KAT100-2 project

[VE3WDM]

Good morning all, I have the K2 serial number 6612 it has the KPA-100 installed I am in the process of converting it into the KAT100-2 along with KAT100.
Below are some questions
In the manual I am told to remove C44 from the control board that is beside U1 in the K2. I noticed this cap was never installed in the first place. I assume this step in not needed in my case? My board is REV B3r.
Because my K2 did have the KPA-100 installed but now is going into the KAT100-2 enclosure is there any menu settings in the K2 that have to be changed around?I noticed there is a black cap over the BNC connector on the K2 as the KPA-100 was installed, when operting QRP to use this connector is there any menu changes that have to be made?With the K2 back to stock power (no KAT-100) there is no ground screw with the old cover re-installed. I like to run a counterpoise during portable operations. Is there a way of installing a thumbscrew ground connection? I also now have to install the KIO2 in the K2 now as well. I noticed in the KIO2 manual on page 10 there is a wiring modification does my K2 need this mod with the serial number of 6612? Thanks very much for your time

Mike,

For your K2 or any others above SN3000, those changes mentioned in the
KPA100 manual have already been made.

There is no difference in the K2 board wiring between mounting the
KPA100 directly on the base K2 or mounting it in an external enclosure.  
That information is for those having older K2s that have not yet been
modified or upgraded.

Yes, you will have to remove the boot on the K2 BNC jack when the KPA100
is mounted externally (unless you have the KAT2 installed in the QRP top
cover.

Yes, you will need the KIO2 or a suitable substitute to carry the
signals needed by the KPA100 from the base K2.  Those signals are on the
ribbon cable when the KPA100 is mounted on the base K2.  The KIO2 merely
acts as a 'conduit' for those signals - it has nothing to do with the 3
RS-232 signal lines in the AUX IO connector.  Also note that when
remoting the KPA100, you will lose the ability to connect the AUX IO
connector on the KPA100 to a computer.  If you need the computer
connection, you will need to add the KIO2.

If you have the KAT2 installed in the top cover, there is a 5 way
binding post provided for a ground.  If you want a ground connection
without the KAT2, add one to the hole in the top cover labeled GND (or
something like that).  A 5 way binding post can be used, or simply a
6-32 machine screw, 2 nuts and 2 washers will do fine.  Be sure to
scrape some paint off the inside of the hole so you have a good
connection of the screw head to the aluminum.

73,
