MADHEN Eggsplorer-1 FOUND!

The payload for the MADHEN Eggsplorer-1 High Altitude Balloon that I and the SKARS team launched in June has been located washed up on a beach in the Netherlands. Amazingly the egg was still intact inside the capsule.


On Friday evening I went to the Hucknall Rolls Royce ARC to give a presentation of HAB flights including details of the Eggsplorer-1 launch and its subsequent apparent loss at sea, then yesterday we had a trip to North Yorkshire and visited the Boon Hill Show and I admired the display of eggs within the produce tent.


It must have been synchronicity since a few hours later despite the poor mobile phone coverage I spotted a message on my mobile phone. It was from Jan Wouter Kramer from the Netherlands, whilst out on a remote beach in Terschelling he had found the Eggsplorer-1 washed up and taken some photographs!

Nearly six weeks to the day after launch she had been found with the egg apparently intact! I tried several times to ring back but the poor mobile coverage prevented it so sent a text message hoping it would reach him. I couldn't wait to get home to and finally did just before midnight.

I frantically logged on to check emails
Hey Andrew

Found your email on the site.
These are the pics we made.

We found it today about 14:00 during a walk on the beach of Terschelling in an area were not many people are walking because it's more than a two hours walk from the nearest houses.

As you can see the egg wasn't damaged but had probably lost it's strength. While trying to investigate what was inside the 'bulb' it broke open and the egg broke in two parts. It was nearly empty. Only a few cc of dark 'water' was left in it with a terrible smell .......

Best Regards !

Jan Wouter Kramer
The pictures were amazing






I emailed Jan back as far too late in the night to telephone
Hi Jan, 
Sorry I was able to take your call this afternoon but was out of coverage for most of the day.

Thank you very much for the information and pictures of the Eggsplorer-1. It was our first ever balloon flight and after it landed in the sea I thought we would never see it again.
Amazingly it appears very much intact, shame about the egg being rancid, would really have liked to get it back and would have paid for shipping - but I can imagine the smell was awful.
The Raspberry PI circuit board inside the box had a SD memory card which was held down with gaffa tape, I am not sure if it is still attached and it may have contained some photos of the flight taken with the onboard camera. However given the remoteness of the payload I understand if it is too far to return for such a slim chance.

As I wrote given the remoteness and the rancid condition of the egg I couldn't really expect Jan to go out again to collect it but had a fantastic text message this morning
Hi Andrew, thanks for your email. The good news is that I found the local police willing to pick up the remains of the eggsplorer. (They are allowed to drive on the beach by 4x4) I just got a phonecall that they found it and are willing to send it back to you.
So you have an address for me ??
Best regards
Jan Wouter
As you can imagine I am totally EGGSTATIC!!

I rang Jan this morning and had a great conversation, seems he visits here every year and goes beach-combing with his son, they have never found anything quite as exciting as this!


So MADHEN Eggsplorer-1 has traveled 31km into the stratosphere, landed in the sea and traveled approximately 370km from launch site to its final resting place on the beach. The World Egg Throwing Championship people are very eggcited.

Just hoping that there are some photos on the card if it has survived, cannot be sure from Jan's photographs. Since the flight I have suspected two possible fault scenarios, bad connector on the SD card on the Raspberry Pi or the antenna was broken off due to the backup tracker suspended underneath. I am hoping it was the latter and the card is recoverable and readable since it would contain pictures.

The backup tracker is also there but has lost its polystyrene egg cover, gps-antenna and battery pack but can see it is still attached to the main payload. The question is how long it has been on the beach? Given the relatively good condition of the box and the labels are still attached it may have been quite soon after splash down.

I am indebted to Jan for taking the trouble of contacting me and the police, I can't thank him enough! When I get the payload back I will post an update.

All the members of SKARS are eggcited and gives new impetus for the National Hamfest flight next month.

National Hamfest Balloon Launch

Following my maiden high altitude balloon launch last month of MADHEN Eggsplorer-1 at the World Egg Throwing Championships I have agreed to attempt another launch at this years National Hamfest which takes place on the 25th-26th of September at the Newark Showground.


Once again I will be assisted by the members of South Kesteven ARS and hopefully this time it won't end up splashing down and being lost at sea.

