It is programmed via the printer parallel port and the instructions recommend using the supplied program by G4OPE using DOS. (I have a vintage laptop specially for the job). I am now not able to read the DDS PIC16C84 memory anymore although I can program it by first setting all the memory to zero and overwriting with new frequency data. I am unable to tell if the reading problem is with hardware or software. Does anyone have any knowledge of this Hands DDS unit? I would be most interested to find a way to apply data modulation to it. Peter G3LDO
