Meeting reports for 2019-2020

Geoff Crowley MM5AHO

                           Qualifications: B.Eng metallurgy, MBA, Yachtmaster Ocean Qualified skipper.                            Originally from New Zealand, Geoff moved to Scotland in 1993 from Iceland.

At the meeting on March 11th our good friend Geoff Crowley MM5AHO returned to talk about "How Not to Sail to the Faeroe Islands". There was a good turnout including two visitors from the Cockenzie club, in spite of the current coronavirus concern. 

Synopsis: Sleep deprivation is a problem in radio contesting and also in sailing single-handed. Geoff Crowley does both, and he recounted a few experiences during 2019 when lack of sleep caused problems in both sailing in his yacht Contender and in contesting. Some further examples from 2018, including a 1000 mile round trip to Rockall added interest about managing 24 hour activity.

This lecture was presented at the RSGB 2019 Convention by well-known RadCom author Mike Richards G4WNC, who also happens to be the OM of RadCom Managing Editor, Elaine Richards G4LFM. 

Mike gave the background to the Raspberry Pi series of low-cost single-board computers. These were developed starting in 2012 by Cambridge University to encourage more students to study computer science, whose numbers had been dropping. Manufactured at the Sony factory in Wales, the initial estimate was a need for about 1000 units.  As of mid-2019, more than 25 million had been produced, currently at a rate of 10,000 per week!

Mike described the various versions of the Raspberry Pi and their many applications.

Pete Bates GM4BYF gave a very interesting talk, with audio examples, of the technique of communication by signal scatter from the underside of an aircraft flying between the two stations. He also showed a number of items of test equipment to enable this technique - frequency standard, frequency meter and spectrum analyser, which are now available at remarkably affordable prices.

 

There was a turn-out of 15 for the LRS 2020 Video Night, presented by Peter Dick GM4DTH on 8th January 2020 at the Edinburgh Cine & Video Society in Fettes Row. Peter chose two films about the Cold War. 

At the meeting on 27th Nov, John Innes MM0JXI talked about the μBITX Radio - a low-cost HF transceiver kit.
