Thread-topic: JT9 Coding?

Hello Marcus,

 

" I recently missed the JT9 activity night, mostly due to the lack of a linear MF transmitter"

I assume that with "linear MF transmitter" you mean a transverter from HF to 472kHz

But just to avoid any confusion: JT9 does not require a linear amplification as it is FSK (similar to WSPR).

Onderwerp: LF: JT9 Coding?

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,

Markus (DF6NM)

"If you have a BPSK-capable beacon which uses an EEPROM to store its

message, WOLF can generate a binary file suitable for programming the

device.
