In 1941 at the young age of 19 he started at Bletchley Park as an intercept operator. The bay he worked in contained two HRO receivers, each operator being given a specific list of signals to listen for.

After the D-Day Allied invasion of Europe in June, with the small mobile unit headed to Normandy under the direction of Tricker who was now a Major, Pat went to Normandy, where he remained until August. He subsequently travelled to Paris, Brussels, Eindhoven, etc. and into Germany, with the same British intelligence services unit, mainly to report German troop movements and to connect 21st Army Group with Secret Intelligence Service field agents and SUSSEX intelligence teams.","At the end of October 1944 he was assigned as a personal operator for an Intelligence officer heading for Nijmegen (Nimeguen) in the Netherlands, and was provided with a double transposition poem cipher (LMT cipher) , which was unprecedented in the Ml6 as radio operating and ciphering were usually separate. [Double transposition was generall y regarded as the most complicated cipher that an agent could operate reliably under difficult field conditions]. At Nijmegen he became involved with the IS9 which was another 'private army' and which organized escape and evasion of Allied troops and breakaways. For a brief time in 1945 he worked with Holland's Bureau of National Security. At the Abbe Museum in Eindhoven, which served as British Intelligence headquarters, he worked for the remainder of the war as chief operator in a Dutch network for cipher de-coding, he being the only English speaking person there. At war's end in Europe, Pat rejoined SCU9 in the British Zone of Germany, sending six months in Rhineland and gaining much insight into the complexities of the utmost secret intelligence operations. After the war Hawker was regarded as an authority on clandestine radio. He became a key figure in British radio and television, and was Vice President of the Radio Society of Great Britain (RSGB) .

In 1941 at the young age of 19 he started at Bletchley Park as an intercept operator. The bay he worked in contained two HRO receivers, each operator being given a specific list of signals to listen for. In April 1943 he was transferred to Section VIII unit, and served at Weald Station as a two-way radio operator, under Morse code expert Captain Robert Henry \"Harry\" Tricker. In 1944 Pat joined unit SCU9 and was sent Into war zones where covert communications were required . After the D-Day Allied invasion of Europe in June, with the small mobile unit headed to Normandy under the direction of Tricker who was now a Major, Pat went to Normandy, where he remained until August. He subsequently travelled to Paris, Brussels, Eindhoven, etc. and into Germany, with the same British intelligence services unit, mainly to report German troop movements and to connect 21st Army Group with Secret Intelligence Service field agents and SUSSEX intelligence teams.\u003c/p\u003e\n      ","\u003cp\u003eAt the end of October 1944 he was assigned as a personal operator for an Intelligence officer heading for Nijmegen (Nimeguen) in the Netherlands, and was provided with a double transposition poem cipher (LMT cipher) , which was unprecedented in the Ml6 as radio operating and ciphering were usually separate. [Double transposition was generall y regarded as the most complicated cipher that an agent could operate reliably under difficult field conditions]. At Nijmegen he became involved with the IS9 which was another 'private army' and which organized escape and evasion of Allied troops and breakaways. For a brief time in 1945 he worked with Holland's Bureau of National Security. At the Abbe Museum in Eindhoven, which served as British Intelligence headquarters, he worked for the remainder of the war as chief operator in a Dutch network for cipher de-coding, he being the only English speaking person there. At war's end in Europe, Pat rejoined SCU9 in the British Zone of Germany, sending six months in Rhineland and gaining much insight into the complexities of the utmost secret intelligence operations.

Hawker was involved in many aspects of radio, beginning in World War II as a member of the Radio Security Service (RSS) and its connections to British Security Service Military Intelligence Ml5 and the Secret Intelligence Service Ml6. In 1941 at the young age of 19 he started at Bletchley Park as an intercept operator. The bay he worked in contained two HRO receivers, each operator being given a specific list of signals to listen for. In April 1943 he was transferred to Section VIII unit, and served at Weald Station as a two-way radio operator, under Morse code expert Captain Robert Henry \"Harry\" Tricker. In 1944 Pat joined unit SCU9 and was sent Into war zones where covert communications were required . After the D-Day Allied invasion of Europe in June, with the small mobile unit headed to Normandy under the direction of Tricker who was now a Major, Pat went to Normandy, where he remained until August. He subsequently travelled to Paris, Brussels, Eindhoven, etc. and into Germany, with the same British intelligence services unit, mainly to report German troop movements and to connect 21st Army Group with Secret Intelligence Service field agents and SUSSEX intelligence teams.","At the end of October 1944 he was assigned as a personal operator for an Intelligence officer heading for Nijmegen (Nimeguen) in the Netherlands, and was provided with a double transposition poem cipher (LMT cipher) , which was unprecedented in the Ml6 as radio operating and ciphering were usually separate. [Double transposition was generall y regarded as the most complicated cipher that an agent could operate reliably under difficult field conditions]. At Nijmegen he became involved with the IS9 which was another 'private army' and which organized escape and evasion of Allied troops and breakaways. For a brief time in 1945 he worked with Holland's Bureau of National Security. At the Abbe Museum in Eindhoven, which served as British Intelligence headquarters, he worked for the remainder of the war as chief operator in a Dutch network for cipher de-coding, he being the only English speaking person there.

Hawker was involved in many aspects of radio, beginning in World War II as a member of the Radio Security Service (RSS) and its connections to British Security Service Military Intelligence Ml5 and the Secret Intelligence Service Ml6. In 1941 at the young age of 19 he started at Bletchley Park as an intercept operator. The bay he worked in contained two HRO receivers, each operator being given a specific list of signals to listen for. In April 1943 he was transferred to Section VIII unit, and served at Weald Station as a two-way radio operator, under Morse code expert Captain Robert Henry \"Harry\" Tricker. In 1944 Pat joined unit SCU9 and was sent Into war zones where covert communications were required . After the D-Day Allied invasion of Europe in June, with the small mobile unit headed to Normandy under the direction of Tricker who was now a Major, Pat went to Normandy, where he remained until August. He subsequently travelled to Paris, Brussels, Eindhoven, etc. and into Germany, with the same British intelligence services unit, mainly to report German troop movements and to connect 21st Army Group with Secret Intelligence Service field agents and SUSSEX intelligence teams.","At the end of October 1944 he was assigned as a personal operator for an Intelligence officer heading for Nijmegen (Nimeguen) in the Netherlands, and was provided with a double transposition poem cipher (LMT cipher) , which was unprecedented in the Ml6 as radio operating and ciphering were usually separate. [Double transposition was generall y regarded as the most complicated cipher that an agent could operate reliably under difficult field conditions]. At Nijmegen he became involved with the IS9 which was another 'private army' and which organized escape and evasion of Allied troops and breakaways. For a brief time in 1945 he worked with Holland's Bureau of National Security. At the Abbe Museum in Eindhoven, which served as British Intelligence headquarters, he worked for the remainder of the war as chief operator in a Dutch network for cipher de-coding, he being the only English speaking person there. At war's end in Europe, Pat rejoined SCU9 in the British Zone of Germany, sending six months in Rhineland and gaining much insight into the complexities of the utmost secret intelligence operations. After the war Hawker was regarded as an authority on clandestine radio. He became a key figure in British radio and television, and was Vice President of the Radio Society of Great Britain (RSGB) .
