Steve,

Although the KRX3 provides no external connection to the 1st IF, I 
have made a modification to do so (very easily).  Details are on my website at:
http://www.kl7uw.com/LINRAD.htm
This webpage deals with making an adaptive receiver using the K3 wit 
KRX3.  Scroll down the page to the heading:
Connecting K3 Sub-Receiver IF to LP-Pan:
I tap the IF using a .001 uF disc. ceramic cap to connect at w-3 or 
pin-1 J78 on the sub receiver pc board using RG-174 coax cable which 
is run thru a hole in the KRX3 shield to the aux BNC connector.  The 
main receiver IF connection on the KXV3A is undisturbed.

This is how I accessed both IF's for adaptive diversity reception for 
2m-eme by feeding the IF to two LP-Pan.

Hi,

Just about to throw the switch on a KRX3 order.  Going over the 
manuals I see no way to attach the IF-out of the
KXV3A to the sub-receiver.  It seems natural to use the panadapter on 
the sub to watch other bands while working
with the main rx.  Am I missing something, or must the IF-out come 
from the main rx?  I already have the KXV3A
installed, I will be adding the KRX3, along with additional filters 
for the main rx.
