WORK IN PROGRESS
Weak signal beacon project
The project consists in the creation of a low power WSPR beacon. The goal is to study propagation, based on short and long term statistics.
WSPR implements a protocol designed for probing potential propagation paths with low-power transmissions. Normal transmissions carry a station's callsign, Maidenhead grid locator, and transmitter power in dBm. The program can decode signals with S / N as low as -28 dB in a 2500 Hz bandwidth. Stations with internet access can automatically upload their reception reports to a central database called WSPRnet, which includes a mapping facility.
Low power WSPR and FT8 beacon
For FT8 and WSPR propagation studies, a Flex 1500 transceiver with adjustable output power from 0.05 to 5 watts is used. Tests are primarily conducted at very low power.
