[Elecraft] K2 - "INFO 80 " problem

[Phil Wheeler]

Hi, Giuliano --

Congratulations on your K2. Once you have it 
whipped into shape, you'll find it to be a fine 
radio. Plus there's hardly anything in it you 
cannot work on and fix yourself if you build kits 
like the K1.

One of the K2 manual appendices is 
"Troubleshooting". You should give that a look.

Before you do any updates contact the previous 
owner and see if he can provide a list of any 
updates which may have already been done. I have 
#380 and back then the K2 was still a "work in 
progress" with most of us doing updates 
incrementally as they were posted on the Elecraft 
email reflector. For example, my K2 was something 
of a continual project from July 1999 until June 
2003, and I made *most* of the changes identified 
during that period. Then I was away from my 
obsessive focus on ham radio for close to ten 
years. When I started using my K2/100 again I 
found that I had made most of the changes, but 
there were some left to do -- and some I didn't 
need or want to do. I made one of those changes I 
wanted earlier this month. Your seller of the K2 
may have made most of the changes already, or some 
of them or none of them.

If you've not been there, go to this page 
http://www.elecraft.com/K2_Manual_Download_Page.htm#K2 
and in particular download this file 
http://www.elecraft.com/manual/k2a2binstr.pdf  It 
provides a list of the major changes in the basic 
(10 Watt) K2 and options.  See if you can 
determine which have been done -- by asking the 
original owner or inspection.

You will probably want to update to the latest 
firmware, unless that's already been done. You can 
determine several firmware versions by using menu 
options from the front panel; others will require 
disassembly and looking at the label on the chip.

If you have the KPA100 there are other mods and 
updates which can be done (there is an update kit 
and a mod kit for the KPA100).

Have fun with your K2. I have the K3/P3 combo and 
find that the K2/100 still holds its own in that 
company.
