As part of the RSGB Tonight at 8 video series, Tim GW4VXE gave an interesting presentation on digital voice modes like D-Star, DMR & Fusion. This is really aimed at beginners or anyone who is not familiar with these modes.
The video is shown below. The presentation lasts from about 06:00 to 1:09:30 and there is a Q&A session after it which lasts until 1:43:40.
As part of their ongoing lecture series during the COVID-19 pandemic, the RSGB had a presentation on Monday the 28th of September 2020 from Tim Kirby, GW4VXE titled 'My World of VHF'. Tim writes a popular VHF column in the Practical Wireless magazine as well as writing for other radio related publications.
In the presentation, Tim gives an overview of amateur radio operation on the various VHF and UHF bands and is a good introduction for anyone who is not aware of what these bands have to offer. The first 9-minutes of the video concern the upcoming online RSGB convention and Tim's presentation starts after that.
