K2

[DL1XAS]

Hello, I think have a programming problem with my K2. Only one band(40m) I could not change the VFO knob on the band. But if i change the knob slowly I see that we change two frequencies on this band. Sorry I don't know which change I did, how can I change this programming in the menue? thank you for your help 73 de andy dl1xas

Andy,

Is this a K2 with the new VFO encoder?  In other words, does the encoder
have a board attached to it?
If so, your problem is that the encoder board is touching the leads of
the Control Board behind it.  Flush trim the encoder board and the area
of the Control Board behind it.  I mean really *flush* trimming the
leads, there is no extra space.
You might even put some insulating material (fiche paper) between the
encoder and control board.

The only menu entry dealing with 40 meter VFO operation is the secondary
menu D19 entry.  That should be set to "N" if the K60XV option is *not*
installed (nor the Rework Eliminator wiring for the K60XV) - if that
option *is* installed, set D19 = Y.

If you have the older encoder and the D19 menu setting is correct and
the problem is only on 40 meters, do you have the KPA100?  If so, does
it have the speaker magnet shield?  An unshielded speaker magnet in the
KPA100 can interfere with the operation of relays K13, K14, and K15 in
the base K2.  Remove the KPA100 and see if the base K2 behaves
correctly.  You may need to upgrade the KPA100 shield with KPA100SHLDKT.

Hello Don,

I have the number K2 6345 and I have also the KPA100 and the 160m module.
I looked at the KPA100SHLDKT , I think I could integrate for the future?
I have been written all the configuration of the settings i had done before, and then i took the 456..
and all is okay now. The channel hopping may be the problem, but I couldn't resume it.

So thanks for You DON

Andy,

Your K2 should have the old encoder, and the KPA100 shield and speaker
magnet shield should be the latest.
Yes, if you set Channel Hopping on, that would create something similar
to your observations if you had set memories on 40 meters.
