Space weather looking good for space exploration

While NASA is delighted that the next solar cycle is predicted to be the weakest in 200 years, many others who rely on the ionosphere to produce high frequency propagation (HF) will be less enthusiastic, while satellite owners will also be delighted with a lower possible solar impact on their operations. The last astronauts of […]

RF noise is killing communication

What climate change is doing to cause erratic and unforeseen weather, so is uncontrolled increases in radio frequency (RF) noise affecting communications, eventually leading to disruption. Like climate change, there are many who doubt its existence and claim it is just a passing phase. The increasing level of the RF noise floor is created by […]

The millimetre bands are useless! Are they?

From the dawn of radio by Marconi and others, some segments of the radio spectrum were declared of no real value. The high frequency (HF) bands (shortwave) first earned this “useless position” because long and medium waves were considered the only frequencies of value. Then, radio amateurs pioneered international communications on shortwave and before long […]
