The Australian Radio communications (Low Interference Potential Devices LIPD class license 2000) with all amendments came into effect on 1 July 2009.

This document (LIPD 2000) includes the amendments to 2009 to allow devises that meet certain power levels on certain frequencies to be used without the need to apply for a license.

LIPD, (section 3, Note) states that LIPD devises must not cause radio frequency interference to other Radio communication devises.

The responsibility is on LIPD owners to resolve interference for example by retuning or stopping their operation.

The planet Saturn photographed in Infrared wavelengths.



This is the planet Saturn as seen by the Hubble Space Telescope using a near Infrared frequency Camera and Multi-Object Spectrometer.

A wavelength of 1 µm is indicated by blue and is clear atmosphere down to a main cloud layer.
Shades of blue indicate variations in the clouds particle, size and chemistry.
A wavelength of (1.8 µm is indicated by Green) and yellow colors indicate a haze above the main cloud layer.
A wavelength of 2.1 µm is shown in Red.
Red and orange colors indicate clouds reaching up high into the atmosphere.

The two different colours of Saturn's moons Dione (yellow) on the lower left and Tethys (green) on the upper right indicate they have different surface conditions.

All these wavelengths are reflected sunlight since Saturn's own heat glows only at wavelengths above 4 micrometers.

Saturn has 61 moons.

Infrared astronomy and X-ray astronomy look near the centre of our Milky Way galaxy. 

 

The centre of our Milky Way Galaxy seen at infrared frequencies compared to what is seen on X-ray frequencies (in the circle).

Infrared astronomy in Brown, Yellow and White is near the centre of our Milky Way galaxy.

X-ray astronomy in the circle in Black, White and Blue is also near the centre of our Milky Way galaxy.

The large infrared photo shows the area of X-ray glow along the plane of our Milky Way Galaxy near the centre of our Galaxy as seen from a telescope in space called the Spitzer Space Telescope (formerly the Space Infrared Telescope Facility, SIRTF).

This diffuse haze of X-ray light is from gas that has been heated to millions of degrees by winds from massive young stars, explosions of dying stars, and outflows powered by a supermassive black hole (called Sagittarius A, Sgr A) at the centre of our Milky Way Galaxy

 

Another telescope in space known as the Chandra X-ray Observatory looked at the area shown by a  small white circle that is marked near the bottom centre in the large photo. It is an area located only 1.4 degrees away from the center of our Milky Way Galaxy.

It found a total of 473 sources of X-rays detected in an area on the sky only about 3% of the size of the full Moon, one of the highest densities of X-ray sources ever seen in our Galaxy.

More than 80% of the seemingly diffuse ridge of X-ray emission was resolved into individual sources.

These are believed to be mostly white dwarf stars pulling matter from companion stars and double stars with strong magnetic activity that are producing X-ray outbursts or flares that are similar to, but more powerful than the flares seen on the Sun. These stars are unrelated to the large-scale structures seen towards the centre of the Spitzer infrared image, which are probably caused by X-rays from young massive stars.

How to build a radio station in Somalia.

How to build a radio station antenna in Somalia.

The Somalia team mount the antenna horizontally in Galkayo, North East Somalia. 

 

Abdikarim Nur Mohamud 6O0W directed the lifting of the Radio Free Somalia antenna (“Free for all to use” known later as Radio Galkayo) at the Galkayo Police station, Galkayo, North East Somalia in August 1994.

North East Somalia became the Puntland State of Somalia on the 1st August 1998.
