Essex & Herts Air Ambulance Event Sept 2021

In September 2021, Essex Ham once again supported International Air Ambulance Week. We were at Earls Colne Airfield, the home of the Essex & Herts Air Ambulance on Saturday the 11th of September, operating with the callsign GB4EAA.

IAAW is a nine-day amateur radio event to support the work done by Air Ambulance services around the world, and we’re proud to have been able to support the Essex & Herts Air Ambulance for this year’s event. The following video gives an overview of the event:

Supporting the event

We hope that as many of you as possible will be able to make contact with GB4EAA. We aim to be on-air from 10.30am until hopefully 5pm on HF and 2m – frequencies will be announced on Twitter. If you’re collecting the IAAW award, our Air Ambulance Station Number is A012.

Everyone’s welcome to attend – and hopefully to do some operating.  Come along to help support the event, and spend some time with the team at Anglian Flight Centres, a busy flying school. 

Attending / Visiting GB4EAA – What you need to know.

  • We have a limited space from which to operate. For this event, you will not be able to bring along your own radio kit and set up your own station unless it has been pre-arranged with Pete M0PSX – this is due to restrictions at the location. (If you want to operate and use your own radio for Covid-reasons, this can be arranged)
  • We are guests of the Anglian Flight Centres, an active airfield. We must obey their rules at all times, including Covid restrictions. Visitors to GB4EAA should report the Essex Ham station to be briefed. Access to the apron, aircraft and air ambulance hanger is restricted for obvious reasons
  • In previous years, we’ve been lucky to see several aircraft launches as well as operate HF and VHF stations. As this is an active airfield and the Air Ambulance is on-call, there are no guarantees.  
  • There’s free parking at the airfield, and on Saturday, we’re very close to a burger van for excellent breakfast and lunch. The flight school has basic tea-making facilities in return for a small donation, and they kindly allow us to use their loos.
  • Essex Air Ambulance is a registered charity. Essex Ham asks that all visitors to GB4EAA make a donation to the Essex Air Ambulance. A collecting tin will be available during the event. Please show your support and make a donation. Please bring some cash!

Please keep an eye on Essex Ham’s Twitter feed for updates on the event.
