The next meeting of the LRS will be held on Wednesday 23rd March at 7:30 for 8:00pm at the Braid Hills Hotel. There will be not one but two talks, from two different Brians:

1.  "Low Cost Microwaves" by Brian Flynn GM8BJF 

Brian says: I will describe how to get up and running receiving 10GHz signals at low cost ~£20 and without any metalwork or soldering!

2.  "WSPR" by Brian Howie GM4DIJ

WSPR stands for Weak Signal  Propagation Reporting. It's a low-power beacon-like mode used to probe radio propagation paths and report the findings to an Internet database. The short talk will describe how it works and will include a live demonstration, subject to the usual gremlins.

At the meeting of the LRS on 12th March 2014 LRS Past-President John Cooke GM8OTI gave a very comprehensive talk about Astronomical Radio Sources. John was an astronomer in his working life (though not a radio astronomer!) and described how the Universe is seen using radio waves. This included an outline of the techniques used, before going on to describe the different radio sources observed, from those inside the Solar System, those in our galaxy and beyond, and out to the furthest detectable sources.

In light of the imminent loss of support by Microsoft for the Windows XP operating system from May of this year, LRS President Andy Sinclair MM0FMF (who knows a thing or two about computers) gave a timely talk "Whither Windows XP" at the LRS meeting on 12th February. 

Andy wrote: "I will give a talk about what people should be doing when WinXP stops being supported in May. A lot of people will have a lot of investment in XP software that is rapidly going to become obsolete. So suggesting how they can maintain that value whilst moving on may be well-received".  Full report.
