The bluffer’s guide to digital voice – Tim GW4VXE.
Tim will provide a quick overview of the most common digital modes (D-STAR, DMR and Fusion) as well as some of the less common modes. Tim will explain how you might use them.
Which mode is the best? Tim will look at code-plugs and hotspots and try and demystify some of the jargon for you.
Technology permitting, he’ll try and do a demo with the chance for a little audience participation. Rather than being a heavy session, the emphasis will be on light but informative content.

=== AFGELAST === ivm Corona maatregelen ===
Helaas is het niet gelukt om tijdig een onderwerp / spreker te vinden voor de geplande lezing op 13 april.
Vrijwel zeker zijn er binnen en buiten onze regio voldoende mensen die een interessant verhaal kunnen vertellen over onderwerpen binnen onze hobby, of techniek die daaraan raakt. Ik wil je daarom vragen om ogen en oren open te houden en bruikbare tips door te geven.
Heb je suggesties voor een lezing of belangstelling voor specifieke onderwerpen?
Laat dit dan even weten aan a22@veron.nl

The story of Jodrell Bank –
Ian G0DMU.
Professor Ian Morison, G0DMU will give a review of the history of Jodrell Bank, one of the world’s premier radio astronomy observatories; from its founding in 1945, the completion of the Mk I (now Lovell) radio telescope in 1957 – still the third largest fully steerable telescope in the world – and the building of the MERLIN array in the 1980s and 90s.
The MERLIN array has the same resolution as the Hubble Space Telescope and many collaborative observations have been made over the past 30 years. Its seven telescopes also link up with others across Europe to provide an instrument whose resolution far exceeds that of optical telescopes.
Some of its most exciting discoveries will be discussed in the context of how radio observations are made – many of which can complement those made by optical telescopes.

Radio waves and antennas … and all that – Peter G3XJE
This presentation covers a range of antenna-related information so there should be something for everyone:
What makes a radio wave? Some mysterious properties of radio waves which you might not have appreciated. How do you launch radio waves? Antennas. Radiation resistance. Radiation patterns. Antenna gain. Transmitting and receiving. Getting power into, and from, your antenna. Resonance, or lack thereof. Feeders. Feeder impedance. Matching – does VSWR really matter? Why can’t you make a monopole? Multi-element antennas. Phased antennas.
