K3: Replacing Headphone Jack

[Paul Kirley-2]

Dear OM Pete N4ZR,

Instructions for removing and replacing the K3 front panel assembly are
included in the following two Elecraft documents, neither of which I was
able to find today on the Elecraft website.  Copies of each are attached
for your use, but will of course be stripped from this post before it is
sent to the reflector.

K3_Remove_Replace_DSP_Board_Rev_B.pdf
replace p35 and p30 on the k3.doc

When the Elecraft website was rearranged according to type of document
(manual, modification, part installation), the manuals for part
installation appear to have been removed from the website.  As far as I
can tell, this is the case both for the parts no longer available and
also for those still available, like the front panel gold pins p35 and
p30.

I expect that paper instructions accompany those parts still available,
just as they did when the instructions were also downloadable.

73, Paul W8TM

Hello,

 Installation document for any option that goes in the front panel has the front panel disassembly directions.  

One example is the KDVR3.  Here is a link to the manual on the K3 website: https://ftp.elecraft.com/K3S/Manuals%20Downloads/E740130%20KDVR3%20Option%20Installation%20Rev%20C.pdf <https://ftp.elecraft.com/K3S/Manuals%20Downloads/E740130%20KDVR3%20Option%20Installation%20Rev%20C.pdf>

In those instructions, look at pages 6 thru 8 on how to separate the front panel from the rest.  In the process, you will also remove the bottom front cover which you need to have off to replace the p35 and p30 jumpers.

Happy Saturday from So-Cal.

Quick question for K3 owners.

A local ham who has 2 K3 radios,wants me to take rig # 1 which has a newer
KSYNA board,and swap it with radio # 2 which has the older board.

I have done many upgrades where I remove the old board,replace it with a
newer board..do the calibrate function as per the manual,and it works
fine..super easy..

When I do it in reverse..put the older board back into a radio that has the
newer board ..do I still do the calibrate step ? or will it work fine after
the swap ?

Thanks in advance for any input,
Larry k6ro
