Some Radio Antics

Shack activity has been curtailed with the antenna 'mast' spending a lot of time luffed over due of the winter storms and high winds that have battered the UK over recent weeks.

Thankfully things calmed down and was able to put the antenna back up but I seemed a little deaf on VHF/UHF dropping several S-points on local repeaters and then started to see high VSWR readings. The incessant rain had somehow got into the connector under the collinear despite being generously wrapped in self amalgamating tape. I replaced the connector and removed a couple of feet of coax in case any had seeped into the cable.

Like much of the UK amateur community I have been trying to listen in to British Astronaut Major Tim Peake during a number of ARISS UK school contacts during the Principia mission on the International Space Station. It is pleasing to see the enthusiasm, interest and publicity it has generated for the hobby.

There is another contact tomorrow (Friday 26th February 2016 at 1440UTC) with the City of Norwich School. While reception of the first two contacts proved a little disappointing for me, the one last week was much better and I made a video during the pass.


The Astronauts are certainly busy on the space station and there was an ARISS contact this morning with an Italian school. It was a low pass here only reaching 7 degrees above the horizon but was pleased to capture Tim Kopra conversing. I was using just the X-50 collinear on the FT857-D


The repaired ATU and a new balun on the OCFD has made a big difference to HF. It is much less noisy and I am now able to match the antenna to 80m something I could never do before. While it will be very inefficient on such a short antenna I did run a little over 2W last night on WSPR as a test, and was pleasantly surprised.


I have also been doing some JT65 and for the first time some JT9 inspired by a demonstration at SKARS and I was pleased to make a JT9 QSO with JA5BDZ on 15m using 10W.

A big help to HF has been tracking down the source of my recent QRM, which wasn't as many suggested my evil PLT devices but in fact the now redundant wireless router. While the WiFi was switched off it was still being used as a network switch and for some reason had suddenly become RF noisy, it wasn't the switching PSU but the actual unit and would happen a few hours after being switched on. Funny thing it is not the first time I've had an access point suddenly emit QRM.

A couple of weeks ago I went out with Stewart (M0SDM) to assist him flying his kite antenna and we operated under the club callsign MX0SKR, for a couple of hours, it was great fun.




Last weekend I also helped my brother David (M6GTD) install a couple of antennas at the family home. He can finally use the radio he brought at the Hamfest back in September, a Diamond X-50 dual band collinear and a home brewed 33ft long OCFD should get him on the air! 


David helped me at the Hamfest with the balloon launch


My apologies if this blog post sounds like a bit like an excited child recanting his holiday "I did this, and then I did this and I also did that" I hope to post something a little more coherent and structured soon!

Radio antics on the Inner Hebrides

I have just returned from a much needed break away to the Inner Hebrides of Scotland, consisting of a week on the Isle of Skye and then a week on Islay.

It was our fourth visit to Skye but Islay was a new destination for us. While it was primarily a holiday away with the wife and dogs doing some walking, sight-seeing, visiting the numerous malt whisky distilleries (especially on Islay and Jura) I also planned to do some operating.

Last year I did operate from the same rented cottage on Skye but this year I wanted to do some portable working on both islands. With this in mind and following my disappointment last month I had taken time to properly prepare. As well as repairing the end-fed wire "magitenna" that had caused issues last time out I had constructed a linked dipole for 40m/20m for a simple inverted-vee using a fibreglass windsock pole.

I took the Yaesu FT857-D with a small SLA battery for portable work and a small power supply when in the cottages. Unfortunately things didn't get off to a good start when I dropped the battery when unpacking. I had used a small screw-terminal chock block to connect to the power loom and the weight of the battery simply ripped both wires out of the terminal block and they touched with an almighty spark and welded themselves together. I acted quickly to remove them from the battery but it has almost certainly affected the battery. Despite this set back the battery performance proved more than sufficient for my needs.

During the first week on Skye, the South Kesteven ARS, which I am the chairman, had their monthly meeting and we planned to try and make a scheduled contact (sked) I did have a run through one evening to test the set up and antenna, drinking a beer and making contacts while sitting on a bench at the cottage watching the sunset going down over Loch Bay with the Outer Hebrides in the distance - sheer bliss!



