WSPR是一款能让你加入到全球低功传播信标网络的软件。 有了它，你不但可以使用自己的电台发射信标信号，还能接收同业余频段下其他有相似设备站点发出的信标。 各个参与的站点在接收信标的同时又将其上传到网页服务器，信号发射完成后，你可以分分钟在地图上查到接收地点和接收强度，地图上甚至能够显示信号的传播路径。 如果你在忙其他事情，只要保持WSPR在运行状态。 随后可以随时搜索数据库查看你信号被接收情况。 还能通过分析过往的信号报告，了解季节 …

WSPR (pronounced "whisper") is an acronym for Weak Signal Propagation Reporter. It is a protocol, implemented in a computer program, used for weak- signal radio communication between amateur radio operators. The protocol was designed, and a program written initially, by Joe Taylor, K1JT.

WSPR is short for Weak Signal Propagation Reporter and is pronounced “Whisper”. It is important to note right away that WSPR is not a QSO mode. It is used to broadcast a position, call sign and power level and see who hears and decodes it. Reports of these decodes can be sent and tracked on a central website. http://www.wsprnet.org.

WSJT-X and MAP65 are open-source programs designed for weak-signal digital communication by amateur radio. Normal usage requires a standard SSB transceiver and a personal computer with soundcard, or the equivalent. SDR-style hardware including the SDR-IQ, Perseus, SoftRock, and FUNcube Dongle is supported by MAP65.

WSPR, which stands for Weak Signal Propagation Reporter, is a program used to test the propagation paths of RF signals between amateur radio operators using a narrowband digital transmission protocol called MEPT_JT on the HF and MF frequency bands.

WSPR (usually pronounced “whisper”) is a software application that uses the transmission mode MEPT-JT (Manned Experimental Propagation Transmitter – Joe Taylor). In MEPT transmissions, the radio becomes a beacon that transmits for just under 2 minutes, transmitting callsign, locator and power information. Modulation is by narrow-band FSK.

WSPR mode implements a protocol designed for probing potential propagation paths with low-power transmissions. WSPR is fully implemented within WSJT-X, including programmable "band-hopping".
