April 2016 Technical Talk

           

Satelite Anntenna

Terry, VK6ZLT was to give a talk on his experiments on using a Noise Generator with a SDR to test harmonic filters, but some experiments don't quite pan out, instead he did a short show and tell on his Quadrifilar Helix Antenna used as a base antenna to receive 2m Satellite reception. The designs for the antenna are mentioned in a past Official Bulliton MHz to GHz from August 2007 see August 2007.

March 2016 Technical Talk

Surface Mount Soldering by Terry, VK6ZLT

Terry took us through details on SMD soldering, including SM components, tools needed, flux and solder.

At the next Activity Day, April 2, there'll be a chance to try and practice techniques in soldering.
