MacLoggerDX is a full-featured amateur radio contact logger for macOS with Transceiver control, Rotor control, Callbook lookup, QSL handling (Hardcopy / LoTW / eQSL / Club Log), DX Cluster and spotting, and basic contesting support.
An 802.15.4 radio module is a small device used to communicate wirelessly with other devices according to the IEEE 802.15.4 protocol. This table lists production ready-to-use certified modules only, not radio chips. A ready-to-use module is a complete system with a transceiver, and optionally an MCU and antenna on a printed circuit board.
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose ...
Satellite radio uses the 2.3 GHz S band in North America for nationwide digital radio broadcasting. [6] MobaHO! operated at 2.6 GHz. In other parts of the world, satellite radio uses part of the 1.4 GHz L band allocated for DAB. [7] Satellite radio subscribers purchase a receiver and pay a monthly subscription fee to listen to programming.
The Enhanced Position Location Reporting System (EPLRS) is a secure, jam-resistant, computer-controlled communications network that distributes near real-time tactical information, generally integrated into radio sets, and coordinated by a Network Control Station. [1] It is primarily used for data distribution, position location, and reporting.
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
Narrowband FM is used for voice communications in commercial and amateur radio settings. In two-way radio, narrowband FM (NBFM) is used to conserve bandwidth for land mobile, marine mobile and other radio services. A high-efficiency radio-frequency switching amplifier can be used to transmit FM signals (and other constant-amplitude signals).
Comparable to the American SCR-508 tank radio, which covered a similar frequency range (20-27.9 MHz) at 25 watts and the SCR-608 artillery variant (which operated in the 27-38.9 MHz frequency band) The major difference between German Army tank sets and US Army tank and artillery sets was the American use of FM for the high-HF/low-VHF bands.
