Welcome to RADARC

Thames Valley’s leading Amateur Radio Club since 1934.

RADARC is a very active amateur radio club.

In addition to on-air nets, face to face meetings have  resumed with appropriate precautions. Given the popularity of online meetings, we are keeping these going. So (as a rule) it’s your choice whether to attend meetings in person or virtually: so-called  “hybrid” meetings.  Activities usually take place on Thursdays starting shortly after 8pm.

Further online interaction happens via the ‘Discord’ messaging application, introduced as an experiment in response to the pandemic. It is now a thriving internal discussion and collaboration forum. This is alongside the existing Google group.

In the summer we run social and practical events/sessions (“antenna evenings”).

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.

  • G4JTR Top Band Net

    29th February 2024 @ 8:00 PM - 11:00 PM

    Hi to all Club members

    Following the success at the end of November, another experimental Club net on Top Band, on Thursday eve. 29 th February starting at 20.00hours.

    I have been asked to co-ordinate this by John, G4RDC and I’m happy to do this.

    I understand that not many members will have this capability at the moment but here is an opportunity to see how well you can lash up a system for local contacts. I suggest the following simple approach. 

    Antennas.

     We are not looking for NVIS ionospheric propagation, what is needed for a local net of stations a few Km apart, I think,  is local ground wave propagation. This means having some component of radiation with vertical polarisation  from the antenna.  An inverted L is ideal. It can be non-resonant  and shorter  than a 1/4 wave, provided your ATU will resonate it.   The ATU can be at the feed point  if you use a remote auto ATU, or in the shack, where the coax feeder will act as a crude counterpoise.   An additional  wire  counterpoise  at the feed point may probably help but not necessarily.

    Strapped feeders on a doublet is good.  A short loaded vertical resonated on top band,  if you already have, one will work.

    If you run a full sized antenna for more serious Top Band work, I expect it will be fine for local contacts.

    Power Level.

    I am proposing a net frequency  of 1850KHz  LSB or just below in the high power all mode section of 1840 to 1850KHz. The lowest dial reading we can use on LSB is 1843KHz. This means we can use in excess of 32W   but I will probably limit my power to 50W. Your power  may be limited by “RF in the shack” issues.

    So, in summary, I will call on 1850KHz at 20.00 on the 29 th.  Or on  the best frequency clear of QRN  just  below and co-ordinate the net as Net Controller and pass it round according to the list of callers.

    Best of Luck,

    Vin, G4JTR.
