I've been using a Perseus SDR as a

recommend ignoring K3 IF OUT; use K3 RX ANT OUT instead.
This works with many radios, not just the K3
There are many advantages to doing it this way:
- No significant loss of sensitivity (just 3 dB from
The IF out signal loss is only 3 dB or so more than that with
preamp off and actually has gain with preamp on.
- The panadapter span is not limited by the bandwidth
of K3 IF (200 kHz?); you can monitor the entire band
with the Perseus, not just a small portion
I believe the K3 IF bandwidth (pre-crystal filter) is much
greater than 200 kHz. I think it is limited only by the
front-end filters - you should be able to scan the whole band.
