Via internet I bought a SG1005 DDS signalgenerator.
It produces a sinus/tri-angle/block from 0,01Hz to 5MHz in 0,01Hz steps.
It can perfectly drive the GW3UEP 100W 600m PA, for which I intend to
use it.

It's a very cheap device (around €35,00 free shipping fm CN) however it
comes with no diagram or info.
(Everything has it's price!)

On the PCB there is a connection for some sort "communication" with a PC
or whatever, but have no info how to adress/connect it.
The two main chips are STM8S103 and the Altera MAX II EPM240T100C5N.

I Googled very deeply but didn't get that info I required.
Maintarget is to generate WSPR with it.

Does anyone in the group SG1005 device and succeeded to generate the 4
WSPR freqs from it?
