The Ionosphere Part 2
The ionosphere makes up less than 1% of the mass of Earth’s atmosphere above 100km. It’s the part of our atmosphere that affects the passage of radio waves. But how? Ionised Oxygen atoms are the key to radio propagation and good DX. EUV and activity from our sun affect the MUF and LUF.
The inspiration for this video came from "Ionospheric Radio" by Kenneth Davies, an up-to-date survey of the theory and practice of radio wave propagation involving transmission through and reflection from the ionosphere. Kenneth Davies is a senior research scientist at the Space Environment Laboratory in Colorado.

The Ionosphere
Просмотров 4,4 тыс.2 месяца назад
The ionosphere is the ionized part of Earth’s upper atmosphere that extends from about 80 to 600 km above sea level. It’s a region within the thermosphere filled with charged particles that play a crucial role in radio communication by reflecting radio waves back to Earth. It also contributes to auroras and is ionized by solar radiation. This video briefly overviews the 3 regions of the Ionosph...
MADs

Every so often here in Victoria (VK3) we have Microwave Activity Days otherwise known as MADs. These usually ad-hoc, but sometimes planned events, are where amateur radio operators passionate about microwave communications find themselves on hilltops working other like-minded amateurs. It’s an event where microwave enthusiasts can put their gear through its paces. This video will give you an in...
How to update the Icom IC 905 Firmware
Просмотров 3933 месяца назад
Updating the firmware of any radio keeps it running at its best and the IC-905 is no different. New features as well as engineering tweaks are added regularly, especially in radios that are new to the market. This video will show you how easy it is to update the firmware in your radio. You’ll need a micro SD card formatted in the 905 to copy the new firmware to. For context this video is part o...

On Sunday, February 4 2024, the Ballarat Amateur Radio Group hosted one of the best Hamfests I’ve been to in years. It was hot, but that didn’t deter hundreds of amateurs from far and wide making the pilgrimage to the central Victorian town of Ballarat. Here are some highlights of the day including a look at Icom's IC-905 24GHz concept model, Ian VK5ZD's 122GHz transceiver, and a host of local ...

10w power amp for 5.7 GHz 6cm amateur band
Просмотров 2,1 тыс.Год назад
Getting more than 250mW on the 6cm microwave band was an onerous task up until recently. SG Laboratory has produced a 5.7 GHz 10w PA. This amplifier has been developed and produced for industrial use but is matched well for the 6cm amateur band. It is based on the latest GaN power transistor from Cree/Wolfspeed. There is no switching around the amp, so it's something you'll have to do should yo...
Before you begin your adventure in microwave

And now for something different - Sporadic E propagation in 2 minutes (ish). If the comments are encouraging, there'll be more 2 minute-ish videos! Feel free to suggest topics. Sporadic E propagation is a type of radio wave propagation that occurs in the E layer of the ionosphere. The E layer extends from about 90-120km above the earth’s surface. Here's how it works More at bit.ly/3Ymaxao 00:00...
Getting on the 6cm microwave band
Просмотров 2,3 тыс.Год назад
Looking at getting onto the microwave bands? Here's one way. The 6cm or 5.7 GHz amateur radio band is accessible to standard and advanced licensees in Australia. It’s the higher of the two WiFi bands that doesn’t seem to suffer the noise problem like its poor 2.4 GHz or 13cm cousin. Antennas are cheap and readily available in the form of dishes and panels. So if you’re keen to dip your toe into...
12v shack backup - choose quality powergates over junk

Power backup comes at a price. Choosing quality over junk. Power gates, power paths, power plus, power mini, there are so many names for devices that switch to a battery for power when your mains supply fails. These devices are suited to both shack and portable use. Some have solar panel inputs without the need for solar regulators as it's all built-in. Choosing quality power switching over jun...
