Wed 10th November 2021 :  Near Real-Time Propagation Measurement : Getting Started with WSPR - Colin Murray GM4EAU.



Precis: An explanation of WSPR, the Weak Signal Propagation Reporter protocol (pronounced Whisper) used to measure antenna performance and investigate radio propagation in near-real-time. The theory and practicalities were explained, followed by the steps required to observe WSPR traffic and to build and operate a WSPR station. The construction of a practical and simple standalone WSPR station was demonstrated using low-cost DIY modules. The author’s station was shown. Finally, two amateur-led applications for WSPR were outlined: tracking high-altitude balloons around the planet in real-time, and investigating aircraft flight paths with an update on recent research into the missing HM370 flight over the Indian Ocean. This talk was also received by 6 members via ZOOM. Full report - click.



The LRS autumn Surplus Equipment Sale was held on 20th October 2021 at St Fillan's Church, as usual. This year the participants were suitably masked and socially distanced. As this was the first sale in two years there was a lot of "stuff" including GM8GEC & GM3VLB SK items. Click for report.  

Pete GM4BYF sold many items from GM8GEC-SK. 


Treasurer Peter GM4DTH also ran the raffle.




The next LRS meeting on 26th January 2022 at 20:00h will be a Zoom-only presentation by Malcolm Hamilton GM3TAL -  "Using a Vertical Dipole Antenna (VDA) on a Scottish beach, Part 2".

Malcolm will talk about using vertical dipole arrays from the shores of Loch Fyne. He operated in the CQWW CW contest in November 2014 (LRS talk 11 Feb 2015) and again in 2021 along with Nick Henwood G3RWF, with a different set of antennas. He will share his 2021 experiences and attempt to draw some conclusions about the best aerials to use in practice."

Zoom log-in info soon.


On 12 Jan 2022 James Gentles GM4WZG gave a repeat on Zoom of his presentation from 8 Nov 2017 on the history of pirate radio in the UK in the 1960s and 70s. There was an excellent participation of 19 people.

This presentation was Video-recorded and it is hoped to provide access to the recording shortly.
