Specification 284D &P, issued on 7 December 1972, which comprised a revised instrument layout, included the replacement of the Eureka DME receiver, the single UHF radio and G4 compass with a VOR instrument landing system, civil DME, VHF radio, Sperry CL 6 Compass and a stand-by Ferranti Altitude Indicator . Ninety-three T Mk.5s were also upgraded to T Mk.5A
I would be interested to learn of anyone who was a member of the elusive third course - No.125 (Jet Provost) Course March - November 1957 - at No. 2 FTS, Hullavington, flying the Jet Provost T Mk.1? It did actually exist because it is mentioned in a contemporary Air Ministry document
Not sure this is completely accurate. My recollection of the JP fleet of 3a and 5a aircraft at 1 FTS in the 70s and 80s was that only the 5a's had VHF R/T. The 3a's had a UHF box and a Standby UHF box that could Rx/Tx on 243 and 243.8.
Edit. I think the 3a's had an ARC 52 and the 5's had a PTR 175
