[Observer1940]

Andy, Peter and Steve

Agree with Group Appendices or possibly even Fighter Command Appendices.

Regarding my previous mention of C.D.75 this relates to "Air Force Code" more likely to be additional codes to the standard Q Code.

Just found this for August 1940 in the No. 1 Group Appendices I have photographed:-

Station R/T Call Signs
Finningley PUKKA
Driffield Angora
Wick DUNCAN
Bassingbourn AURORA

H.F. D.F. Call Signs (Separate Call Sign for Guard Frequency)
Abingdon C6A. CUTTA
Wyton 8HX. GUARDIAN
Waddington 6JH. ALVIS
Linton 07U. ISLANDER
(Leuchars ZC8. MALLARD
(Evanton

Which also gives the following publication in August 1940:-

C.D. 14/1(2) "RAF W/T and R/T War Call Sign"

Done a TNA, Kew, search "W/T and R/T" with no dates and no Dept Reference Series and downloaded quite a few returns, but one in particular relating to Call Sign (undated) is:-

AIR 10/3852 Ministry of Defence and predecessors: Air Publications and Reports. SIGNALS (Code No 6). GENERAL (Code No 6/1). Block Allocation of R.A.F. W/T and R/T War Call Signs. Open from 1972. AP No. CDO237(3).

No covering dates, but might or might not be worth a look at?


There might be something of interest in (Retained Until 2004):-
HW 50/31 R/T (HF and VHF) and VHF (W/T and R/T - wireless telegraphy and radio telephony): Organisation at home and abroad - Army, Air Force, Naval. Notes on development from beginning until Spring 1942; Evolution and organisation of Coastal 'Y' Stations (final version and initial material)
