    In continuation to my previous post, I will start discussing how I solved the wireless distribution at my church in an economical way with a DIY Wireless Microphone Antenna Distribution setup. One of my many hobbies include amateur radio, which is the personal & experimental use of specific radio frequencies established by the FCC. My callsign is KD7QCU. Basically, I am a big nerd of radio stuff. I get to talk to people all around the world with my radio and antennas outside of my house. It is quite a fun hobby and our technological age with regards to RF...

    Ham Radio DX Channel ^ | Aug 27, 2019 | Ham Radio DX Channel
    I received a log periodic antenna designed by ham radio operator WA5VJB from Kent Electronics. They are rated from 2 to 11 GHz, so this model will cover several of the ham bands. These antennas are made on PCB's and are ideal for use in the amateur microwave bands as compromise dish feeds. In this video I do a test of such a feed versus my patch antenna on the 3.4 GHz band. https://www.wa5vjb.com/products1.html I mounted one in place of the original dipole feed on a 2.4 GHz (13cm) gridpack at the same focal point. Whilst gain will be down...

    Scott Manley Youtube channel ^ | Mar 15, 2021 | Scott Manley
    Over the weekend amateur radio tinkerers in Europe managed to decode some portions of the telemetry data broadcast by the second stage of the Falcon 9 when it's in orbit. This data was in a somewhat standard format, but decoding still required some custom tools to extract the bitstream from the signal and then some guesswork to figure out the exact format. There's still lots of unknown data, but most interestingly this gave access to the engineering cameras including one showing the interior of the liquid oxygen tank.

    I wanted a bit more “oomph” from my 1W 1.2 GHz HT, so I purchased a PC board Yagi to get another 6 dB. I have a Yaesu FT-911 1.2 GHz HT. It is a 1990’s rig gifted me by the wife of a Silent Key at my work. It is a sweet handheld, but with limited power.

    Those of us who are either in-house or independent EMC consultants can benefit greatly by assembling our own EMI troubleshooting kit. I’ve depended on my own kit for several years and it has proven not only valuable, but depicts a sense of professionalism in dealing with your own product development engineers, their managers, or your clients, as the case may be. Mine is designed around a Pelican 1514 roller case (http://www.pelican.com) that includes a padded divider, so it is easy to transport to the area needed. You’ll also want to order the optional lid organizer, model 1519, for carrying extra...
