Hello,
we have developed new firmware and software for checking one possible reason for the problem.
It is identical to official 2.5.2 but it has check test whether the unit is running from Backup oscillator or External oscillator.
If backup is used, you will see it as the first event in the Spirit flight log.
You will just need to flash this firmware:

http://spirit-system.com/dl/settings/sp ... -win32.exeCould you please try to install this software and firmware?
It can be tested in minute. This can help us to find why you are having connection problems.
Are you using the USB interface right?
Do you think you could disconnect your receiver please?
So it is powered off. This can help to find if something is causing issue there.
If not, then you can at least try to not power your radio on. During testing you can leave it Off.
