Description of a PCB, also called "shield" allowing to build a universal rotator interface based on the K3NG software. Only the AZIMUT function is supported.
This PCB has been thinked to be used either with a LCD display or an Ethernet shield to allow a remote usage via IP, and for a rotator using a variable resistor for the azimut value .  (HAM IV or CD44 in my case)

The board includes :
- a 5V/1A regulator
- a header to plug an Arduino UNO and an Ethernet shield
- a HE10 male connector for to LCD display with a ribbon cable 
- a 5 pin DIN connector (+ ground shell) to connect the rotator control box
- 2 connectors for the "Clockwise" and "Counterclockwise" pushbuttons
- a multi-turn ajustable resistor VR2 for the azimut calibration
- an ajustable resistor VR1  for the LCD contrast
- 3 transistors for the CW, CCW, and BRAKE commands (open collector outputs)

I still have some naked pcb boards left. If interested, please feel to contact me.

The GR20 is a mythical long distance hiking trail that crosses the island of Corsica diagonally, from Calenzana in the North, to Conca in the South. 

The 200km trail follows the granite backbone of mountains that divides the island in two, many of which soar above 2000m altitude.  The GR20 is the best and toughest long distance hike in Europe ! 

I made my first GR20 in 2011 and promised myself to make it again with my son for my 60th birthday. So in 2017, i planned it and here are few advices. We made it in 10 days.
If you find this anything of helpful, please leave a post..

Remote solution for TS590s

While setting up my remote station, I quickly have been confronted to the problem of the limitations of the remote ease of use. The first one is the ability to change the VFO frequencies. My logging software LOGGER32 offers a lot of macros and an option to use the mouse wheel to change the frequencies. But during daily traffic or contesting they quickly have shown their limitations.

 On Twitter, I have seen that several hams have been using a small DJ controller for driving SDR receivers and transceivers. So I started thinking to do the same for the TS590s.
