WSJT-X implements communication protocols including FST4, FST4W, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, WSPR, and Echo. These modes facilitate reliable, confirmed QSOs under extreme weak-signal conditions. JT4, JT9, and JT65 utilize a nearly identical message structure and source encoding, employing timed **60-second** transmit/receive sequences synchronized with UTC. JT4 and JT65 are designed for EME on VHF/UHF/microwave bands, while JT9 is optimized for MF and HF, offering **2 dB** greater sensitivity than JT65 with less than 10% of its bandwidth. Q65 provides submodes with varying T/R sequence lengths and tone spacings, suitable for EME, ionospheric scatter, and weak signal operations on VHF, UHF, and microwave. FT4 and FT8 operate with T/R cycles of 7.5 and 15 seconds, respectively, supporting enhanced message formats for nonstandard callsigns and contest operations. MSK144 is engineered for Meteor Scatter on VHF bands. FST4 and FST4W target LF and MF bands, achieving fundamental sensitivities near theoretical limits for information throughput; FST4 is for two-way QSOs, and FST4W for quasi-beacon WSPR-style transmissions, without requiring the strict time synchronization of protocols like _EbNaut_. WSPR mode enables propagation path probing via low-power transmissions, incorporating programmable band-hopping. The **WSJT-X 2.7** General Availability release introduces the QMAP program, Q65 Pileup, SuperFox mode, a Hamlib update option, and a Message System. SuperFox mode transmits simultaneously to up to 9 Hounds with a constant envelope waveform, providing approximately +10 dB system gain compared to older Fox-and-Hound operations. _WSJT-X 2.7_ for _Windows_ platforms includes _MAP65 3.0_, a wideband polarization-matching tool for EME. The **WSJT-X 3.0.0-rc1** candidate release represents a major revision with new features, some ported from _WSJT-X Improved_. This software is available for _Windows 7_ and later (32-bit/64-bit), various Linux distributions (Debian, Ubuntu, Fedora, RedHat, Raspberry Pi OS), and macOS (10.13 through 15).

PropView is a free application that uses the included VOACAP, ICEPAC, and IONCAP engines to graphically display band openings between two locations over a specified 24 hour period. It can also build schedules for the IARU/HF beacon network and automatically QSY your transceiver to monitor each scheduled beacon.

Comprehensive listing of all known current HF beacons from IARU Region 1 HF beacon coordinator

This design represents the smallest practical antenna for Oscar-13 mode-S. Perfect beacon reception at all times is possible, and acceptable SSB even at 43,000 km range.

The NCDXF/IARU International Beacon Project schedule provides precise transmission start times for 18 beacons operating on 14.100 MHz, 18.110 MHz, 21.150 MHz, 24.930 MHz, and 28.200 MHz. Each beacon transmits every three minutes, cycling through its callsign at 22 WPM followed by four one-second dashes. The initial callsign and first dash are sent at 100 watts, with subsequent dashes at 10 watts, 1 watt, and 100 milliwatts, enabling **propagation analysis** across varying signal strengths. The schedule lists the minute and second within each hour for the first transmission of each beacon on its respective frequencies. This resource allows **DXers** and **contesters** to accurately predict beacon transmissions for real-time propagation assessment. For example, 4U1UN transmits first at 00:00 on 14.100 MHz, followed by VE8AT at 00:10, and W6WX at 00:20, continuing the sequence. The page also notes recent hardware upgrades, such as the installation of IBP 2.0 controllers with Icom 7200 radios at some sites, and provides status updates for beacons experiencing hardware failures or those not recently heard, aiding in troubleshooting and managing expectations for monitoring.

This resource provides a historical listing of **unlicensed amateur radio beacons** active in the United States as of December 1993, specifically detailing both **LOWFER** (Low Frequency Experimental Radio) and **MEDFER** (Medium Frequency Experimental Radio) operations. The data includes beacon frequencies in kilocycles (Kc), identification codes, state locations, and the callsigns or names of the beacon operators. Frequencies range from 166.667 Kc for LOWFER to 1706.0 Kc for MEDFER, illustrating the spectrum utilized by these experimental stations. The information was originally compiled by Mark Burkart and relayed to the rec.radio.shortwave newsgroup by Rick Robinson, KF4AR. The list serves as a snapshot of experimental beacon activity from the early 1990s, offering insight into the types of operations and the individuals involved in unlicensed, low-power transmissions. It highlights specific beacon IDs like "ABC SC" on 510.5 Kc and "GK HI" on 1620 Kc, alongside operator details such as Todd Roberts (WD4NGG) and Herb Vanderbeek (WY6G). While not a current operational guide, it is a valuable historical document for those interested in the evolution of LF/MF experimental radio and the early days of internet-based amateur radio information sharing.

The purpose of the APRS-Beacon is to provide simple APRS-compatible position beacons for up to three Objects. It is designed to 'stand alone' and does not monitor other traffic on the frequency. It can use a single-port TNC (in 'native' mode), a single- or dual-port TNC in Kiss mode or the AGW Packet Engine in order to transmit on up to four radio ports.(When running with AGWPE, APRS-Beacon will also work with Windows 2000)

For radio amateurs engaged in propagation studies and DXing on the 6-meter band, understanding the distribution of active beacons is crucial for assessing band openings and signal paths. This resource presents a static map compiled by _Carl-Axel Lindberg, SM6NZV_, illustrating the geographical placement of European beacons operating on the 50 MHz band, which is vital for monitoring sporadic-E, F2-layer, and other propagation modes. The map, last updated in April 2002, serves as a historical reference for beacon locations, allowing operators to correlate observed signal reports with known beacon positions. While not real-time, it provides foundational data for analyzing past propagation events and understanding typical beacon coverage areas across the European continent. Operators can use this information to identify potential receive stations or transmit points for future _DX contacts_ on the _Magic Band_.

A vertical antenna specifically designed to work with the 80 meter CW beacon keyer

This simple 30m QRSS beacon is built entirely out of junkbox parts, the only component purchased specifically for this project was the 10,140kHz crystal. Hans Summers' 30m QRSS beacon project emphasizes simplicity and low cost, built almost entirely from reused parts. Key components include a 10,140kHz crystal, a 2N3904 transistor from a broken DVD player, and an ordinary LED used for frequency shift. The oscillator is stabilized in a polystyrene box, with power amplification driven by recycled copper PCB. Output power peaks at 360mW, and a custom 50-ohm dummy load manages heat. Though aesthetically unconventional, the beacon works effectively, fulfilling the project's low cost aim.
