[Elecraft] SDR on K3 IF to look for RFI

Now that 160 season is almost over and my antenna farm is doing good I'm
going to start chasing RFI at my new QTH.

I plan to use my RSP2Pro with HDSDR to do some time lapse recording to see
when things come and go as a first step.

To do this I plan to use my existing antennas and I'd like to avoid
connecting and disconnecting my rig as much as possible.

So I'd like to use the IF port of the K3s. That's currently passed to the
P3 and I thought I could use its IF output to drive the SDR.

That would allow me to leave it connected all the time even while using the
K3 for normal use.

How wide is the bandwidth of that port? Is it limited to the 200Khz the P3
presents?

Thanks
