 ## TL;DR
 
 This project aim at decoding FT8 signals using an RTL device, usually connected to a Raspeberry Pi.

 ## Overview
 
-This non-interactive application allows automatic reporting of WSPR spots on WSPRnet. The inital idea was to allow a small computer like a Raspberry Pi and a RTL-SDR device to sent WSPR reports for VHF/UHF bands. This kind of lightweight setup could run continuously without maintenance and help to get additionnal propagation reports. The code is massively based on Steven Franke (K9AN) implementation of Joe Taylor (K1JT) publication and work.

 Most of RTL dongles use a cheap crystal, and frequency drift can effect the decoding & performance. The use of no-name RTL dongle for VHF/UHF bands usually require crystal modification, for a better one. External clock could be also used, like GPSDO or rubidium reference clock, aligned on 28.8MHz.
