The following is for installing Linrad under Windows XP, Vista, or Seven (only).
configuration planned for use with Linrad.
Connect LP-Pan to K3 IF output (BNC cable).
set up with soundcard input with FFT=16 kbps and RBW=5.9 Hz; mild smoothing=2 and scale= 2dB.
Display will depend on the spectrum software that is run.
The K3 provides IF output for the main receiver but not for the sub-receiver (KRX-3).
first mixer at jumper "w-3".  This is also pin-1 of J78, the noise blanker connector.
present at p86A. It is soldered at the eyelet adjacent to w-3 and J78, pin-1.
Strip an eight inch piece of Belden 7805 RF100 RG-174 coax cable and remove about 3/4-inch of the jacket.
Comb out the braided shield and twist to make a tight ground conductor.
Slip some heat-shrink tubing over the twisted shield so 1/4 inch is exposed.
trim one lead of a small .001 uF disc. cer. capacitor to 1/4 inch, bend one lead and insert 1/8-inch in the hole adjacent to "w-3"
the foil shield of the center conductor; 3/8 inch of the coax should extend beyond the beads.
strip 3/16 inch of the coax and solder to the unconnected capacitor lead.
Solder the coax shield "wire" to the tinned metal shield of the KRX3.
Solder it down at the junction of the KRX-3 pc board so the KRX-3 cover can still seat without interference.
reinstall the noise blanker pc board.
Route the coax cable up thru the largest hole in the metal KRX-3 cover, install the sub-receiver cover.
Once the KRX3 cover is secured, run the coas thru a small toroid winding the coax thru twice.
The other end of the coax will be connected to a BNC female connector inserted into the hole reserved for the XV144 antenna.
Connect one of the LP-Pan to the sub-receiver IF BNC connector.
of U11 to 1.5 Vpk-pk but its gain boosts it to over 2.5 Vpk-pk which is enough to drive both LP-Pan.
