Ham Radio-By John G4YDM,  how I started in the fascinating World of Ham radio and how it leads me into the Telecommunications Industry, where I worked as an Engineer.

Ham Radio - How Did I Start in This Fascinating Hobby?

MY QSL CARD


It all started when I received a book called "wires bulbs and batteries." It was Christmas following my sixth birthday. I believe it was due to the fact that my parents had noticed their torch had been taken apart, and the components rewired together.

Ham Radio - How Did I Start in This Fascinating Hobby?

MY HAM RADIO SHACK
After studying the circuit diagram in the book on batteries and bulbs it seemed obvious that I was keen to explore electricity and how circuits worked together when a switch was activated and the bulb lit. I soon explored the school library and found a book called how to build a crystal set. These books are still available on auction websites at reasonable prices; I would buy one they still hold great information even today, fifty years on.

ONE OF MY TRANSCEIVERS FT-1000D 


May I suggest that you explore the secondhand market for a general coverage receiver? Listening to the Short Wave spectrum will give you a good grounding in what Ham Radio has to offer. It is better to buy a secondhand receiver from a reputable dealer, secondhand radios keep their value if you decide to sell it on if the radio is not for you.

Ham Radio - How Did I Start in This Fascinating Hobby?

MY HOMEBREW  AERIAL BALANCED MATCHING UNIT


For the more adventurous explorer, a radio kit is a good introduction to Ham Radio. A kit comes with all the components and a drilled circuit board which removes the time from having to source components separately from radio suppliers.

Ham Radio - How Did I Start in This Fascinating Hobby?

AN ICOM IC-7100 RECEIVER


If you decide to buy a Short Wave receiver, make sure it has the capability of receiving Frequency Modulation or F.M. My first commercial the receiver was used as a driver for a frequency converter. Using the ten-meter band as an Intermediate Frequency and the converter I could tune into transmissions on the V.H.F. Ham Radio allocation on 144 Megahertz.

Ham Radio - How Did I Start in This Fascinating Hobby?

A PYE WESTMINSTER I USED ON TWO METERS


Another excellent way to develop your interest in Ham Radio is to buy an ex Private Mobile Radio Transceiver, the type used by taxi companies and Utility services. Some of these transceivers can be easily converted to Ham Radio bands at a fraction of the cost of commercially designed equipment. There are many websites showing you how to do this.

Ham Radio - How Did I Start in This Fascinating Hobby?

A GRID DIP OSCILLATOR


In my opinion, building either a receiver or modifying a piece of commercial equipment, have many advantages for the newcomer to Ham Radio. 

The education is worth its weight in gold and you can go on to other modifications, including making fixed crystal-controlled receivers and transceivers into variable frequency rigs by building a variable frequency oscillator. 

There are plenty of instructions on the internet for the keen and practical Radio Ham.

Apart from building transceivers, mainly QRP for use on CW within the HF spectrum, I also enjoy the challenge of painting in a realistic form, I am sure you will agree that these portraits are photo-like, that, of course, is the aim of any realistic artist.

Ham Radio and its technical challenges go hand in hand with producing art like many of us who are interested in Ham radio-we have other passions-mine is art and photography, and CW I,m always trying to improve that particular skill associated with my Ham radio interest.

I only work in oil on canvas-nothing, in my opinion, comes near to vivid tonal color which an artist can achieve using oil paint. All these paintings are between 20x24 inches and 24x36 inches, sizes make a difference in perspective when creating artwork.

Oil portraits are created using linen canvas which has been coated in gesso before the subject is drawn and then colored. I have placed links to the Stadium of Light Sunderland and St James Park Newcastle below.

  Thank you for your comments about my oil portraits featuring Alan Shearer and Kevin Keegan, these paintings which I created a number of years ago still bring in emails from as far away as Australia and New Zealand, however a lot of people who write following my website uploads are from the North East originally and can appreciate many of my portraits and their connections.

Essentially I,m a portrait painter but photography has played its role in not only as a form of reference for paintings and portraits-it also acts as a memory jogger for people especially if they were born and lived in the Northeast for some time.

These pictures which were requested by many ex-miners who lived in Washington and have now emigrated to far distant lands including Spain and France, however, they all have fond memories of the F pit in Washington a sight that I saw every morning-I was born on Shafto Terrace which overlooked the F Pit Colliery.

These pictures show the colliery band marching down the front street in Washington and people walking behind the band along Richardson terrace to meet up with the coach to take them to Durham-the bus, as usual, is parked behind where Woolworth store used to be.

Thank you again for your comments about this website!

I tilted the Queen Mothers' head slightly to add movement to my work of art, tweaks to the composition make big differences to a portrait. Many enquirers have asked about why I painted a necklace and earrings these additions frame the painting before they were added the work looked a little flat, I think these additions also draw your eye more to the subject.

Ham Radio-the QSL card

Ham Radio-the QSL card


Ham Radio-the QSL card for John G4YDM

Ham Radio-the QSL card for John G4YDM


Ham Radio-the QSL card.  Starting out as a short wave listener many years ago using a home built HAC valve receiver, it was always a great achievement to pick up a rare radio station, although in those days my ham-radio activity was centered on listening to not only broadcast stations throughout the world I also had a keen interest in listening to the Brtish Telecom coastal radio stations who still broadcast the weather forecast and marine warnings including general hazards for shipping.


If you click the link above it will take you to HAC receiver kits, the website has the schematic diagram, one of the models I built was the K, and it still can be made today.

In those days being new and interested in picking up radio broadcasts from distant stations I was very keen to send the station a qsl card, my design was homemade, I would save pocket money to buy the stamps to send my reception reports around the world using the SINPO reporting system.


My efforts were rewarded and I received 100's of replies from broadcast stations throughout the world, sadly many are no longer transmitting on short-wave but still can be found on the internet and via satellite transmissions.

Utility listening was an area I became interested in during my SWL, Short-Wave-Listener days, marine and aircraft stations were a favorite, I remember being a member of the International short wave league a monthly magazine which was delivered by the postman, as you can imagine it was always very welcome and I would read the booklet from cover to cover.

When I obtained my first license, G6CHB, I was mainly involved with building transceivers for use within the VHF and UHF amateur bands, QSL-ing every station I worked during sporadic E lifts across the North sea, or throughout the British Isles, some of my most interesting QSO's involved working stations in the Orkney Islands and down into Jersey and Guernsey with trans-verters using an HF transceiver and its 28 Mhz output as an Intermediate Frequency.

Sending a QSL card nowadays using the direct method can be expensive but many of the national radio ham societies run QSL bureaus, where members send in their QSL verification cards, they are distributed around the world saving the participant money in postage costs.

A new technology also exists, its called EQSL, this is a web-based verification system, when used with Ham Radio Deluxe an electronic logging program, your contacts are automatically logged into HRD,  which records QSO's, including the date-time power and whether a QSL card has been sent or received, all at the click of a button.

There are many designs of QSL card to choose from or you can design your own and have it printed, my QSL card which you see at the top of this page consists of my call-sign G4YDM incorporated into the Angel of the North public artwork, pictures of other places throughout the Northeast are also included.

Thank you for your comments are suggestions and for reading my blog posts. vy 73 de John G4YDM
