I use lithium iron phosphate (LiFePO 4) batteries for my Summit On The Air Activations, any any time I’m operating portable really with my Yaesu FT-817 or FT-897D. They give reliable power for a long period of time and crucially for me – don’t tend to explode as much as LiPo batteries! (search youtube for ‘LiPo explosion’ !)
They do however need a special charger – you cant just plug these into the charger you use for you NiMh AA’s. Unfortunately there are a lot of options for chargers out there, the majority of which on ebay etc. seem to be clones. Now I don’t mind buying clones of some products, but for things that are liable to lead to a fire if they fail I’d rather stick to branded originals. And the charger that I was advised to get and I’m still happy with is the SKYRC iMAX B6.

Another SOTA catchup post from last year!
For the 40m counties contest in May I decided to go up Tonlagee. There is a steep but short route up to it from the ESB car park and since the weather was nice I decided to stay overnight. Weather for the contest was good, but the propagation was terrible especially for a low power station, still an enjoyable afternoon up there chatting to people who came over.
What really makes camping in the wilds of Wicklow worthwhile, apart from the silence, darkness, remoteness, lack of people all night, general solitude (can you tell that I used to really enjoy heading to the hills for a few days?) – is the mornings. Here are some photos:

I did my first SOTA activation on Lug in September for the 2m/70cm IRTS contest. I won the 2m contest and did well in the 70cm considering I just had a Baofeng handheld.
However Lug is windy. It’s the highest summit in the East of Ireland and it was a particularly windy and occasionally wet day. So not the time to try and get a 10 element antenna working portable. After it blew down hard a couple of times, I settled for setting it up couple of meters above the ground and was only just about able to turn it in the wind. Worth experimenting with again, but in better weather.

It’s taken a while but I’ve finally managed to activate my nearest SOTA summit! Two Rock Mountain is the highest of the three SOTA summits in County Dublin, at only 536m. Nearby is Three Rock Mountain which has great views over Dublin City and a transmitter site near the summit transmits most FM radio and TV to Dublin. Continue reading Two Rock Activation
Kippure is one of the more popular SOTA summits in Wicklow. Probably because it has a nice road going up to it! The gate at the main road is usually closed – access is only for crews working on the transmitters, but there is parking for a few cars at the gate. This being on one of the main roads from Dublin you should not leave valuables in your car – I’d even suggest removing the boot cover and leaving the glove box open as there have been a spate of car break in’s this summer in the hills.

After passing my Class B Amateur Radio licence last year I intended to learn Morse Code in order to get the Class A license, and a “two letter” callsign. The morse requirement for a Class A license is to be able to rend and receive a paragraph of plain english text, sets of numbers, and a set of special characters and pro-signs, at at least 5 words per minute. I passed the exam in February, though I would advise finding out the structure of the exam in advance – I didn’t know what special characters were on the exam until the day or two before and had to hastily learn them!

Last Monday I had a meting at the Wicklow Mountains National Park office, and with Trooperstown so close I thought it would be a shame not to go up and do an activation. It’s a 4point summit, EI/IE-035.
Coillte provide a car park just before the bridge over the Inchavore River (T 160 970), but if you are feeling lazy you can drive up the forest road and park where the trail up Trooperstown starts (T 164 962). I found the forest road fine in my wifes Ford Fiesta, there is parking for a couple of small cars at the trailhead. Continue reading Trooperstown SOTA Activation
While in Mayo last week I decided I’d take a few hours to try a SOTA activation. There are plenty of summits to choose from, 8 around Achill and another 25 between the Nephin range and Ceide Fields. Robert Lloyd Praeger in 1937 wrote that “the Nephinbeg range of mountains is I think the very loneliest place in this country” and so it’s no surprise that many of the SOTA summits here remain unactivated. Slieve Carr, the highest mountain in the Nephin range, is about 14km from the nearest road and is surrounded by bog. An activation would probably require an overnight camp, but you would be camping in Irelands first Dark Sky Park so the view of the un-light-polluted cosmos alone would be worth it. All that though is part of the allure of these mountains. If you do feel the call of wild Mayo and want some help or perhaps a guide, get in touch with the nice folks at www.terrafirmaireland.com.

The Yaesu FT-817ND is advertised as “the world’s first self-contained, battery-powered, Multi-mode Portable Transceiver covering the HF, VHF, and UHF bands.” Although it can only put out a maximum of 5W it is very popular, particularly for Summit On The Air type activity.

Oh dear. It’s been over a couple of years since I’ve posted here!
Well to start up again here’s todays lunchtime project – a 6m antenna based on the design at http://www.dxzone.com/cgi-bin/dir/jump2.cgi?ID=13156
Thanks to Keith for all the bits of wire!
