[Elecraft] Question about P3

[Don Wilhelm]

The resistor is shipped with the KXV3 and with the P3 - those packages 
do not know the serial number of your K3 - so the resistor is included 
*if* it is needed.  The fact that you received the resistor says nothing 
about whether your K3 needs or or not.

If your K3 was ordered well after September 1, 2009 the change has been 
included, and the resistor is to be regarded as an extra part for you.

It is those K3s that were ordered close to 09/01/09 that may or may not 
have the change, and you must check (or arbitrarily change the 
resistor).  Earlier K3s do need the change installed.
