Re: K3 ANT to IF OUT Conversion Gain
toggle quoted messageShow quoted text
I would call that a second receiver, not a panadapter/bandscope. I use an SDR-IQ with SpectraVue software for my bandscope.
SpectraVue knows all about the K3/K3S i-f output frequencies v. mode and BW so it displays the tuned frequency in the middle of the screen regardless of those adjustments (if desired, which I do). It offers point-n-click or mouse wheel tuning. There is no display smearing, refresh is instantaneous. No fuss, no muss.

I've been using a Perseus SDR as a transceiver panadapter for about 12 years now. I highly recommend ignoring K3 IF OUT; use K3 RX ANT OUT instead. This works with many radios, not just the K3.
See my presentation linked from my QRZ.COM page, or the direct link below:
The technique is the same for an SO1R station: just split RX ANT OUT to (1) RX ANT IN and (2) Perseus ANT IN using a 50 ohm "Magic T" splitter (or a 75 ohm TV splitter). A BNC "T" connector is not recommended since it doesn't isolate the two outputs.
There are many advantages to doing it this way:
Note: you must activate RX ANT on the K3, on every band, otherwise the Perseus receives no signal on that band.
