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.

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.

=========================

Now that we’ve filled our logbooks with FT-8 contacts, maybe it’s time to move on and start communicating again!

In this illustrated talk, Mike Richards, G4WNC introduces you to the best data modes for keyboard QSOs.

In addition to explaining their operation and configuration, Mike will run through some operating techniques to take the strain out of keyboard QSOs.

Have you ever considered operating while on holiday? In this presentation, Daimon covers the things you might wish to consider if taking a small HF station with you, either at home or abroad. From family, licensing, mode and other considerations, Daimon will focus on some practical examples of antennas and small stations that he uses himself to be QRV, wherever he is.

This presentation will focus on practical aspects of leisure operating as an aside to your holiday, rather than being the main component – this is not a presentation about planning DXpeditions.

=================================

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.

Terry will talk about the popular free logging software Log4OM. Suitable for all levels of expertise, Terry’s talk will look at the history of Log4OM, its developers and the in-built features of the software. There will be a live demonstration and a chance for Q&A.

The year 2022 marks the centenary of the British Broadcasting Corporation (BBC) and whilst it is well known for its programme making and public service broadcasting, the BBC has also been responsible for introducing a wide range of technological innovations such as CEEFAX, RDS and VERA, Britain’s first videotape recorder.

On this Tonight @ 8 webinar David Palmer, G7URP takes a look at some of these pioneering creations, many of which still form the backbone of modern broadcasting.
