Marconi Day 2016: GB4MHS at the Oxford Museum of the History of Science

Ken, M1SLH, writes:

“Well, that’s another Marconi Day done and dusted! Working from the basement was much better I thought; much easier to see everything and get the visitors’ attention. Brian’s collection of early apparatus was obviously a big attraction, and the Morse Code hands-on was as popular as ever.

That the aerial worked at all was a great surprise to me, and thanks to Colin’s excellent installation, it stayed up on a rather windy day. In fact, it stayed up rather too well and had to be coaxed off an anti-pigeon spike with a fishing pole in the end.

Thanks to everyone who came and helped.

Construction Competition, 2014

Congratulations to Ernesto, M6ATD, on winning the 2014 Construction Competition – his second construction competition win in less than five years!  The cup was presented by last year’s winner Brian Hawes.

Tuesday evening showed that some members still have soldering irons and know how to use them! Five excellent examples were exhibited:

  • A one valve receiver, which was a reproduction of a model build in the past, by Mark
  • A reproduction of the wartime “telephone book” transceiver by Ernesto
  • Two entries from Brian, his high performance crystal set and a power amplifier for 2m.
  • A high power filter for 40m from Colin.

Ernesto won this time, and took away the cup. Perhaps we should have given him an isolating transformer as well as his project was an AC/DC design!

Marconi Day, Museum of the History of Science, 26 April 2014

Allison and I with Monty called by The Museum of the History of Science on broad street to see the Annual event Marconi Day Saturday.

The Oxford & District Amateur Radio Society had been invited by The Museum of the History of Science to celebrate the birthday of Guglielmo Marconi.

During my visit I took a few snaps you can see them at https://www.flickr.com/photos/m3jfm/sets/72157644324217551 as well as select photographs published on Facebook below:

Newbury Rally, 2013

Did you see us at the Newbury Rally on Sunday?

ODARS always puts in an appearance at Newbury with our fine collection of components, home brewed radio kit and interesting commercially made gear, either no longer wanted by members or given to us by the family of an SK. We have manuals, circuit diagrams and other information available for some of the equipment so if you bought a branded item from us and would like to know a bit more about it, please get in touch.

Club supports Wow! How?

On Saturday 10th March, ODARS organised a Special Event Station, GB4WOW, at the Oxford University Museum of Natural History. This activity supported the Wow! How? Family Science Event.

Construction Competition, 2011

Congratulations to Ernesto, M6ATD, on winning the 2011 Construction Competition. I think we all agree that his Paraset is a really superb achievement.

However, the fact that there were seven other entries, each representing a different requirement for the amateur radio user, but all showing great ingenuity and skill in their design and construction, was very welcome. As was the willingness with which the constructors came forward to explain their work in front of the other members, one of which commented that it was like having eight meetings on one night!

In no particular order, the other splendid entries were:

  • Transistor curve tracer add-on for a ‘scope by John
  • FET active antenna by Brian G2KQ
  • PIC programmer by Paul M3JFM
  • 70cm mast head pre-amp by Colin M0DDT
  • 4m transverter and power amplifier by Eddie M0AEO
  • Forward and reverse power meter by Mark G0SPS
  • Remote controlled antenna switch and auto ATU demo by Phil G7GVV

Well done and thanks to all of you. Ken, M1SLH.

SSB Field Day 2011

Taken from http://www.2e0sql.co.uk/2011/09/17/ssb-field-day-with-the-oxford-d-a-r-s/ by Peter, 2E0SQL.

I know this is a little bit late considering SSB Field day was nearly 2 weeks ago, but it’s been a busy few weeks so blogging had to take a back seat! This year I took part in SSB Field day with the Oxford & DARS, like normal from the site at Horspath which is on the edge of the city close to the BMW Mini factory.

Setup went to plan and we had the Force12 C31XR, 40/80m Dipoles and the RX station vertical setup along with K3s, Yaesu Quadra Linear and the computers ready to go before the kick off, what we wasn’t expecting was the poor conditions. It was nearly impossible to get any sort of run on 20/15/10m and lots of the stations in the All Asian contest flatly refused to work us and sometimes in a pretty rude manor (Think they need to chill out a bit?).

Never the less we plodded on and worked what we could. After fish/sausages/chips for dinner, conditions seemed to start to pickup and I managed to get a few small runs to North America then about 11pm till 1am managed a big pile up to the States which was good fun and boosted callsigns in the logbook no end.

40m was also a pretty decent band through the night but we had problems on 80m due to lots of static crashes. This always seemed to happen around the time of the other station giving the serial number which got very frustrating.

Sun rise soon appeared Sunday morning and after working a bit of DX on 40m we shifted back to 20m to be greeted with a reasonable pile up for a while, then rest was spent calling CQ and working multipliers which the Spotting station was passing across. One problem I did find was due to vision being a bit poor sometimes missed the “spots” showing on the logbook!

Like normal soon as the contest was due to finish the heavens decided to open, but thankfully by the time it got to taking the tents down they’d nearly dried off which was lucky. We ended up at the end of the contest with about 1102 QSOs including dupes, and we’ve got plenty of ideas on how to improve the score next year.
