K3 Audio and Remote I/O Module Chokes

[Robert Dorchuck]

Good Morning All,

Just received K3 Serial 2765 yesterday afternoon.
In looking at the Audio I/O board chokes L3, L5 and L8
are still in place and not jumpered.  L7 (Mic ground choke
has been removed).

On the Remote I/O module L1 (RS232 ground return) is still in
place.

Do I still need to install the jumpers around these chokes per
the Application Note?  

Or are these changes optional?

Thanks,
Bob  W6VY

Robert, when I got to the part concerning the chokes I was told if you are
not having a problem leave as is, so I did (I did add the jumper to mic
....same with sense mod (However I did the sense mod anyway).

Bob:  Suggest that you refer this question to Elecraft Support.  Based on
the S/N they should be able to tell you if the mods have been done or not.
