Norfolk to Yorkshire - May 9th and 10th

Post by g8gtz » Sat Apr 28, 2018 11:42 am

A rather optimistic group of people are planning to try and snatch back the 5665 record by attempting the Norfolk to Yorkshire 160+ Km path.

The Northern team including G8AGN, G0RPH, and M0DTS will be at Flamborough head and G8GTZ, G4NJJ, G8JAN and M1BKF will be in the Cromer area on Wednesday 9th.

The path is not Line of Site and will need some form of enhancement but it is probably too early for hot summer ducting as described in this paper http://www.df5ai.net/ArticlesDL/VK3KAQDucts2007V3.5.pdf

We will post more details as and when plans develop and any interested parties are welcome to join in the fun.

"North-west group seeks supplier of reflective hot air balloons in the Mablethorpe area". :D

Good luck.

The Norfolk site is now confirmed as the Seaview Beach cafe car park in West Runton - http://www.seaviewbeachcafe.co.uk/?p=seaview.car.park

QRA = JO02PW at http://k7fry.com/grid/?qth=JO02PW05BW - height is only 50 ft ASL (high for Norfolk) but direct view to the sea and very convenient for a cuppa and the loo :-)

Primary band is 5665 but I will have also have 146MHz and possibly 70cms (10 or 24GHz by request).

Talkback = 144.750 or 07881914287

We'll be on site from around 10:30 and anyone in the area is welcome to visit.

Thanks to the efforts of Richard G0RPH and Barry G8AGN who traveled up to Bridlington the 5665MHz ATV record now stands at 158Kms between IO94VB45TP and JO02OW95RW and the honours now rest with the East Coast team :-)

This was a non Line of sight path and we believe propagation was by a surface duct formed between the very cold sea and relatively warm and moist calm air above it forming a temperature inversion. Both teams were no more than 50ft above the beach so had good entry in to the duct.

During the contact a very distinctive dark haze approximately 20 -30 metres high was visible out to sea - after the contact the wind speed increased, the temperature dropped and the duct disappeared.

Due to the ducting effect, the signals levels were a good P4 / P5 and at one point G4NJJ received the G8AGN signals just using a clover leaf antennae!

All equipment was the <£20 drone equipment - G8GTZ and G8AGN were running ~2watts but other stations were running 600 milliwatts.

The Norfolk team consisting of G8JAN, G4NJJ, G8GTZ and M1BKF were joined by members of the Norfolk Amateur Radio Club who were so impressed with what could with a £20 rig that a number of them are planning to buy equipment :-)

Both teams had great fun in the fine weather but we do not expect to hold on to the record for very long!
