Yup, the cable is easy.

You just take pin 2 from the 6-way futaba DIN (round) plug to the +ve (pointy bit) of the audio jack (3.5mm I think?). the screen/earth goes from the outside of the audio jack to the screen of the din plug.

looking from behind the din plug, pin 2 is the second pin clockwise from the bottom.

He suggests using a 10K pot to limot the voltage from the Tx, but my set up (futaba skysport6A, soundblaster PCI 64 and w2K works fine without it).

HTH.
