Thanks Bruce for an excellent summary of the technical situation.
I think where the British had the beating of the Germans in the field, was in the command and control system, because we were definitely behind technically until the 10cm magnetron was developed. The command and control system used the CH and other reports intelligently and was able to put the fighters where they were needed, with some exceptions. The Germans of course were far too regimental and did not really get their act together until Kammhuber got organised.
