Amateur radio construction – Steve G0FUW and Pete N6QW
Despite what many people think, building your own radio equipment is still a very popular aspect of amateur radio.
In fact there has never been a better time to do this, with readily accessible building blocks and high spec test equipment available at bargain basement prices, or, in the case of software, absolutely free.
This presentation covers the reasons why people homebrew radio equipment, share some ideas on how to get started and provides some examples of homebrew gear, and using hardware and software.

As part of the national “Get on the air to care” campaign with the NHS, the RSGB Tonight @ 8 series of live webinars cover a range of topics and help you gain more enjoyment from amateur radio.
Tonight @ 8 webinars are live-streamed, allowing you to watch the presentations and ask questions online. They can also be viewed on a later date on the RSGB website and YouTube.

Deze avond zal Arjan Kievits een lezing verzorgen rond het thema Deep Space Communicatie.
Arjan is geen zendamateur maar wel werkzaam als technisch consultant Wi-Fi voor de grootzakelijke markt, heeft als hobby astronomie en is betrokken bij de sterrenwacht in Spijkenisse.
De lezing gaat over radiocommunicatie, maar dan net een beetje anders. Zo komt bijvoorbeeld aan bod hoe New Horizons zijn foto’s van Pluto naar Aarde heeft kunnen sturen. Maar ook hoe we nog steeds wat van de Voyagers horen.
Wat is dit allemaal en hoe kan dat nu? Om dat te begrijpen worden de basisbegrippen van radio-communicatie kort toegelicht, samen met een stukje digitale communicatie. Er komt wat techniek aan bod, we gaan ook nog een beetje rekenen. En er wordt een uitstapje naar Wi-Fi gemaakt, wat iedereen natuurlijk kent. Waarom? Tja, dat is nog even afwachten.

Starting out on the microwaves bands – Neil G4LDR
‘Starting Out on the Microwave Bands’ will provide basic information needed to understand the microwave bands and how to become operational on them.
Topics covered will include:
- What are the microwave bands
- Propagation properties and microwave beacons
- What classes of licence can use which microwave bands
- Equipment requirements including antennas and transverters
- Examples of typical equipment including simple wideband systems
- Operating on the microwave bands including satellites, contests and activity periods
- Resources to help you get going on the microwave bands
Those who become operational on the microwave bands will find there are plenty of opportunities to try the many aspects of this part of the hobby. These include operating portable from a hill top using relatively simple equipment; satellite operating; DXing; trying different operating modes including CW, voice, digital and even DATV; right through to probably the most challenging part of the hobby, moonbounce or EME.
