Meetings continue online via our Wednesday evening Skype sessions, which members are welcome to join. If you wish to contribute, please email Mike.Lang@btinternet.com giving me your skype id, and I will ensure that stephen calls you in. Club meet starts at 7.00 pm approximately, and can continue sometimes for 2 hours plus.
If you need help we can advise how, or where to look, if we don’t know the answer. ]]>
Topic of the evening was Oscillators
This circuit was widely used in the regenerative radio receiver, popular until the 1940s.
Clapp Oscillator – Another oscillator which is an advanced version of Colpitts oscillator
Colpitts Oscillator Tutorial and the theory behind the design of the Colpitts Oscillator
Hartley oscillator using transistor, circuit
A Meissner Oscillator or sometimes (especially in USA) refered more as an Armstrong oscillator
Wein Bridge Oscillator
All took part in a new reflector experiment for the club, this is so we can talk without interfering with other YSF reflector rooms, the test hardware will be replaced with more capable modern PI, but a PI B overclocked managed a small group test.

]]>Your find that everyone has a slightly different take an what the hobby is, however a general consensus could be a science based experimenting hobby.
There is no right or wrong choice in a hobby that will take you wherever your interest leads:-
Maybe you want to make long distance contacts via Dxing
Maybe you want to experiment with computer based data modes
Maybe you want to construct a receiver or similar electronics
the club doesn’t charge a yearly subscription- instead a £2 per visit charge which covers hire of the room and a tea or coffee and a biscuit
