018-05-25 Thread Dauer, Edward 
I see no disadvantage.  

I have built three, each of which has all of options you are considering.  As 
David says there are some parts that need to be unsoldered, and a couple where 
the through-holes need to be cleaned up for inserting something else.  
Nonetheless, when I built mine even though I ordered the options at the same 
time as the base kit, I finished the base kit completely first, then went back 
in to add the options.  Two reasons -- first, if there were to be a problem 
somewhere I wanted to be able to analyze it in the least complicated way.  So, 
K2 first, test, then each option and its test.  Second -- it's a kit.  That's 
part of the fun.

Ted, KN1CBR

The disadvantage is that you will need to unsolder some components.  In 
most cases, I think you can destroy the through holes, but there is at 
least one case where you have to insert a new value in the old hole.

There used to be a, third party, product, called UnPCBs, which provide a 
minimal dummy version of most of the modules, but the sales of the K2 
dropped to a level where it wasn't worth another production run for the

Thanks all for the advice. I'm going to build the base K2 first. I'll just have 
to use resonant antennas or the kxpa100 w/internal tuner until the KAT2 has 
been added.

There is no real disadvantage, other than the fact that the base K2 must 
work into a 50 ohm load for proper power control and proper PA loading.


For that reason, I would suggest the KAT2 be the first of those options 
that you add.

None at all. Add what you want at any time after the initial build. 
You'll have a better idea what you actually want after playing with the 
base K2 for awhile.