On the night of the sked the famous Scottish midges were out in abundance and I opted to work from inside the cottage. A successful contact and conversation was made even if there were a few issues at the club that night. They were unable to get the planned antenna up due to activities in the nearby scout hut but like all good hams they improvised using an Ampro-40 magmounted vertical on top of a large saucepan until they were able to get a dipole up but by then band conditions had started deteriorating, but a contact is a contact.

Going portable I had planned to do some Worked All Britain Award activations, the W.A.B scheme uses the Ordnance Survey (OS) mapping agencies National Grid Reference (NGR) system to divide the country into 10km x 10km grid squares. The aim is for activators to operate from the squares and for other operators to “work” those squares.

In addition to activating squares, operators can also activate pillar type triangulation points (commonly known as 'Trig Points') which were originally used to carry out the surveying for Ordnance Survey maps but have now been abandoned and have become interesting relics and many are now sadly falling into disrepair, however many people still seek them out and a database exists at www.trigpointing.uk

I planned to try to activate some squares and trig points as the more remote locations such as the Scottish Islands are highly sort after as they don’t get activated as often.

Firstly before I describe my adventures let me be brutally honest! I am fat, in fact very fat and unfit!

I haven’t always in such poor shape, in fact I used to be a keen walker regularly going out at weekends walking miles and even completed several long distance footpaths, including The Coast to Coast Walk back in 1991. I then spent many years competing in dog agility most weekends which kept me reasonably fit but the last few years circumstances have changed and I now have a sedentary lifestyle and desk bound job. This coupled with stress, apathy and being a more than willing victim of comfort eating mean I have piled on the pounds.

Why make this confession? Simply because most trig points are on prominent hill tops and high ground throughout the country and therefore will require some physical climbing to get to them. I was under no illusion there were many on Skye and Islay that I stood no chance of reaching without some form of coronary episode! But I had identified a number of more attainable ones requiring on paper just a modest exertion.

How wrong I was.. 

On the Isle of Skye we were staying on the Waternish peninsular and I had identified two possible candidates the nearby Ben Horneval (TP1275) and Ben Geary (TP1269) while both were over 260 meters in height the maps and descriptions seemed to indicate reasonable but still strenuous approaches. However prior to us arriving the weather had been very wet and the ground was very boggy and when actually standing looking up at the hills I sensibly thought "Not a chance!"

Instead I opted to go to the coast, specifically Talisker Bay which is glorious and simply activate a WAB square NG33 while the wife and dogs occupied themselves on the beach. So off we went, drove across Skye and walked the mile or so from the parking area carrying the rucksack with radio and pole. I went of to a nice spot just up of the beach to set up to then discover I had forgotten to pack the coax... never mind had a good few hours on the beach and stopped off at the Talisker distillery on the way back.


I hadn't given up on a Skye trig-point and I had spotted Culnaknock (TP0664) on the North East coast of Skye, which was tantalisingly described as “one your granny could do” and had the advantage of also having a Geocache for the wife to get. So we set off in the car with the dogs for a grand tour round the island and ended up there late one afternoon.

There were a number of suggested approaches, on the first we were met with fences, livestock and a sign saying private and seeing no obvious path up we investigated another through a gate on the main road. This was more straightforward however the nearest parking area was a little way down from the gate. The road was extremely busy and we weren’t comfortable trying to walk up the road with the dogs due to the traffic. I was feeling at little peeved at this point and opted to stay with the car while the wife retrieved the cache and took a photo so I know what I missed.


In the end I made no trig point activations on the Isle of Skye, but should we go back at least I am more prepared.

The second week of our holiday was on Islay. Islay is simply a fantastic place to visit, much quieter than Skye, probably due to the two hour ferry journey involved and I did manage some portable operating between visiting the eight whisky distilleries and a trip to a ninth on nearby Jura.

