The Technical Handbook for Radio Monitoring HF is aimed to shortwave listeners, who are interested in digital signals. On over 350 pages with many figures and tables most digital waveforms are described. The book shall help shortwave listener to identify these digital signals which can be heard today. Digital waveforms like FSK, PSK, DSSS aso. with the used protocols and alphabets are described…
This book shall help shortwave listener to identify stations on shortwave. It contains more than 18000 frequencies from 82 Hz to 30000 kHz.
This book is describing common waveforms used on VHF- and UHF. It shall help the interested reader to identify these waveforms. The book is describing digital modulations like FSK, PSK, FH, DSSS aso. and used protocols. Systems like AIS, ACARS, GMS, THURAYA and others are described with spectrum pictures and detailed technical parameter.
