Amateur Radios

While I patiently await hearing back about my CWNE application, I decided to pursue a goal I started back in high school. When I was a freshman, somehow I became interested in amateur radio, and wanted to become a licensed ham. I studied (with the online resources available way back then) and was prepared to take the exam at a local club. However, that weekend we had a snow storm and I was unable to take the exam and moved on to other interests. Little did I know that the fundamentals I learned back then would play a role in what I've made a career doing. I am proud to share, after recently studying for the technician exam, I successfully passed! I am now a licensed technician class amateur radio operator! While some may think it's an outdated form of communication, having been in the 802.11 world for 20 years, I'm fascinated by the phenomenon that is an RF wave. 73, KC1VUO

50 years ago today. Some amateur radio friends and I using the old CSIRO dish from the Dapto radio observatory for EME (Earth-Moon-Earth aka Moonbounce). @CSIRO gave the dish to the @University of Wollongong who let the local Illawarra Amateur Radio club (us) “play” with it. Transmitting in the 70cm amateur radio band, and cooking any low flying birds between us and the moon!

Ham radio repair side of D-lab electronics Yep, I have a pile of boat anchors (Ham radios) in the shop for repair. More have been coming in lately. Hams get busy when winter approaches. These old radios put out lots of heat to keep you cozy in the shack. They are heavy. Still operating after 60 years!

These kits were awesome. Great way to learn electronics.

The word ‘New’ when used to describe technology is usually a marketing slogan as most technologies we take for granted today are routed in old technologies which were merely expanded upon to become more advanced. A good example of this would be the telegraph key, the most popular due to its simplicity was the morse key. Its operation was simple, connect the device to a power source and a line which would be connected to a vast network of electrical cables and relayed by other telegraph stations. When the key was pressed the needle point would connect with a contact and complete an electrical circuit, sending an electrical impulse down the the line. The longer the key was held down the larger the impulse. This was the birth or modern telecommunication as after the development of the telegraph, Alfred Vail who was a friend of Samuel Morse who developed morse code together in 1838, which was a varied assortment of dots and dashes creating a binary language which would have a letter assigned to them. It was from this a text based messaging system was created. In 1855 David Edward Hughes invented the printing telegraph which used a keyboard (similar to piano keys) and a spinning type wheel to transmit letters. It was this device which gave rise to the teleprinter which was invented by Edward Kleinschmidt and replaced the telegraph completely by the 1920’s. The teleprinter also used a keyboard with letters and numbers ( similar to what we use today) which when used a series of electrical impulses were transmitted and then printed at the receiving end. This system also used a form of binary code in 5-bit consisting of X and •, this was known as the Badout-Murray code. It was by the mid to late 1970s however the teleprinter was replaced altogether by CRT-Terminals and dot matrix printers which in turn were quickly replaced by PC’s in the 1980’s. Both of these systems used an electronic keyboard with letters and numbers which when pressed and released would send a scan code consisting of 0’s and 1’s to the operating system which will register the column and row that in turn would display the assigned character on the screen. So remember, all the technologies and tools you use today which have been advanced upon to help facilitate faster productivity and output for your employer were once only used by experts in specific fields. If that doesn’t motivate you to ask your employer for a pay rise then nothing will. Good Luck!

One of my lab assistants, Jesus Hernandez Lopez, is an Electrical Engineering student here at Cal State San Marcos. He is a first in his family to go to college. Jesus is in his senior year at CSUSM. He aspires to be an RF Engineer; he is the Vice-President of the Amateur Radio Club, and arranged the Fox Hunt last week. Some pictures below show him field testing with his RF equipment on a cart - that's what we called Man-O-Van testing at Qualcomm. Another picture shows him testing antenna radiation patterns with equipment from Diamond Engineering. Happy Thanksgiving!!!

Dear Connections, I would like to share my Amateur Radio Certificate with you. Ready to explore new horizons in this world. Thank you to all trainees Mars on Earth Project (MoEP)

I just got my ham radio license in technician class - KJ5IYY. Aced the test. I missed the general class by one question, mostly because I wasn't studying for that. The general class test was a free add on so I guessed my way through it. I'm thinking about making it a life goal to see how many licenses and government permission slips I can collect. lol CDL B, Private Pilot Glider, TX CHL, FCC Technician, FCC GMRS, fishing, hunting. And then there's the organizations - CMRA, SCCA, IDPA, TSCEC, ARRL, etc. Any other suggestions for me to add to my checklist?

確か1977年頃にハムジャーナルに載ったFT-901のWIDTHの記事を読んだ記憶があり、それがQEX最新号に再掲されると聞いて買ってみました😌米軍がSDRを開発する20年前の技術です。 こんなの読んでた凄いな中2のオレ😎

📡TA2MFH. A New Step in My Amateur Radio Journey! 📡 In the past, I passed the amateur radio exam and earned a B category license. However, in order to improve myself further and obtain an internationally recognized certification, I took another step. In this process, I reappeared for the exam and earned the A category license, and now I am the proud holder of the internationally recognized HAREC (Harmonized Amateur Radio Examination Certificate). My call sign: TA2MFH 📞 This journey has not only expanded my technical knowledge but also helped me develop skills in communication, problem-solving, and continuous learning. Amateur radio is a great way to build connections across borders! I highly recommend this experience to anyone interested in the world of amateur radio. 73.🌍📡 ------------------------------------------------------------------------------------- 📡TA2MFH. Amatör Telsizcilik Yolculuğumda Yeni Bir Adım! 📡 Geçtiğimiz dönemde amatör telsizcilik sınavına girerek B kategorisinde belge almaya hak kazanmıştım. Ancak kendimi daha da geliştirmek ve uluslararası alanda geçerli bir belgeye sahip olmak amacıyla bir adım daha attım. Bu süreçte tekrar sınava girerek A kategorisi belge almaya hak kazandım ve artık uluslararası geçerliliğe sahip olan HAREC (Harmonized Amateur Radio Examination Certificate) belgesi sahibiyim. Çağrı kodum: TA2MFH 📞 Bu yolculuk, yalnızca teknik bilgi kazanmakla kalmayıp aynı zamanda iletişim, problem çözme ve sürekli öğrenme gibi birçok beceriyi geliştirmemi sağladı. Telsizcilik, sınırların ötesinde bağlar kurmanın harika bir yolu! Amatör telsizcilik dünyasına ilgi duyan herkese bu süreci deneyimlemesini tavsiye ederim. 73.🌍📡
