Presentation – Radar vs. U-boats

22 Aug

Join Captain Jerry Mason (USN ret.) VE7YAB for another of his fascinating presentations on German WW II U-boat radio and radar systems.  7:00 pm Tuesday September 18 at Red Cross House, 909 Fairfield..

“Radar vs. U-boats” will cover the seesaw battle between Allied Radars and U-boat Radar Detectors.  It begins with the development of radar in the lead up to WWII ending with the fielding of the Chain Home radar network operating in the HF-band.  Then the first air and ship borne radars operating in the VHF-band and the first German radar detectors.  Next, and arguably the greatest technical development of the war, the cavity magnetron enabling compact, lightweight radars operating in the S-band and the German response.  Lastly the fielding of radars operating in the X-band and the most advanced German radar detectors.

Ham Class antenna making

7 Apr

 

We are close to the end of this year’s course.  Today we were making antennas, and Graeme looks very pleased with the results.  Many thanks to Donn VA7DH for machining a lot of plastic components, and to Ed VA7SDH for patiently giving glowing signal reports as we tried each new antenna on the air.
