    "GB100MZX Special Event"
    CARS Members

    In June 1920 with sponsorship from the Daily Mail newspaper, the Marconi Company broadcast the world's first live recital by a professional musician - the legendary Australian diva, Dame Nellie Melba.

    In a makeshift studio at the New Street Chelmsford factory, she opened her recital at 19:10 on 15 June 1920 by singing 'Home Sweet Home' and other popular favourites - the first offical UK Broadcast.

    The powerful Marconi company transmitter used in 1920 had been allocated the callsign MZX (Marconi Zulu X-ray). This event subsequently led to 2MT Writtle and later 2LO in 1922 Ė the birth of the BBC.

    Marking the centenary of this landmark event CARS Members will be operating GB100MZX in June 2020.

    CARS Members who wish to be operate should contact Colin G0TRM indicating timeslots and bands/modes they are able to commit to (HF/VHF, SSB/CW/Data or AM/FM), so they can be 'authorised'.

    March Meeting
    Tuesday 3rd Mar 2020, 7:30-10pm
    Oaklands Museum, Moulsham Street
    "Measure It!"
    Dave Ellis G4AJY & Bob G4MDB

    Click for Meeting Report

    The March meeting has a double installment on measurements - classical and modern.

    Meters: Firstly Dave Ellis G4AJY will kick off with the moving coil meter. These may seem to be out of date in the modern ham radio scene, but it can still do things that a digital multimeter can't - and you can pick them up for as little as a pound at a rally.

    This talk will explain how the meter is made, how it works, what you can do with it, and some special projects for your meter.

    Every ham shack should have one!

    VNAs: After the break Bob Tokley G4MDB will then give an insight into another measurement tool - really useful for Antenna Design & Measurements.

    He will describe the operation and functions of his two miniature Network Analysers as Bob owns both a miniVNA and a nanoVNA,

    So do pop along for another set of entertaining and insightful presentations.

    - all welcome

    The famous CARS Raffle also features.

    Directions / Parking

    You can drive all the way up Moulsham Street from Parkway but NOT the other way.

    Another way is to enter Moulsham Street after going round the Miami Roundabout (by Tesco), then along New London Road 200 yards, turn right into Moulsham Street and after 100 yards turn right again into the Museum.

    NOTE: There is plenty of car parking space but do not park directly in front of the Museum - that is reserved for people unloading kit and Disabled car drivers. Also - take care as there are three severe Sleeping Policeman as well.
