Background Information

B3KEU – Microwave Beacon

A 5.7GHz microwave beacon, GB3KEU, was running from April 2008 until mid March 2014 from the Sheffield Amateur Radio Club location at Meadowhead, Sheffield. We “threw the big switch” at 11.15GMT Sunday 6 April.

Sadly the beacon has had to be removed from the SARC HQ,  as the committee, guided by its Chair and Vice Chair asked for a site rental fee (it had been housed for free for the past 6 years), restricted the unlimited access by the beacon keeper, as required by OFCOM,  and obviously preferred it to be taken away!

At the moment (April 2014), it is in the shack of G3PHO awaiting some refurbishing and will hopefully soon be QRV again but from the home QTH of G3PHO in IO93GG. We are just waiting for Ofcom to approve the site change. If this is going to take months the beacon will be activated as a personal attended beacon under the call sign G3PHO/B until GB3KEU clearance comes through.

The technical details remain the same and are shown below …

  • Callsign: GB3KEU (In memory of Tim Leighfield, G3KEU, a keen 6cm op and now SK)
  • Frequency: Nominally 5760.925MHz
  • Antenna: Slotted wave guide. Omni.
  • Power out: 25W erp
  • Keying: FSK, nominally 400Hz shift.
  • Line up: G8ACE OCXO-> DB6NT 5.7 beacon module -> DB6NT PA (at reduced o/p)

We all owe a debt of gratitude to Peter, G3LRP (nr Wakefield) for his extremely generous donation of both DB67NT modules to this project. He waited a very long time to hear this beacon! Many thanks also to the Telford club, G3ZME very kindly donated (via G3UKV) a beautifully made slotted waveguide antenna.