I intend to have a SSDV system running on a Raspberry Pi using the usual UKHAS RTTY protocol and possibly this time a LoRA transmitter which allows faster transmission and higher resolution, however this requires ground stations to use a LoRA receiver, this are straightforward to build. I have done some experiments with the code base developed by Dave Akerman but didn't implement them in the Eggsplorer-1

As to any special payload? Well following the yokes about "Ham n Eggs" following the sending of an egg in the stratosphere, who knows....?


Anyone interested in joining South Kesteven ARS and being involved then contact me via the club website at www.skars.co.uk or our facebook page

First HAB flights were a success

Two years after discovering the hobby of High Altitude Ballooning I have migrated from being just a passive tracker and finally completed my first flights assisted by other members of the South Kesteven ARS.
Ready to launch
Back in March I posted about the opportunity I had to make a launch at this years Swaton Vintage Day and the 10th World Egg Throwing Championship

South Kesteven ARS were going to hold a special event station with the call sign GB2EGG. During the planning stage I jokingly suggested throwing an egg in to space on board a balloon, I shouldn't have yoked...

The whole venture captured everyone's imagination, sadly putting the special event station in the shade but we certainly got a lot of publicity for the club and amateur radio in general.

Featured on front page of local paper

There was certainly a lot to learn and get organised, not only did I have to design and build the flight computer which was the easy part but I had to build the payload containers get the balloon, parachute, cord the lifting gas (Helium) and build a filler assembly as well as getting official permission from the CAA for the launch.

The information on the UKHAS wiki as well as Dave Akerman's High Altitude Ballooning, From The Ground Up (and back again) were invaluable.

The cost of this venture was not insubstantial and thankfully MADHEN - The Ultimate Party Band agreed to sponsor the flight which helped greatly and I received a nice donation from fellow club member Mark Orbell (M0OBL)

Months of work and lots of last minute hitches but I was ready.

Two flights were planned an altitude 'burst' flight with a raw egg payload with a parachute decent. The main tracker MADHEN would broadcast SSDV images and telemetry with a telemetry backup tracker EGG1 suspended below it.  The second flight was a foil party balloon 'floater' with a tracker kindly donated by Steve Smith G0TDJ of ProjectAVR

Both flights flew and were a great success, unfortunately the SSDV tracker failed early in the flight so no in flight images were received.

The main payload is pictured below before the flight resting on its side. The Styrofoam box contained the flight computer and radio transmitter with a camera attached to the Raspberry Pi and the "flying saucer" model which contained the egg was positioned to be visible.
 

As this test image shows the 'egg saucer' should have had the earth below it.


However the arduino based backup tracker which was suspended below it worked perfectly.

There were some issues with getting CAA approval because the sky was very busy on the day including the last remaining Vulcan Bomber VH-558 making its farewell flight in the area, cue jokes about the Vulcan getting scrambled... but approval was given for a morning flight, not ideal for the organisers but we were still a spectacle for the handful who were there early.

Starting the fill

Checking the neck lift, made difficult by the wind

Stewart (M0SDM) helping me tie off the balloon and payload cord
The strong gusty wind made launch difficult
Me and Stewart making a dash to assist the launch
Someone was on hand to capture it on video for The World Egg Throwing Federation


It started so well,  I was receiving telemetry and image packets and then transmission stopped


However as I said the other tracker worked brilliantly and this was the final flight path as visualised in Google Earth. The ascent and decent rate and the burst altitude were exactly as planned and predicted, so I know I got the neck lift measurement right even with the high wind on the day.

Path of MADHEN/EGG1

A splashdown at sea was inevitable due to the wind conditions, hopefully it it survived the landing it may wash up on a beach somewhere and we can retrieve the images.

With what little Helium remained I was able to lightly fill and launch a foil party balloon carrying a blown egg shell as a 'floater' which made a valiant attempt to reach the continent at 6-7km high travelling at 120+km/hr where it reportably hit bad weather and was downed.

 All in all an eggscellent day!

April Radio Antics

It has been an extremely busy month since my last post, sadly not all of it radio related.

