[Elecraft] KIO3B waiting list

[Edward R Cole]

Lots about this option, but what exactly does the upgrade provide 
over the standard board?

My K3, SN4340 dates from 2010 so assume it has a KIO3 board (not sure 
if A or B version).  Trying to determine if I want/need the upgrade.

I did add EXREF, TCXO3, upgraded both Synth boards and Gen Coverage 
filter to cover 475-KHz (630m) band.  I have the subRx installed.
