    Wed 28 Oct 2026 – LRS at BHH – Blood Bikes Scotland – Phil Dodsworth & John Taylor Wed 11 Nov 2026 – 7:30PM – Open Meeting – Need to book your place – The end of the 198kHz Radio 4 long wave service – Mark Hughes GM4ISM

LRS MEETINGS

  • Wed 11 Nov 2026 – 7:30pm – Open Meeting – The End of the 198kHz Radio-4 Long Wave Service by Mark Hughes GM4ISM.

    There is an intention that every year we have an open evening with a keynote speaker, to which guests of the society are very welcome to attend. Because these are likely to be attended by more people than usual, they will be held in a larger room, and at an earlier time. Members and guests will need to register their interest in attending so that all attendees can be accommodated.

    This year the event is: The story of the Radio 4 Long Wave service on 200 and 198kHz by Mark Hughes GM4ISM

    Mark Hughes GM4ISM will tell the story of the last 35 years of evolution of the BBC Long Wave service and a glimpse at the engineering challenges that kept him (in the technical specialist team) busy as they pushed elderly transmitters way beyond their design life. The inevitable was warded off for a long time to a point that with changes in technology and the ‘political’ and contractual environment, we ended up with the services ceasing this year.

    Mark Hughes GM4ISM was a keen young radio ham (licensed at 14), and a career in Electrical Engineering seemed to fit. After graduating in Electrical Engineering at Warwick University he was recruited by BBC transmission. He worked extensively with antennas and transmitters, ending as team manager of the Forfar and Shetland teams before moving to a technical specialist team which started with four members and ended up with over thirty by the time he retired.

    11 November 2026 in the Gathering Bar at the Braid Hills Hotel.

    Note that the open event starts 30 minutes earlier than our usual talks: 19:00 for 19:30 start.

    Please reserve your place through this link:

    Please remember to add your email address on the form so that you receive an acknowledgment which is effectively your ticket for the event.


  • 28 Oct 2026 – Blood Bikes Scotland by Phil Dodsworth & John Taylor GM3JRT

    Blood Bikes Scotland (BBS) is a fully volunteer-run and donation-funded charity that provides a completely no cost courier service to 5 NHS Scotland Health Boards in Lothians, Borders, Fife, Central, and Tayside. BBS use both motorcycles and cars to move a variety of essential items 7 days a week, including: medicines and controlled drugs, tissue and blood samples, prescriptions, clerical and medical documents, medical equipments, and, occasionally, blood.

    The alternative courier services cost the NHS precious funds and BBS has saved NHS Scotland over £450,000 in courier costs in the last 12 months.

    Phil Dodsworth, a Trustee with BBS, will be giving a presentation all about BBS and how it functions. Our own Treasurer John GM4JRT also volunteers with BBS and will be on hand to answer any specific questions LRS members might have.

    9th March 2012 Aurora Summary by GM4BYF

    The double CME eruption of March 7th produced a complicated magnetic situation. Most likely both CMEs “ate” each other (hence weakening the strength of the magnetic field BZ). Only the latter part finally produced some aurora, but not as strong as it might have been. Finally the BZ turned south and around 12:00 UTC the…
