I believe the Vulcan RWR was also fitted to our Chinooks just before deploying to Akrotiri for ops into Beirut. After an approx 45 min lecture (mostly audio tapes of different WP radars 'believed' to be in Lebanon) about it, I was able to identify and listen to the GunDish radar as fitted to ZSU 23-4 scanning for us on our entry into Beirut and locking on as we exited (below 100ft). Happy Days.
I should add I recognised the Gun Dish thanks to maritime training and nothing to do with the Odiham lecture
