[F4GCB]

Hello the TX136/500 builders,

This new unofficial version 1.11 gives the following changes :

- FST4W mode added : http://physics.princeton.edu/pulsar/k1j ... _Start.pdf
- Harmonization of timeslots control



Having no TX500 this software has been validated on TX136.
If you update with this version don’t forget that the calibration and configuration values will be reset. For the ones who will try it, thanks in advance for your feedback.

And as usual for our Japanese friends, here is the version 1.11j which limits the RF power according to the portable regulation in Japan.

hello patrick
I just tested the FST4W mode with juma TX500 and TX136.
I think there are no tones transmitted at different speeds.
the other modes are ok.
thank you for your help

Hi Hubert,

A GREAT THANK YOU for your feedback.

I found the bug. The frequency offsets that correspond to the 4 tones are not correctly initialized at TX startup.
On the other hand, when you change the speed FST4W the initialization is generated and the transmission is correct. This explains why I was able to obtain a good operation during my tests.

I'm preparing a new corrected version
