Every legal amateur radio operator in the world has a unique callsign assigned to them by their government, and many of us are better known by our callsign than our given name. But what world event was it that caused these monikers to be? Why are they constructed the way they are? Watch this video I put together as presented at the QSO Today Expo in March 2021, and discover for yourself the storied history of the ham radio callsign!
73! Mike Ritz, W7VO

When I was a kid one of my mentors for ham radio was Gus, the original holder of call sign W0CC. My novice license, KN0ZBA was issued on February 29,1960 (leap day) and had a listed expiration date of February 29, 1961 - one year later. The bureaucracy had not taken the leap day into consideration as far as the one year term. Since that date never existed my novice license technically never expired. In any event I upgraded to a General license (K0ZBA) before the year was out. I still have that license at 75 years old.

In the late 1950's my uncle would pull up in his Cadillac with license plate W6PPO. We would talk to people in Europe sitting in our driveway. Great fun. Your video brought back some wonderful memories.

..going along with the group here, I had WV6KJK as a novice between 1961-1962. After high school, college, my first four years in the USAF, I got my second novice license and the call sign, WN6EPZ, from 1974-1976. Then, during a period of unemployment, I studied and went from "civilian" to the glorious advanced class license - one below amateur extra class, the top license. The call sign I received was KB6HK. The FCC changed the rules on "vanity calls" allowing techs up to advanced to apply for 1x3 format calls and I got K6WHP, the call I now hold. Finally, in 1996 I got my code speed up to 20 wpm and passed the extra class license but kept the K6WHP call sign. I became trustee for two clubs and got the calls, N6ABV, my late father's call, as well as KLR6LP, the call sign of the Lake Perris QRP Club. ..so that's about it. There's five minutes of your life you'll never get back.

I was WN4BOU in 1964 when I was 14 yrs old then WB4BOU which I lost while moving around and not renewing my license in time. So I took the General test again getting N4OHB to work CW which is all I have worked since my early years in the 60s. I then got my Advance and Extra class as N4OHB because it was a much shorter and easier to copy sign in cw. I did get into the 40-45 wpm CW group in the lower 25htz of the bands for a while but switched to QRP from 80s on. Have worked hams like Barry Goldwater, J Edgar Hoover's grandson, astronauts in airplanes , floating lighthouse op on an Alaskan coast . What I do miss is working the Navy CW ops from WW2 who always used "bugs" very well. I could always tell who they were when they were tuning up . Sadly they are all gone and so is CW from test requirements. And sadly a lot of kids no longer build CW transmitters as I did for a high school science fair project using tv parts and military surplus!

Sounds familiar. I got my novice in 1959 (WV6FAP) which I lost when I went into the Navy. I built my first CW transmitter from scratch like you in High School too for a science project. 6V6 oscillator and a 6L6 final with hand wound coils for 80 and 40, xtal controlled..(sound familiar??).. Got my current call in 1964..... 73's de WB6PVC

I am glad CW requirements are gone. I am getting back into the hobby mainly because of that. Times and technologies change. I think it was detrimental to the hobby for many to advance in the ratings. If some want to use it that's fine. But this isn't the 1940's any more.

Thanks, John. I had to cut what was originally about a 40 minute live club presentation into one that would fit into the 22-25 minute time limit for the QSO Today virtual hamfest. So, I left out anything related to current vanity calls that started in about 1996, and also the unique bi-centennial calls of 1976. Remember those? ;-)

Greetings from the UK, novice 2E1GPA graduated to M1DQE after the 'slow Morse' test. UK call signs are now permanently allocated at no cost, it seems the costs of administering the renewable license system exceeded the receipts! I only took the exams to support my daughter when she took them, and I never struggled with real RF equipment as e-mail and Skype were also around!

Another item regarding the W andK delineations was that the FCC had two main locations for their offices. TheW stands for Washington and the K stands for Kansas City. During WWII, those that were part of the Civil Defense, were still allowed to operate within a strictly confined area, on specific frequencies and at specific times, usually overnight. Thus extended through the 50’s And 60’s. As of 1960, one of the exercises for the CD was to assist in possible dirty bomb locating, One night my dad let me assist him in one if these drills. He had received an official ordinance map of NYC, so he taught me how to read this kind of map. As the night progressed, he was sent various coordinates which I then found on the map. The final coordinated I located indicated that this location was in the middle of Jamaica Bay. We were the inly station that got the location correct. Although the command had wanted it to be on the occupied island there so units could be dispatched to the location.. Command had made the mistake. By the way, the only antenna my dad used was an old Circle X TV antenna. I can only assume it worked as well as it did as satellite dishes use the same basic shape. He was even able to do moon bounce from it and was able receive signals from Florida. I know some of the other Hams were astounded when he told them what type of antennae he used.

In 1951, the novice class was added, that had either WN or KN prefix, it was a rite of passage when upgrading to remove the N. Its been three years but I finally got that joke why my elmers were hounding me about eventually getting a vanity when I went to General. Yes, its true that we don't own our station licenses, they are leased to us by the FCC on a contractual and conditional basis. But when you're issued a call that call is uniquely yours. 7,800,000,000 people in the world and that call letter combination is uniquely identifying you. Its something special, for me luckily its also easy to key. Great video, thanks for the breakdown in the lengthy ham history. 73 de KN4GEI

Hi Mike, I wish more of us within the ham community would stop calling our licensed communications skill set a hobby. In all reality, amateur radio should be considered more of an avocation than simply a hobby whereas, one can make a living at one's 'hobby' be it building models or collecting rocks or panning for gold but, we may not create income or "make money" by communicating over amateur radio. We both know this is strictly prohibited. One can have a hobby building transceivers and make money selling them but using said transceiver is not a hobby, it is a service conducted by someone that is considered less than a professional. Communication over amateur radio is a public service regardless if if the traffic is for pleasure, safety, or emergency. Now, collecting QSL cards, there's a hobby! Thanks for the extremely informative video. I enjoyed the history.

He enlisted as a radio operator and afterwards worked as an electrician.

But what puzzled me when I got my general in 1958 was the "9" in his call, as we both lived in Missouri. By 1958, Missouri was in the zero district.

My first becoming aware of Ham Radio was at a family friend (SZ-3DW), now long passed away, in about 1977. Uncle Don Wilson acted as relay station for motor rally races being run in a mountainous region of the country. He was in Oranjemund and the races were being held near Cape Town. In those days you were a "real ham" is you had built some of your own equipment, with Heathkit being the better known kits. Now I am retired and may just take up the hobby.
