1w into Hustler 6-BTV

Whilst some might say that lifes too short for QRP. Newly licenced hams take note. 1w into a lossy vertical in a bad location doesn’t mean you’re stuck with QSO’s as far as the end of the street.

All this was achieved with a modest transceiver (IC-7000) and a modest antenna (Hustler 6-BTV with a few radials). The lesson here is that DX isn’t just for those with limitless pockets of cash, elevated QTH’s and antenna systems that can rival your nearest broadcaster. You just might not be talking to the other station!

Seriously the design is taken from any of your favourite calculators. I have found that they vary slightly against the original maths but I know my Sotabeam works very well so that’s a good starting point for dimensions.

Costs to date are in the region of a few quid but by far the most expensive parts are the nylon bolts used to hold the elements. I’ve bought a bunch so I’ll have a few attempts at drilling straight through the nylon without heating it up too much.

My FT817 lives in a padded bag when its not in use along with its charger and an old Miracle whip. Now the Miracle whip no longer has a whip courtesy of my youngest who managed to snap it in half. Whilst it isn’t the finest antenna it was extremely useful for travelling. Now I need a replacement telescopic whip and I’m guessing they’re either hard to get hold of or unnecessarily expensive.

The other doom was the CI-V controller (mine is a G4ZLP USB digimater pro+) which has given some sterling service over the last couple of years but now has decided to read the frequency but not PTT or supply audio. Several wasted hours later the status quo remains. Reliability of kit in my shack isn’t that great at the best of times and this just confirms that a law based on expense and reliability. ‘No matter what it costs the chances are that it’ll stop working for no apparent reason’.

At this rate I’ll have nothing left either as a result of a 3 year old or its own suicidal components..

You may remember that a while ago I bought a 2 element lightweight 50Mhz antenna that is currently sitting in a 95% completion state so that will need a bit of finishing off and talking about.

I also purchased a Prowhip 5 band fishing pole antenna on a bit of a whim, partly because I was going to make one and thought I wouldn’t have the time to do it this side of the summer and partly because it was so cheap I doubt I could have got the parts and made one up myself for much cheaper. It calls itself a multiband antenna but its really a 1/4 wave vertical in a fishing rod that will tune to 40m and a few higher bands with a tuner. More on that later.

The other thing I’m involved with is helping with the Workington club (MX0WRC) to try and help out some of the novices and non home brewers to make a simple 3 element 2m band antenna out of ‘stuff from a hardware shop’. There are some well established designs that work but the focus is on getting the guy’s and girl’s to make their own.

I’ll also be helping out with the Fred Whitton Cycle Challenge with the local Raynet group shortly so weekends are looking quite busy .So as you can see, plenty on the plate but no time to get on the air. Something is going to have to stop, my vote is work but I doubt the mortgage will get paid, mores’ the pity.

Saturday had us checking the local communication paths for the various areas. It’s the first time I’ve been involved in any of this kind of thing so Paul, 2E0EET took me through the basics and now I’m looking forward to being a spectator and watching those who’ve trained for months on end to attempt this formidable ride.

It took me over 7:30 hrs when I did it do giving up the same amount of time with the rig at cockley beck (not too far from the Hardknott summit) seems a small price for my earlier enjoyment.

Welcome to the latest Raspberry Pi update from RS Components!

Much has been happening behind the scenes since you received our last update, not least the start of compliance testing on the Raspberry Pi.

Why are we doing this? Compliance testing is an essential part of bringing any electronic product to market. The Raspberry Pi is being tested to make sure it conforms to all the regulations that apply to electronic devices around the world. This means that we can be sure the Raspberry Pi we deliver to you meets the correct standards and is as safe as you would expect any electronic device you purchase to be.

We’re working with the Raspberry Pi Foundation to manage the testing process as quickly as possible, while ensuring all tests are carried out to guarantee safety. More information is being posted on the Raspberry Pi website , as well as on our own FAQ pages rswww.com or DesignSpark. We’re also regularly tweeting updates on progress. Follow @RSElectronics on twitter to catch the latest news.

Alongside this, we’ve also been contacting the first group of people who registered for a Raspberry Pi from RS, to help us plan delivery of the initial batch of boards. In next week’s update, we’ll provide more information on how we’re managing the queue and the order process.

