Early Setup at Flamborough 2013

Early Setup at Flamborough 2013

A very big thank you to all of those that made Flamborough 2013 such a great success.

This year we ran five stations covering 2m, 12m, 20m, 17m and 40m.

This was not without problems however and the club will have appropriate band pass filters installed next year for 40, 20 and 17.

I suppose it was inevitable when then were all operating so close together.

Day 1
After switching 40m on at 6am and trying for about 40 minutes I managed to work 9Y4LAS in Trinidad and Tobago. This was the very first call for the new call GB4FL.

40 metres continued steady all day and ended at midnight with a call into Canada and 316 contacts made.

Day 2
No time for sleeping with Simon on site and the station was online at 0700 and worked almost endlessly until 2300 UTC attained approximately 540 contacts.

Reports were favourable and glowing comments of fantisimo audio, plus 60db and you are the loudest and strongest signal on the band.

GB4FCL did extremeley well and i think this is down to team working.

There certainly was some team working going on with operator and loggist rotation and backoffice support providing delivered meals and hot drinks.

The Site

I think it is a great shame we cannot operate from the head but the red tape and time limitations makes this so difficult. The application to use theland alone is 14 pages and East Yorkshire Council rumoured about applying an annual fee of £300.

It was not an easy decision to move to World farm but after I explained to the lighthouse station event organisers they were adamant that they would rather have us participate than not.

The farmer was very accomodating and supplied mains hookup to us . We had a dedicated area that did not interfere with other campers. He even told new arrivals what we were doing and and generated some interest for us and we received a few visits inside the shack during peak pile up conditions. They left enlighted.

I was too busy to take any photos but the stations looked the part and certainly promoted the club and Lighthouse weekend very well.

A very well done and thank you to all those participating

The Perseids Meteor Shower has started and it is already obvious that there are a few Perseid meteors around. This gets VHF operators all excitable because when the shower peaks meteor scatter can be a very effective means of communication indeed. It is quite entertaining as well especially on 2m where the traditional VHF free for all takes place at the peak of of the major meteor showers.

The 2013 peak is due to occur between 18:00 UTC and 21:00 UTC on Monday 12th August. The Zenithal Hourly Rate  of the Perseids is 100, which means that given a clear sky an observer should see 100 meteor trails in an hour. In my experience when the Perseids peak it is always cloudy! The best visual display that I ever saw was the Leonids meteor storm on 17th November 1999. In the short drive from up the M1 Barnsley to Wakefield I counted over 40 bright meteors. It really was incredible. At that time the club had a battered and broken 14 element MET yagi and a barefoot Yaesu FT736. I worked 110 stations and literally heard F/G8MBI and 9A1CCY continuously at S9 for over 7 hours. It was truly amazing.

Here is some video footage from 2001 which was no where near as good. I remember the meteors burning up low to the horizon and being quite green in colour.

First a bit of background for newcomers or people who have never even realised that Meteor Scatter was viable for them, rather than re-invent the wheel I will direct you to an excellent explanation of the ‘science’ behind what meteor scatter is and how it works.

Just follow the link below

G3WZT’s Meteor Scatter Page

The G3WZT page is biased slightly towards 144 MHz operation which is very popular in Europe. However MS reflections on 50 MHz and 70 MHz are typically stronger and longer. Successful QSOs can be made with very modest equipment indeed, even if you don’t feel ready to make QSOs it is definitely worth a listen. You can also listen to meteor scatter on a simple car stereo. Find a clear frequency (I use 87.5 MHz) and just listen late evening or early morning, you will hear the meteor bursts coming through from various parts of Europe.

Meteor bursts will be mainly short but many can be over 10 seconds for instance I heard a 20 second burst from a station on 4m on Saturday.

  • During the GJ4NOK operation we worked a station running 10W to an indoor dipole at 800 kms on Meteor Scatter.
  • I have worked a station in Belarus who was running 10W to a 4 ele at the peak of the Perseids shower on 144 MHz – I was using a 9 ele and 100W.
  • In recent months I have worked many stations on 4m with just 16W to a 6 ele on 4m

Because of the short nature of meteor reflections high speed data methods are regularly employed nowadays, by far the most popular of which is FSK441 mode. This can be accessed by using the excellent WSJT software from Joe Taylor W1JT. FSK441 allows the exchange of both calls and a report in a short time, this is obviously variable depending on the length of the call-signs used but in my experience both calls and a report are available in less than 0.2 seconds with a clean decode. It works very well indeed.

Have a look here:

WSJT Software

This is what we used at GJ4NOK for the MS QSOs. As there was no Sporadic E propagation FSK441 accounted for 50% of the contacts we had.

If there is sufficient interest I will set up a demo of meteor scatter using 6 and 4m using FSK441 on Thursday night.

If you are interested just leave a comment below.

I have been looking at the results for the RSGB VHF National Field Day contest and GJ4NOK was the best DX on 4m for a number of stations in the contest. I think that it has certainly helped put the club on the VHF map.

Have a look for yourselves, scroll down to the 70 MHz section.

RSGB VHF NFD claimed scores

Thanks again to Gabi HA1YA and Roger at the DX shop.

The club now has a chain saw and we need to do a bit of tree lobbing weather pending.

Mick Simon Conrad and myself will be there this Saturday weather pending.

The biggest evolution will be the row of trees adjacent to the garage.
Whilst retaining their frontage we need to cut the back to give us about 6 metres of turning radius ready for moving dualbander , 4 metre monobander and 2 metre to this tower.

We cant do any antenna work until we have this cleared.

Anyone is welcome
