From George Smart's Wiki
Welcome to George Smart's Homepage!
Hello and welcome to George Smart's space on the Internet. This site documents many of my projects in the form of articles.
The site navigation is a little confusing and for that I apologise. I can't find a nice way to make the page navigable; the search box in the top right may help. None of the URLs have changed, and no Wiki managed pages ever get deleted -- they are all here somewhere!
If you spot any dead links or problems with the site, then please do Contact Me. I have limited time and so don't always check things as thoroughly as I should!
So I've decided to have a blog-style few entries on the homepage of the website. I'll see how up to date I can keep this. Given that the page used to change every year or so!
Tuesday, 30 December 2014. Another batch of QSL cards arrived for M1GEO, MQ1GEO and MO1GEO this morning in the post. I had unfortunately run out so I have ordered another batch. They will take a week or so to arrive. I'll get them out as soon as I can. I also ordered another batch for GB0SNB too, while I was at it!
Tuesday, 23 December 2014. Today I finished my 4 month stint at ARM Ltd. During my time I haven't done much with the website, but I have been working on my implentation of a fully KISS compliant Arduino TNC as well as using DSD 1.7 to decode digital modulation such as D-STAR and DMR (and others) using my FunCube and RTL-SDR receivers.
Saturday, 11 October 2014. Purchased an Icom ID-5100 and fitted inside the car.
Tuesday, 23 September 2014. I have made a few changes to the mail server configurations for the domains I host. I was receiving around 100 spam emails per day, because I was worried about missing mail. Under these new settings everything seems fine still, but just in case you email and get no reply...
Monday, 8 September 2014. Today I started an internship at ARM Holdings for 4 months so my regular activities will be somewhat interspersed for the foreseeable short-term future. Lets see what the next few months have in store for me!
Sunday, 20 July 2014. Took the 14 MHz home-brew beam (right) out this weekend for LEFARS annual field day at Alymers Farm. Conditions were not so great, but we managed to work some nice DX including VK6, plenty of North America and Canada, and several more rare locations.
Thursday, 10 July 2014. Ordered a 144 MHz Anglian Transverter from Sam, G4DDK, as well as a DEM L144LNACK-2N low noise preamp for 144 MHz. I am very short of time of late, but it is my intention to experiment with some EME operation this summer and winter, so I figured I had better start buying...
28 June -- 2 July 2014. Drove to the Ham Radio Friedrichshafen International Exhibition for the second time, this time leaving a few days each side to recover from the long drive. In the first spare day we drove into Italy (right), stopping in Liechtenstein (to say we had been). Going, we drove over the Alps (left) and returned back via the tunnels through the Alps (as it was dark). Utterly amazing drive!
Tuesday, 10 June 2014. Working late from Monday evening till Tuesday morning to get some of the Contiki timer issues fixed. I think I have corrected a bug with the Contiki rtimer code for the TelosB mote, but that remains to be seen. The code functions great in the simulator with the modded timer library, but still doesn't work on hardware.
Sunday, 8 June 2014. Over the weekend I worked on my 1.25 kW solid state PA based on F1JRD's design from Dubus. I bought the kit at the Friedrichshafen Hamfest last year and built it up late 2013 but due to problems, I never had more than around 40W output. This weekend, with a new set of capacitors from ATC I rebuilt the output matching and fired it up once again. With my 1kW/50V power-supply I can get around 600W output, which his more than enough. This is still a work in progress, but things are moving forward with the project. Design information here.
