Supported modes:
- WSPR2
- WSPR15
- JT65
- JT9
- JT4
- ISCAT
Key features:
- Internal encoder for WSPR and ISCAT.
- Simple "in code configuration".
- Useful on-line mode configurator.
- TX start moment is controlled by extremely accurate I2C real-time clock Ds3231.
- Terminal-based command line interface.
- Support band-hopping with LPF auto selection.
- Pin-compliant with QRP-LABS Arduino shield and relay-switch board.
To configure base frequency, step of FSK manipulation, T/R interval, mode - please use javascript based configurator: http://ra9yer.blogspot.com/p/si5351-configurator.html or open local configurator : ./doc/band_configurator.html
The WSPR beacon message in defined directly in the code in text form. However, to generate symbold stream for other modes like js65,jt4,jt8 you will need command-line utilities jt65code, jt4code, jt9code.
Updated at Jenuary 2017. Experimental feature: GPS module instead of DS3231. Please see macros TIME_SLICE_GPS/TIME_SLICE_DS3231 in si5351-beacon.ino file.

Please configure terminal with newline termination.
Command setdate - in-chip datetime will be updated as soon as you hit enter.
If the folder you downloaded has name 'si5351-beacon-master' please rename it to 'si5351-beacon'. It is Arduino obligatory that the folder name should have the same name as name of *.ino file.
The project is self-contained. No need to download extra libraries or put any provided sources outside the directory.
Si5351 module, arduio-shield, LPF's, relay-switched board was purchased from http://www.qrp-labs.com
