hamradio solutions vband interface

Here you can find a arduino sketch and building instructions for an simpel but good interface for https://hamradio.solutions/vband/

You need a ATMEGA32U4 and you can buy it here https://www.ebay.com/itm/255283295146

you also need a littel jack ..Thats all and it means that the price is only 5 US$

Basic setup if you want to use the keyer on https://hamradio.solutions/vband/

on the jack you connect :

GND  -> GND on the ATMEGA

TIP -> pin 2 on the ATMEGA

MIDDLE - > pin 3 on the ATMEGA

Thats the basic setup and now you can use a paddle and the Iambic A or Iambic B setting on the https://hamradio.solutions/vband/

If you want to use your own keyer then you have to connect :

GND  -> GND on the ATMEGA

TIP -> pin 2 on the ATMEGA

pin 4  on the ATMEGA - > GND on the ATMEGA

Now you can use your own electronic keyer or any manual keyer and you have to chose straight key / bug / cottie in the settings on https://hamradio.solutions/vband/

Here you find the arduino sketch /sites/default/files/hamradio_solutions_interface.ino RIGHT CLICK and SAVE AS.

After uploading the pc will find your interface and you just have to place your mouse pointer in the window on https://hamradio.solutions/vband/ and there you go.

Happy CW on the internet.

// in library manager search for "keyboard" and install library

// If you do want to use paddles dont connetc MODE_PIN to GND.

// If you want to use your own keyer connect MODE_PIN to GND

// Remember to set the settings on https://hamradio.solutions/vband/

// Enjoy your internet Morse
