Re: [Elecraft] K3S Upgrades

[Don Wilhelm]

Geoff,

I did not see a reply on the reflector, so I am offering my opinion.

The order I would suggest is to add the KAT3 first, then the KPA3, and 
last the K144XV.
That order suggestion is based on physical space, nothing electrical.  
It is easier to install the KAT3 before the KPA3 because there is more 
"finger room".  The K144XV should be installed last because it sits atop 
everything else and you would likely want to remove it to install the KPA3.


Whether you test each one as each is installed or wait until you have 
everything in is up to you.
Testing each one as it is installed will tell you that piece is OK.  If 
you wait until all of them have been installed, in the case of trouble, 
all you can say is that the problem is with one of the options 
installed.  If you are *really* good at troubleshooting, then you will 
be successful either way, but since you felt a need to ask, I suspect 
your confidence level is not that high and you should test each after 
its installation.

Is there any preferred order to install them? Left to my own devices I

I believe that if you look at the kit assembly manual, it will reference the 
installation of these items at the appropriate point during assembly. The kit 
manual is available from Elecraft website as PDF.

Re: [Elecraft] K3S Upgrades

[Mark E. Musick]

Hi Geoff,
I have built two K3/100s and one K3S/100. All three with a KAT3/KAT3A.
Knowing how tight it is putting in the KAT3/KAT3A, I would install that
first. Then the KPA3 and the K144V last.
I have never installed a K144V, but I suspect you have to install the KPA3
before the K144V.

Mark, WB9CIF