For those who aren’t too sure what it is. WOTA is a bit like SOTA but for the Wainwright Fells in the Lake District. If you don’t know what SOTA is then one explanation is portable operations from summits (or fells if you live here in the lakes). Or as I like to describe it to non hams, working you way up a fell till you get to the top, looking at the view for a bit then getting out a radio (generally in the fog or rain, in the lake district) and saying ‘hello its me, can you hear me?’ ‘yes, it’s me, can you hear me?’ ‘yes, good stuff, who’s next’. I don’t think I’ve had too many positive looks giving that explanation but its better than trying to explain what that pole sticking out of your rucksack is in a howling gale.

Anyway,m back to the point. WOTA was devised by Julian, G4ILO and the first activations have been tabled as the 21st March 2009. So all I can say is happy birthday and my XYL wants a word with you because I’ve not managed to fix the downstairs toilet whilst I’m out operating from a fell top.

Yesterday I made a secong attempt to activate Scafell Pike. Usually I got up to summits alone or with the dog bit this time was with a bunch who were training for the 3 peak challenge. Needless to say the summit was in cloud, it snowed then hailed then rained on me as I came down. Still this time I had a whole load more qso’s and a much more satisfying activation. Wast water (in the photo) is a beautiful lake that is surrounded by some impressive fells. Not as nice a Ennerdale but then again I am a bit biased.

Anyway the blurb from the Google marketplace / Google play site indicates that the app is for all sorts of RF planning and I quote ‘DAB, DVB, GSM 2G/3G/4G/LTE, Marine VHF, PMR, TETRA, PTT, WiFi, WiMax
Groups: Emergency services (Ambulance, Coastguard, Fire, Forestry, Police), Amateur/Ham enthusiasts, Armed Forces/Military, Construction industry, Event organisers, Government, Maritime/Private Security, WISPs.’

For me its a way of simply checking the coverage I’m expecting. there are 2 applications for your Android phone and a web based offering to boot. The programme is squarely aimed at the corporate market and the trial offshoot for hams is either a 12km limited plot for free or for a fiver you get 100km of signal plotting. I guess you could reduce power to minimal levels and attempt to extrapolate but it doesn’t seem worth it if you’re into planning for a RAYNET or emergency communications type situation.

Still for the casual user there is at least something to wet your appetite and the operation couldn’t be simpler on your phone. Use the GPS or map to locate where you are / want to be. Entering in the frequency and power as well as height above ground for the rudimentary settings and press the button to calculate your plot. Other aspects can be changed such as type of ground and the usual modelling parameters that you’d expect from a simplified model that bears a similarity to Radio Mobile that Julian, G4ILO posted a while ago. I’m only guessing but I’d image its a similar if not the same engine that delivers the plots (Irregular Terrain Model).

Have a play with the trial version and see if that takes you fancy and if you dip into the paid for version then let me know what you think.

I was trying to think of a project that I could use at MX0WRC (Workington and district amateur radio club) to help give some direction to some of the members who may never have built anything other than the kit they built for their intermediate licence. So, as I’ve been roped in to give a talk on my portable set up, which consists of what I thought were low cost antennas I thought I’d found the right direction.

Low cost is not what I came across when researching simple antennas. It seemed that I was way off the mark for commercial offerings until I found a company in Germany called Nuxcom. They supply what look like simple yagi kits at realistic prices. By which I mean the cost of the materials isn’t prohibitive (For example from a raw material supplier 25mm box section can be bought for as little as £6-8 for a 1m length, enough for a 3 element 2m yagi and round tube for similar cost – and this isn’t cheap Chinese metal this is western European fully traceable materials! Don’t even get me started on the price of pipe clamps)

So, to placate my ever growing concern that prices are rising higher than a bankers bonuses, without any real justification I ordered one of the larger kits from Nuxcom, a 2 element lightweight 6m yagi. Purchasing was a bit drawn out as I placed an order and the ‘quote’ was returned with shipping costs added in a few hours later. But at £35 I was prepared to take a gamble, even is a third of the cost was shipping.

I’m expecting the kit before the weekend and I’ll do a little write up when it arrives. On the face of it the kit looks fairly simple in design without any bells and whistles, just what we need to add to the J pole, vertical and dipole designs that I plan on demonstrating.

What I’m really hoping for is a good value, simple lightweight antenna than doesn’t cost the earth so that the club members can learn and experiment without breaking the bank. More later.
