K2 accessories order

I have K2 SN 00057. It is the most basic it can be. I stopped once it was
working even though I had lots of the original add-ons because I was simply
having too much fun.

So, here is my dilemma: I have ALL of the options except the KPA100,
including updates & DSP, but have not yet installed any of them. I hope to
even get the KPA100 for a combined late October birthday/Christmas. Does
anyone have a list of a) what order I SHOULD install them in; & b) which
ones should NOT be used with any others? (I understand the battery and I
THINK the internal antenna tuner are not usable with the KPA100.) Thanks.

Re: K2 accessories order

Ed,

That is a Field Test K2 serial number.
I recommend that you upgrade it with the K2ATOBKT and *all* the other
upgrade kits that are listed in the K2 A to B instructions. Do that
before considering adding any options.
I would also recommend that you upgrade the IF crystals to the newer
crystal set. If you have an old KSB2, take a look at the crystals that
came with it, and if they are not marked with an "-S" suffix, order the
set of 14 matched crystals so you have 7 to use in the base K2 and the
other 7 to use in the KSB2. If your KSB2 has the current level
crystals, you only need a set of 7 for the base K2.
If you want to change the KSB2 filter bandwidth to the newer 2.4kHz
width, add the SSBCAPKT when you build the KSB2.

Back to the base K2 upgrades, do the Alternate AF Gain Wiring Mod, and
if your K2 has been used for a significant time, replace the AF Gain
control.

Once you have added the A to B upgrades, you can start on the options.

Ed,

To further address your original question --
If you add the KPA100 to the base K2, then those options that are
mounted in the K2 top cover are not compatible with the KPA100. That is
the KAT2, KIO2 and the KBT2.

If you wish to configure it as a complete K2/10 with a KPA100, consider
mounting the KPA100 in an EC2 enclosure. That is easiest done if you
add the KAT100-2 along with the EC2 enclosure. The KPA100 plugs right
into the KAT100-2 board. That does require that you have the KIO2 in
the base K2.
