  2. Amateur Radio • Nature Amateur Radio is for self-training and experimentation, and is non-commercial in nature • Benefits Amateur Radio is of value in areas of • Technical Innovation • Emergency Communications • Development of Skills • International Friendship • Recreational Activity • The Foundation Licence is the entry level to Amateur Radio in the UK

  3. Amateur Radio Aspects • BANDS HF, VHF, UHF (and Microwave) • SPECIAL Repeaters, Internet Links, Packet/UIView, DX Cluster, RAYNET and Satellites/ISS • MODES Voice, Morse, Data/Packet, SlowScan TV, DSTAR • Voip- CQ100, EchoLink, EQSO • MODULATION CW, AM, SSB, FM, FSK, PSK31, RTTY etc • OTHER RSGB/Radcom, Clubs/Events, QSL Cards, Rallies, Contests, Awards

  4. Radio Microwaves THz IR UV X-rays Gamma rays The Electro-magnetic Spectrum Understand the Terminology for the Radio Spectrum

  5. Frequency Ranges • Remember ranges for Radio Frequencies (RF):- • HF: 3-30MHz • VHF: 30-300MHz • UHF: >300MHz • Compare with UK AC Mains = 50Hz • General Audio (AF) for Normal Hearing: 100Hz-15kHz • Frequencies for Audio Communications: 300Hz-3kHz

  6. Frequency Bands • Amateurs often refer to their bands in terms of either wavelength or frequency • Try to familiarise how bands may be described • HF: 7MHz = 40m 10MHz = 30m 29MHz = 10m • VHF: 50MHz = 6m 145MHz = 2m • UHF: 430MHz = 70cms • Note how the wavelengths decrease as frequencies rise - as per the earlier slide and the conversion chart

  7. Other Radio Users The radio spectrum is divided into agreed allocations to coordinate various uses The table opposite is a VHF example and may be used in the exam Amateurs have to share radio spectrum with many other services Other services may be in adjacent bands, but sometimes may be within an Amateur band

  8. Handheld Packet Data Satellites & ISS Contests TV Mobile Repeaters Microwave Amateur Radio at Large