During the Easter holiday I was away in the caravan at a dog agility show in North Yorkshire, camping in the grounds of Duncombe Park just outside Helmsley. When not competing I was able to find some time to operate.

Boris combining both hobbies!

Using just an M0CVO Magitenna I had some reasonable low power SSB operation on a number of bands and activated a square for the Worked All Britain Award (WAB) (SE58) and gave some points away during the Polish SP DX Contest.

The WAB scheme was something I signed up for last year when I went to Skye but haven't participated till now. The WAB net on 7.160MHz is a little daunting to listen too but once I jumped in it was relatively painless to activate the square and I plan to do some more when I go back to the Isle of Skye and Islay later this year, but I must improve my portable HF antenna.

Over the weekend of the 11/12th April there was another SSTV activation from the ISS in celebration of Yuri Gargarin's life. I had some good results decoding images and decided that I'd use it as a way to promote South Kesteven ARS locally and contacted the local newspaper.

The Newark Advertiser did indeed feature the story both in print and on their website and they were very good in mentioning the radio society. It was also printed in the sister free paper.

It was nice to get some very complimentary reaction to my publicity drive in social media and other websites including an article on the Amsat-UK page http://amsat-uk.org/2015/04/15/iss-sstv-in-the-press/



Last weekend I and other members of the South Kesteven Amateur Radio Society operated the special event station GB5ROC at the Buckminster Cold War Royal Observer Corps (ROC) Nuclear Bunker Open Day.

Situated on the Lincolnshire/Leicestershire border ROC Post Number 62 is leased to the UP AN’ AT EM! History project and has been restored as a museum and is managed by ​​​Jed Jaggard. The free open day was a rare chance to visit and experience an important part of British post-war history.

These bunkers are underground structures found all over the United Kingdom, constructed as a result of the Corps’ civil defence nuclear reporting role and were operated by volunteers during the Cold War between 1955 and 1991. There was a network of over 1500 such monitoring posts around the UK designed to detect nuclear detonations and monitor blast and subsequent fallout and radiation levels should an attack take place.

Thankfully they were never used and the last of the posts were closed in 1991 when the majority of the ROC was stood down following the break-up of the Communist Bloc. Many have been demolished, fill in or adapted to other uses but the majority still exist, although in a derelict condition.

During the open day visitors had the chance to climb down into the bunker so for reasons of practicality SKARS operated GB5ROC from a tent close to the bunker hatch.



Along with Stewart Mason (M0SDM) and Sean Burton (2E0ENN) we operated on 40m from 10:00 till 16:30 BST and made a total of 151 contacts mostly UK operators with a number of European stations.

Equipment was supplied by Stewart who did the majority of the operating and consisted of a Yaesu FT-897D at 100W feeding an off centre fed dipole at around 30ft on top of a Racal push up mast. Stewart also provided a new club banner.

The open day was very well attended and a number of local and not so local amateurs (one visitor from Australia VK4UA ) came along thanks to the publicity the event had received on Facebook, Twitter, GB2RS and the Southgate ARC newsfeed. It was great to meet up and chat.

Encouragingly members of the general public were keen to learn what amateur radio was all about and they were able to take away a number of leaflets with information about the hobby and contact details for SKARS.




It was an excellent day all round with the operators have a fun time and gaining useful experience of operating a pile-up. The weather was kind with blue skies and sunshine. Hopefully it will become a regular activation at future bunker activations.

The video below Stewart operating Richard M6GPT who had tried most of the day to make contact and was successful just before the station was closed down.



SKARS member Mark (M0OBL) had monitored GB5ROC and made a video of his Elecraft K2 receiving us load and clear.



Next month is going to be very busy as I have GB2EGG and the Eggsplorer-1 HAB flight to organise and that too has made the press. http://www.sleafordtarget.co.uk/Egg-sent-space-World-Egg-Throwing-Championships/story-26372439-detail/story.html

Oh and lastly remember this is the original "Radio Antics" blog, often imitated but never bettered.. 73

Update, the visit of VK4UA to GB5ROC wasn't due to any publicity or advertising - it was simply because Stewart had his van parked on the verge with his callsign clearly visible and he was visiting the area - the simplest ideas are the best it seems!
