This event is being organised By Ewan 2E0HOE.

When: 

∙ Thursday 20 June 2024 

∙ Briefing at 7:30pm local time, first team  will start straight after. The start and  end times will be recorded. 

Where: 

∙ Sydney Arms Pub, Old Perry Street, BR7 6PL (Sidcup/Chislehurst border near Frogpool Manor.  Halfway between Chislehurst War Memorial and Queen Mary’s Hospital) 

∙ The pub has a car park and garden. Additional on-street parking is available and there is another  car park nearby 

∙ The recommended entrance for the hunt is almost opposite the pub, leading into Scadbury Park  Nature Reserve 

∙ The evening is social. Those not competing are welcome to attend… food/drink etc.

Car Park Entry requirements: 

∙ Individuals or teams may enter in the same category. Members of a team may not split up ∙ No more than one receiver may be switched on at a time in each team 

∙ Only conventional equipment may be used – antenna, attenuator, receiver etc. No doppler DF  equipment permitted. 

∙ GPS, mapping and magnetic compass equipment are all permitted 

Equipment minimums: 

∙ A receiver (or transceiver) for 2m FM, (battery operated/portable). A radio with a built in S meter makes things easier but isn’t essential. Choosing a ‘selective’ radio will help. Cheap radios,  many Baofeng being an example, will struggle when overloaded by strong adjacent signals. The  effectiveness of your equipment’s internal screening/shielding is also important when close to a  transmitter 

∙ The receiver should be capable of tuning to a Beacon transmitters at 25kHz spacing at the top end of  144MHz. They will periodically identify in CW/Morse with a tone modulated onto an FM carrier –  G3RCV . There is no requirement to be able to decode the CW as there will only be one transmitter – ∙ 

∙ A portable directional antenna.  The transmitters are vertical  polarisation. 3 element tape measure YAGIs are a popular  antenna choice – many designs are  published online 

∙ Attenuator. Switched/stepped  versions work well 

∙ Sturdy footwear for woodland  paths. 

∙ Clothing appropriate for the  weather – rain or shine! 

∙ Torch (depending on your start  time) 

∙ A pen/pencil and any other stationery items 

What to expect: 

∙ Start times will be informal  

∙ Start and stop times will be recorded at the pub 

∙ There will be one transmitter to be found. it will not be visible from paths, but easier to spot up  close, around head height, marked with an A4 laminated sign 

∙ A ‘codeword’ should be recorded to prove that you found the transmitter 

∙ Your end time will be noted when the last member of your team passes through the door/gate  of the pub 

Additional info: 

∙ If you have hunting equipment to loan, please let me know (contact number below). I  have one set to loan 

∙ If you are happy to host a DF novice in your team, please let me know (contact number  below) 

∙ If you’re new to direction finding and you’d like to join an existing team, please let me  know (contact number below) 

∙ If you would like to borrow equipment, please let me know (contact number below).

∙ Do you like a project?! Why not build a tape-measure Yagi? Maybe  even a switched attenuator? Or, if you’re looking to ‘up-your-game’,  how about an “offset attenuator”?
