Add FST4W for Antonio (IK1HGI) and new library for OLED

Wiring

• Wire the schematics below

• Adjust output filter as filter design calculation

filter design

• Use mini tore calculator to find inductor turns

mini tore calculator

• Check filter with a VNA (optional)

Programming

• Copy libraries files into Arduino/library folder

• run wspr.bat put your callsign, locator and power and generate symbols.

• Paste symbols from symbols.txt into WsprSimple.ino with commas

	int wsprSymb[] = {3, 3, 0, 0, 0, 2, 0, 2, 1, 2, 0, 2, 3, 3, 1, 0, 2, 0, 3, 0, 0, 1, 2, 1, 1, 3, 1, 0, 2, 0, 0, 2, 0, 2, 3, 2, 0, 1, 2, 3, 0, 0, 0, 0,
	                  2, 2, 3, 0, 1, 3, 2, 0, 3, 3, 2, 3, 2, 2, 2, 1, 3, 0, 1, 0, 2, 0, 2, 1, 1, 2, 1, 0, 3, 2, 1, 2, 3, 0, 0, 1, 2, 0, 1, 0, 1, 3, 0, 0,
	                  0, 1, 3, 2, 1, 2, 1, 2, 2, 2, 3, 0, 0, 2, 2, 2, 3, 2, 0, 1, 2, 0, 3, 3, 1, 2, 3, 3, 0, 2, 1, 3, 0, 3, 2, 2, 0, 3, 3, 1, 2, 0, 0, 0,
	                  2, 1, 0, 1, 2, 0, 3, 3, 2, 2, 0, 2, 2, 2, 2, 1, 3, 2, 1, 0, 1, 1, 2, 0, 0, 3, 1, 2, 2, 2
	                 };

• Adjust frequency

#define frequence 7040100
long factor = -1500;

Usage notes

• Program Arduino Nano
• Adjust RTC clock by typing "h" key on serial monitor

• Connect any HF antenna

Beacon transmit every 2 min, monitor transmission with your receiver and adjust frequency "factor" offset if there is outside the WSPR band

• Enjoy WSPR beacon.

the src directory contains other programs like :

• Rtty, PSK, QPSK, Hellschreiber, JT65, JT9, WSPR and FT8 encoding exemples

• And FSQCall beacon test

• Telemetry is saved into FSQCALv042\Shared\data.tlm
• File can be changed into FSQEncode.ino
