[Elecraft] K3? KXV3A RX Ant, IF Out & Xvrtr Int question using LP-PAN, w/ Rev. B RF board

[Alan Bloom]

Hi Dave,

Go to http://www.elecraft.com/ and clock on "K3 Mods + App Notes".
Scroll down a couple entries and click on "IF Output Buffer Gain
Modification" to get the complete instructions.

The resistor is a 13k by the way.  The value is not critical; a 12k
would work fine.  It can either be a leaded or surface-mount type.