The cottage we were staying in overlooked Lagavulin Bay with the Lagavulin Distillery and the remains of Dunyvaig Castle, it was a two minute walk to a high point near the ruins where I set up one evening and had an hour operating in the setting sun, again band conditions were poor but I didn't care, NR44 was activated.




There were two trig-points quite near to the cottage. Ardmore Point (TP0875), from the map this looked simple enough, however the road to Ardmore was a private road so couldn’t take the car and while walking there from the nearest parking space was simple enough time didn’t allow it.

Cnoc Rhaonastil (TP2293) was another potential trig point, locally called the Fairy Hill it promised spectacular views for short but steep walk, however again parking and access proved problematic and so was never attempted. 

The Mull of Oa (TP4976) trig-point I actually walked to being next to the American Monument which commemorates the loss of two troop ships in 1918, the Tuscania and the Otranto and the spectacular location overlooks the very spot where the Tuscania sunk. The monument built to thank the inhabitants of Islay for their help is built in the shape of a lighthouse and is visible from many areas on Islay. Despite the very wet ground conditions the walk was straightforward however the weather put paid to any attempt at activating. The wind was very very strong, as this short video demonstrates.


The attempt on An Curran (TP0839) really was a comedy of errors, being a fairly modest 49m high and close to where we were staying it should have been straightforward. To get to the summit you have to navigate a dense conifer forest and I had read the description on the trigpointing.uk website of how to ascend via a gate and distinct path.

It looked short and simple so didn't take a map or the GPS with me. I found a gate and what seemed like a path along a wall and set off and quickly the path became indistinct and the trees were indeed very dense, so dense I was struggling to get through them. But I carried on going up gaining altitude thinking I must be nearing the top, however it got to the point I just couldn’t get through the trees anymore and there was no sign of them thinning out as they supposedly did at the summit. It started raining and was having to negotiate water filled hollows, heather and bracken hummocks and swarms of midges - this was not fun!

Eventually I did spot a clearing only to find it was where a power line ran up the hillside. I knew I was too far south and since going north through the forest was neigh on impossible I instead descended following the power line through chest high bracken back to the road, all the time worrying about "Serpents" as the locals quaintly called the adders which were prevalent this year.  When I did reach the road I had to climb a low dry stone wall and promptly slipped into a deep water filled ditch on the other side, losing a boot in the peaty mud much to the amusement of a passing group of horse riders.


I almost decided that this was enough, I was doomed not to activate a trig point however one remained on the hit list and I succeeded in activating it on the final day.

I had spotted Cnoc Lolairean (TP2283) when visiting the nearby Bruichladdich Distillery earlier in the week, only 29 meters high it was on a small ridge along the side of Loch Indaal and it involved just a short walk up a farm track and up a narrow track to the top.

The wife went of to get a coffee from the nearby mini-market and took the dogs for a walk on the nearby beach while I went to the trig point. What it lacked in height it made up for with the position with fantastic view across to Bowmore and down the Loch.

I used bungee cords to hold the pole to the pillar and soon had the inverted-vee up on 40m. I had around 40 minutes of operating, and band conditions were again poor with lots of noise but I did make a decent number of contacts running approximately 20W before the battery voltage started to drop off. I was especially pleased to work Stewart M0SDM a fellow SKARS member.




One unexpected radio highlight on Islay was capturing a SSTV image broadcast by the Russians from the International Space Station to celebrate 40 years since the Apollo-Soyuz link up. I didn't know about the SSTV operation before we went on holiday and so hadn't taken any VHF aerials with me so I just stuck a piece of wire into the back of the FT857-D and dangled it out the window to hopefully catch one of the passes early on the Sunday morning, I hadn't had time to unpack properly but the captured image was actually quite good considering.

LHS Episode #150: The Sesquicentennial

150th-birthdayWell, folks, it's hard to put a description on this episode. We talk about our usual range of topics, but there is so much more thrown in that we can't even begin to enumerate it all. One thing that can be said, however, is that this episode was FUN. We hope you enjoy it all the way to the end. Apologies for the first 20 minutes or so of Pete's microphone audio. We promise, it does get better. THANK YOU for being a listener. We do this all for you.

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!
