The Ionosphere
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 Ionosphere, how they work and how they were discovered. Do you know how the E layer got its name? Do you know what the Appleton Layer is?

How to update the Icom IC 905 Firmware
Переглядів 3322 місяці тому
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...

10w power amp for 5.7 GHz 6cm amateur band
Переглядів 1,9 тис.10 місяців тому
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...

Getting on the 6cm microwave band
Переглядів 2,2 тис.Рік тому
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...

    Back in the 1980's I used to listen to NFL games on the U.S. Armed forces network with my radio in the U.K. I'd get the early game in, but at around 21:15 the signal would get weaker and weaker until all you could hear was static. I never knew why. . . Now I know! Thanks!!

    8:15 with regards to the meteorite debris clustering in the upper atmosphere, something like the aurora, our magnetic field concentrates Solar material in the exosphere, who not a similar phenomena with tiny fragments of iron caught up in the upper level winds and heat energy from the surface to act like a reflective cloud held up over a region? I have to imagine it was am exciting time to be a ham in the 50's and 60s when the military was releasing materials in the sky to see what the effects were.

    FYI Appleton knew the "E" layer as the Heaviside-Kennelly layer, predicted many years before. His experiments in radio wave reflection detected three layers, which he identified as D, E and F in order to allow for the possibility that there might one day be layers detected lower than the D layer. No such layers have been found.
