phalconphixer. Oh yes the joys of the PTR change and even better trying to replace the PTT foot switch in the rear cockpit. as for the HF that was fitted behind door 61L above the Stabilator PFCU. 99 screws in door 61L and they had to be removed every 30 days to check the pressurisation of the T/R and antenna coupler. The Rad Alt T/R was another bloody nightmare to replace as well, the panel was too high for you to sit under to remove it and too low to stand under meaning you had to remove it in a painful half crouch and almost invariably you would find something nice and sharp to dig into your back as you moved about under the aircraft. Oh the Joys of being a Phantom Phixer!
