A short-wave radio station is a radio communication device that operates at a wavelength of 100 to 10 meters (frequency of 3 to 30 MHz). Mainly used for transmitting voice, equal amplitude and frequency shifting . Amplitude modulation and single sideband modulation are employed when transmitting telephone signals. It consists of a transmitter, a receiver, an antenna, a power supply, and a terminal device. Generally divided into portable, vehicle-mounted and fixed stations. It has the characteristics of small size, light weight, etc ., usually adopts a whip antenna, and uses ground waves for short-range communication, and the power is usually several watts to several tens of watts.
HF is a software radio (SDR) short-wave (HF) low-power (QRP) transceiver that has been popular all over the world since its introduction and has at least 30,000 users. Its advantages are: small and portable, cost-effective , full-featured, direct-production software radio line models. For electronic enthusiasts who love DIY and hardware, this is a very good training glove that can be used to familiarize with the working principle of amateur radio transceivers. It can also be used by software enthusiasts who write code programming and code farming. This hardware, modify the source code by itself, increase or decrease some functions, give full play to your own coden technology skills, and make software modifications and upgrades to this machine as you like. For college students who study electronic technology,they can be used to test their level of learning. QRP communication enthusiasts can use the installed kit to perform various outdoor QRP communication, especially digital communication using PSK31, RTTY and JT65. For emergency communications, mcHF is a compact and portable emergency communications equipment.
