M0EZP Amateur Radio Station - QSL Card

M0EZP is an Advanced Class amateur radio station on the air since June 2004 and previously under the callsign M3EZP from Oct 2003. It is operated by David who first sat the Amateur Radio exam almost thirty years earlier in December 1975. He failed the first section on operating practice and regulations but passed the second section on radio theory and design. It was a three hour  City & Guilds written paper in those days and at age 13 it scared me somewhat from trying again soon after. More on my radio story

Although commercial equipment is used, much of the station equipment, such as AM, CW and Side-band transmitters and receivers, antenna tuning units, frequency counters etc are homebrew.

My radio activity is quite limited at the moment as my current QTH is an apartment in Bailiff Bridge.

        75th Anniversary of D-Day

        Unfortunately my HF equipment is off the air still but the 75th Anniversary of D-Day reminded me of the excitement when I had my M3 license of working GB6OD, South Dorset Amateur Radio Society, who 15 years ago put up a Special Event Station for the 60th Anniversary of D-Day. I was limited to 10 watts of course but was able to work GB3OD on both 80 and 160m on 5th June 2004 using my then base-loaded inverted-L Read more →

        Flat Dweller – Magnetic Loop built by G4NTA

        My radio wings are unfortunately rather clipped in my current location of being in an apartment. A good friend of mine, retired electrical engineer Peter G4NTA, offered to lend me his magnetic loop to see if that would get me back on the air from home QTH. Peter built his loop from a design in Radcom in November 2010 by Tom Haylock M0ZSA. Tom’s design is based on an earlier one by John Hays G3BDQ published in November 2003’s Radcom. It’s best described as a slinky toy wrapped around a hula-hoop (approx 60cm / 2-feet diameter) with a 120pF variable Read more →

        GB3RS Operating from National Radio Centre

        GB3RS operating from National Radio Centre at Bletchley Park, near Milton Keynes, Buckinghamshire, MK3 6DS is an absolute must! The park was the centre of our WW2 code breaking activity where many ‘secret’ heros strived to decrypt enemy messages and it is estimated saved many millions of lives by shortening the war by two years. The non-military spin off from mathematician Alan Turing and his colleagues was of course the device you are using to read this – the computer! Radio was central to their operations being the medium by which most of the messages was being received. So Bletchley Read more →

      • FT-747GX arcing or relay chatter?
        FT-747GX arcing or relay chatter?

        Is my FT-747GX arcing or is it relay chatter?  Or…isn’t it embarrassing when you fail to spot the blinding obvious! Wanting to do more portable operations due to my current apartment QTH, my Yaesu FT-747GX was awoken from a few years of slumber. Of course it makes sense to test the rig first doesn’t it and so I did. I plugged in the DC, connected the coax to my SWR meter and then to a dummy load. I switched the rig into transmit with 10 watts and was very disappointed to hear what at first sounded like arcing between capacitor Read more →

      • Portable ops at Blackstone Edge
        Portable ops at Blackstone Edge

          Blackstone Edge is an escarpment in the Pennine hills forming a buttress to keep the Lancastrians out of the West Riding of Yorkshire! 🙂 It is an excellent location for portable ops, not least because of the proximity of the White House pub (meals and drinks)! Location: IO83XP (WAB: SD91) Postcode: OL15 5LG access via A58 Michael (M0APC) and I decided to have a /P day and although the perfect WX of recent days had passed leaving us with strong winds, rain, hail, snow but finally sun, it proved to be a fun day out with some interesting contacts.

      • New QTH
        New QTH

        As of 2015, my home QTH is the 3rd floor (top floor) of an apartment block in Bailiff Bridge. No opportunities for outdoor aerials exist here and so things are a bit restricted. I will have minimal access to my old QTH’s facilities for the next few months but essentially I’m limited to 2m at present. My 2m aerial is a 5/8 whip with a magnetic whiteboard underneath it situated on an ironing-board! Currently I’m running low power from my Kenwood TH-F7E into a Mirage Linear and getting about 25w output. Adding more foil around the ground plane seems to Read more →

      • One transister topband transmitter
        One transister topband transmitter

        Back in the 70s, I remember my friend Richard G4EIE building a one-transistor transmitter for 160m. It comprised a BFY51 transistor, crystal, L-C tuned circuit, a resistor, a couple more capacitors and a carbon microphone. It put out 250mW AM or 750mW CW (using a morse key in place of the mic). It was surprisingly effective! I’ve wanted to build this circuit ever since and surprisingly I waited 35 years!   The circuit was devised by Eric Elsey G3YUQ and was published in the Winter edition of Sprat in 1975. It has been republished in many other places since including Read more →

      • What is Amateur Radio

        Most Amateur Radio operators (Hams) are involved in Global communication; a great way to develops better understanding of geography, languages and cultures.

        Licences are granted after the operator has passed the appropriate examinations to ensure they have the skills to transmit relatively high power signals on frequency bands across the spectrum, with minimal risk of interference to others.

        Many Hams enjoy the achievement of using equipment they have designed or built themselves - aerials, transmitters, receivers and test equipment.

        Amateur Radio is often used to provide emergency communications, eg. Haiti, the Indian Ocean Tsunami etc. Click here for information from the Radio Society of Great Britain.

        In the UK, the Radio Amateur Emergency Network RAYNET provides communications to the emergency services in the event of emergency situations such as flooding after the loss of conventional telephone communications.
