David Kilpatrick from TXAustralia takes us on a detailed tour of the old decommissioned 10kW analog TV transmission system at the Artarmon facility in Sydney. How it all works from the broadcaster video input to final transmission output up the 180m broadcast antenna. Plus some teardowns of the old equipment …

What is the actual capacitance of typical breadboard contacts? It’s not in the datasheet, so Dave decides to measure it. It is well know that breadboards are not suitable for high frequency work due to the stray capacitance between contacts, but how bad is it really?
