Re: LF: JT9 Coding?

Hello Markus,

You can use your normal transmitter, like for WSPR. A linear transmitter is not needed for JT9 because it is FSK.

While we’re at it…  I recently missed the JT9 activity night, mostly due to the lack of a linear MF transmitter. For WSPR, I’ve used a commandline tool (wsprcode.exe, or wspr.exe with -tx option) to encode a message to a file. This is then read by a little homemade program (ddswspr.exe), which feeds an AD9850 DDS module through the serial port.

 

Does anyone know whether a similar encoding option exists for JT9?

 

Best 73,
