Hi,
I have been searching for how to encode the 50 bit payload message when using a 6 digit locator, but have not found the specific algorithm. I can find general information that the call is hashed to 15 bits etc.
I am coding an Arduino to build a small WSPR beacon. The code works well with the standard message, but I would like to extend(!) it to cover also a 6 digit locator.
Can anyone point me to the protocol specification? What hash algorithm is used?
Tomas
