[TVI-RFI-EMI] ferrite beads

[FireBrick]

I'm building a patch cable from the sound card to the packet connector and
fsk connector of my FT1000MP.
On the packet connector there is audio in and out.
On the FSK connector this is only audio out and FSK control.

I'm using a high grade twisted, shielded cable.
I have a bunch of tiny ferrite beads I bought long ago.
Should I put the beads on both the audio in/out AND it's ground wires or
just the audio in/out side of the circuit.
The cable will have audio transformers at the rig end to minimize rf
looping.

I've got plenty of beads so that's not a problem.
So should I put them at both ends of the cable?

I don't have a big rfi problem but want to minimize the chance as much as
possible.
