Welcome to RADARC

Thames Valley’s leading Amateur Radio Club since 1934 – this year celebrating our 90th birthday!

RADARC is a very active amateur radio club based in Reading, Berkshire, UK.

Our activities are generally at 8pm on Thursdays, and the vast majority of our meetings are run as hybrid sessions – with both local and remote speakers, and open to those on Zoom as well as in-person audiences in all cases.

Further online interaction happens via the ‘Discord’ platform, first introduced as an experiment in response to the pandemic, and via our members’ Google group.

In the summer we run social and practical events/sessions (“antenna evenings”). Generally there is no online element to these, although you may well hear us on the air!

Our members and their activities have enabled RADARC to receive the RSGB club of the year in 2010 and 2013, and in 2016 we received the Regional award from the RSGB.

We welcome all who wish to learn about radio, electronics and indeed all aspects of amateur radio. Dates of meetings can be found on our events page.

  • New RF Transmission/Reception Research: "LAMM" by Tim M0TFR

    9th May 2024 @ 8:00 PM - 10:30 PM
    2nd Woodley Scout Group, Vauxhall Park, Vauxhall Dr, Woodley, Reading RG5 4EA, UK

    We welcome Dr. Tim Brown Senior Lecturer in RF Antennas and Propagation from the University of Surrey for an in person talk looking at the cutting edge of RF research.

    We're all used to dealing with polarisation. Combined with multiple transmitting and receiving antennas (MIMO), use of multiple polarisations can be used to squeeze the most out of an RF channel.

    Now there's something new on the block: "LAMM" or "Linear Orbital Angular Momentum" to add to the mix.

    "Like many other radio technologies used today in the modern world, the amateur radio community began the concept of using what is known as Orbital Angular Momentum to multiplex and transmit two or more signals simultaneously at the same frequency. With the idea coming from optical communications where it is very useful, it has drawbacks that limit its capability when used in radio such as short range. Therefore this led to the idea of unravelling the concept into what is known as Linear Angular Momentum Multiplexing (LAMM), something good for radio but not so good for optics. This has the potential to enable gigabit connectivity in a reliable, low cost and low energy way but it’s by using equipment commonly used in amateur radio that it becomes possible to demonstrate the concept with the hope of leading to a commercial solution."

    I'll leave it up to Tim to go into this. He's promised he'll be gentle.
