Using the WSPR Mode for Antenna Performance Evaluation and Propagation Assessment on the 160-m Band

In the last couple of years, use weak signal propagation reporter (WSPR) has grown significantly in radio amateur community and beyond. This protocol allows to probe potential paths between transceivers, operating at a low-power level. The decodes received signals translates them into appropriate signal-to-noise ratio levels, which reveal possible transmitter receiver using ionospheric reflections. this article, specifically 160-m band is addressed. used less intensity for WSPR communication, compared other bands (80 m 40 m). Additionally, specific features such as link performance Earth’s electron gyro-effect. aim article address these experimentally. First, two identical stations are conditioned compare different antennas. Each setup, separated by limited distance, generates almost SNR reports, allowing comparison Second, more extended experimental investigation path on reveals information wave behaviour receiver. first experiment allowed identification most optimal antenna, band. second shows that values can vary depending polarization shift signal. Possibly, be linked effect magnetic field Earth via gyro-frequency.
