Paint on Black Panels
This was conveyed to me in a mail ...
Wayne and Eric are aware of the black paint issue and they're working on it. I don't know how many panels are involved, but you might query Eric about it so you're in the queue for a better painted panel when they get them.

Flat Head Screws
This was conveyed to me in a mail ...
Yes, it seems everyone is getting exactly the most difficult to replace locally screw in the kit - those 4-40 flat heads! I'm hounding Aptos about adding spares. I see that Eric has said they're working on it.

KXV3 Isolation
With the KXV3 where very strong signals on the external antenna might cause purity problems on the transmitted signal on another antenna in some rare cases.
This involves mounting a small, postage stamp sized PC board onto the main relay of the KXV3 with the supplied double sided tape. There are 4 minor solder connections.

AGC Pumping
This will be an RF board modification to the AGC circuit that improves on a scenario that I noticed early on with my K3.
I saw the AGC pumping while receiving a CW signal using a 800hz DSP filter setting, but heard no QRM.
I found an S9 +20 db signal was about 2 khz away.
Turning on the 1.0 roofing filter made the pumping disappear with no degradation of the signal I was listening to whatsoever, but Elecraft seems to want to improve this condition for those that don't have other than the stock 2.7 filter. Something will be released shortly.
There are five SMT resistors involved and at first I was apprehensive about doing the mod for myself, but after the K2's I built I also built a SoftRock 40 and it has SMT in roughly the same scale so I decided to perform it. Two of the SMT resistors are simply removed and shorted, two are removed and replaced with a different value SMT resistor, one is removed and replaced with an LED package of the same size as the SMT resistor it replaces, and one small resistor is connected to two different SMT resistors that have a comfortable separation. If you have a couple of low watt soldering irons and a steady hand, some magnification and good light, it's a good project. But sneeze and you could lose a part forever. No joke.
After some investigation (GOOGLE), I found that there are some "Hot Air" tools for this purpose, but they are -expensive- and unnecessary for this procedure. Onr thing that is necessary is a small amount of tape to secure the replacement part while the first side is secured.
Affects Serial Numbers (roughly) less than 350.
