[Elecraft] Elecraft K2/10 Upgrade

[Don Wilhelm]

Rick,

You can simply add the KPA100 and install the VCO ALC and 10/12 meter 
bandpass filter Mod kit that comes with the KPA100 kit, and it will work.
However, I recommend doing a full upgrade.  Look at the K2 A to B 
instructions to see the list of additional Mod kits (remember that the 
10 meter bandpass and VCO ALC kit is included with the KPA100 kit).  The 
K2KEYMODKT is not available from Elecraft due to a lack of the PIN diode 
specified, but email me direct and I can send you the instructions and a 
list of the parts to order - new K2 kits use a pin diode on a small 
carrier board for the diode needed.
If your firmware is not upgraded to 2.04, now is the time to upgrade it.
In addition, I highly recommend that you upgrade the IF crystals as well.

Is it worth it?  Only you can answer that, but I can tell you that after 
the upgrades, the K2 will be the performance equal of a newly 
constructed K2 except for a few inconsequential items.  The cost for the 
mod kits, new IF crystals, and new firmware will be in the vicinity of 
$130 or less.

73,
Don W3FPR
