These amateur radio repeaters provide a very valuable service to many stations, and in particular those that do not have particularly good locations or those amateur radio stations that are using only low power.
VHF FM Broadcasting Tutorial Includes:VHF FM basicsPre-emphasis & de-emphasisStereoFrequencies, channels & bandsVHF broadcasting is established in most countries around the globe.VHF broadcast technology provides excellent fidelity in terms of audio frequency response and background noise of all forms.
Amateur Radio Digital Modes Tutorial Includes:Digimodes summaryAMTORRTTYPSK31Packet radioPACTORWSJTWSPROne area of amateur radio that has grown by a significant amount since the introduction of personal computers is the use of digital modes of transmission.These digital modes provide a very interesting way in which to communicate over ham radio, offering different challenges to those presented by the more traditional modes of transmission.
Digital Radio Mondiale (DRM) is set to revolutionise broadcasting on the long, medium and short wave bands. Since the very earliest days of broadcasting these wavebands have been filled with signals that are amplitude modulated. These transmissions are of low audio quality and particularly in recent years there has been a move away from these bands to find higher quality transmissions.

Nikola Tesla was one of the greatest scientists in history. He was well ahead of others of his day.Much of the importance of his work has not been realised until recent years and as a result he is not accorded the full credit he is due.In his life he was something of an eccentric and he was a loner, having very few friends.
Avalanche noise is a form of noise that does not occur in most circuit, but can be experienced with PN junctions that are operated at the point of avalanche breakdown or close to it.Diodes like Zener diodes exhibit this and the effects can be filtered at source to remove it and prevent it entering other circuits.
