...i checked some files from the slow_WSPR tool. I think i would be able
to solve the problem. Maybe Markus likes to confirm that this could work
(getting a factor 2 in the frequency shift)?
Chris, it would then be worth to try the normal tool first.

Hello Chris,
For a clever person it is very easy :-)
It will depend on which way you want to generate WSPR.
Here, for example, i have a Raspi which generates my WSPR (2) for MF.
I modified the c source code so that the frequency is 4 times higher
and the frequency shift is 4 times higher too. In my PA, probably like
in yours, there is a frequency divider using CD4013 ICs which
reproduce the desired frequency and frequency shift. Of course this
can be done with a factor 2 too.
For Windows solutions, there is DF6NMs tool for slow WSPR which works
very reliable here, for WSPR-2 and WSPR-15. I'm sure this can be
modified for twice the frequency shift but then you will need an
upconverter to convert it to LF or MF...

Hello LF,
A naive question re WSPR15 please? Assuming the source code is
available how hard would it be for a clever person to add X2
functionality to it? Thanks.
