With both Rob and Brian handling Tech night, it was full on with the oscilloscopes, including the vintage unit, with the soft yellow glowing eyes. Well done to both for a very entertaining evening.

Don’t forget we are looking for Committee members including President and Secretary, so if you would like to give either position a go, come forward and put your hand up.

 

Next Tech night,  the 25th August will be oscilloscopes.

If you have one, bring it along, and show us your skills. You might show a circuit working with one.

Talk on antenna design given by Paul Lawson VK5SL

Paul gave an in depth talk on antenna design, using a program called 4nec2
This program, allows you to type in all the measurements required, and them displays, how your antenna will work. Talk was enjoyed by all members, and note software is freeware, so members are encouraged to try this one out.

It started quiet, but the kids certainly made up for it in the end, I had plenty of participation with Morse Code again, I had my last group about 13:00, all very satisfied children, and parents I might add. Here is a few photos.
