Charlie, 2E0FMZ<\/strong><\/p>\n

I had a wonderful and very memorable time at this year\u2019s winter YOTA camp. We attended lectures on satellites including OSCAR-100, jet engines and QRM hunting.<\/p>\n

We learned a lot about specific methods for reducing QRM, and I discovered that a balanced feeder is better than a coaxial, which can act like a pseudo antenna. I also learnt that baluns are important as omitting them can lead to an electrical charge returning to the radio and creating a charge in Morse keys and sometimes microphones.<\/p>\n

We built a small QRM detector kit consisting of six resistors, three capacitors and transistors, two diodes, a switch and a headphone jack. I think this tool will be very useful in the future as it will help me solve issues of QRM within my home.<\/p>\n

We were shown around one of the QRM hunting vans the radio communications agency in the Netherlands (Agentshap telecom) use to detect interference\/EMC cases. It had a lot of very specialist and accurate equipment they use to track down various interference issues.<\/p>\n

It utilised specialist antennas as well as highly sensitive SDR systems to accurately track signals down to a couple degrees of rotations relative to the antenna. It taught me that tracking down illegal or problematic transmissions isn’t a difficult task, and I learnt about how many illegal and pirate stations are located and seized.<\/p>\n

I enjoyed hearing about the history behind the OSCAR programme. As a result of the YOTA camp, I feel much more confident with many of the technical aspects of amateur radio in these fields. I will definitely be looking into a taking a crack at OSCAR-100 once I get the parts which include a satellite dish, LNB, and appropriate antenna such as Patch of the Year.<\/p>\n
