How did German spies in England in World War 2 transmit their information?

There is some information on this, but even now it is very sketchy. The idea of a suitcase & a morse transmitter is quite likely but verification of such a character as in 'The Eagle has Landed' by Jack Higgins (An Irish IRA sympathiser) is the work (I suspect) of fiction. Basil Liddell-Hart does say 'there is virtually no evidence to support this' in response to General Blumentritts' suggestion there were German agents transmitting fron southern England at the time of D day. Blumentritt goes on to say they learned nothing of where D day would eventually be. (BLH History of the Second World War p548) On the same topic however, disinformation was used by some means as the Allies trumpet the idea that the Germans accepted the idea of FUSAG (The 1st US Army Group) commanded nominally by General Patton. This non -existent force was to invade the Pas de Calais region, or so the Germans thought. One wonders just who told them !
