K2 - "INFO 80 " problem

I bought a K2 SN 670 to complete my collection Elecraft.
I now have K1, K2 and K3 + P3.
The K2 serial number is very low and I think some changes are essential
and others less so. Can anyone tell me what mods are the really important?
I also have a problem that occurs very frequently: when I change band
+/-, very often comes out "INFO 080". What can I do?
Thanks for the help

Re: K2 - "INFO 80 " problem

hello juliano,

I'll put the single "080 info" Book of troubleshooting, if it can help you

If you saw the message INFO 080, the
I/O controller (IOC, RF-U1) or other auxBus
device did not respond to messages from the
main processor (MCU). Turn power OFF and
back ON; if you hear some relays switching
on power-up, the IOC may be OK, and the
problem is likely to be with the AuxBus
(081)
 If you do not hear any relays switching on
power-up, your IOC (RF-U1) may be
defective. Inspect U1 carefully to see if you
have installed it backwards or if any pins are
bent.
 Pull U1 out, check its pins, then re-install it,
making sure all pins make good contact with
the IC socket. Check the 4-MHz oscillator
(075).
 Remove the bottom cover and verify that all
pins of U1’s socket are soldered, as well as
those of the 6V regulator (RF-U2), and U1’s
4 MHz oscillator (RF-Z5).
 With power ON, check all voltages
associated with U1. You should see 6V at
pins 1 and 20 at all times, even when the IOC
is sleeping (not being accessed by the MCU).

Go to the Elecraft website and download the K2 A to B instructions. That
contains a list of related mods.
You may want to also download the instructions for those mods as well.
Review those instructions against your physical K2 to see if they have
been installed.

I would also suggest changing the IF crystals on both the RF board and
the KSB2 (if installed). If the crystals installed have a "-S" suffix,
they are the new type, but any other suffix is the older type. The new
crystals will improve your filter passband shape.

The INFO 080 says there has been a failure of AUXBUS communications
between the main MCU and one of the other firmware ICs in the K2 system
(that includes the IOC on the RF Board). Since it happens when you
change bands, it is most likely the IOC communications. The first step
is to re-seat the MCU on the control board and the IOC to clean any
oxidation from the socket and the pins. If you have the KPA100 option
installed, it could also be the KPA100 communication - re-seat its
firmware IC too.
If it persists, begin removing the installed options to see when it
disappears.
That problem could also be caused by a bad solder connection. If it is
intermittent, it may take some time and trial and error to track it down.

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.

Re: K2 - "INFO 80 " problem

Thanks for everyone's help.
I cleaned the contacts on the microprocessor of the Control Board and RF
Board and now the message seems to have disappeared
( INFO 80).
I checked the firmware version that is 1.04A (main) and 1:02 on I / O.
I think it is useful to update the firmware but can not find how to
order the two microprocessors. How do I get them?
Thanks again

Re: K2 - "INFO 80 " problem

Giuliano,

From the Elecraft website www.elecraft.com, order K2FWMCIO - see the
Order page and then Spare Parts, and then select K2 on the page which opens.
Be aware that you must have the updated wiring on the Control Board for
the sidetone source.
If you have the KPA100 or the KIO2 installed, that change has already
been made. If it is not installed, refer to the KIO2 or KPA100 manual
(which you can download) and you will see the changes to the Control
Board in the installation section.
