Hello everybody,

For people who need accuracy inside their digital radio modes, here is a configuration set for Windows / Linux :

Install NTP program, for Windows user you can use this binary :
https://www.meinbergglobal.com/english/sw/ntp.htm#ntp_stable

For LINUX simply do an « apt-cache search ntp » and install server dameon.
On Windows, configuration is the same ( via ntp.conf, edit in administrator mode your configuration ) :

If you want CRX Purpose an NTP service :

ntp.crx.cloud
ntp2.crx.cloud

You can add these servers  :

server ntp.crx.cloud 
server ntp2.crx.cloud

On Windows you have two shortcuts :

=> Quick NTP Status
=> Edit NTP Configuration

For Windows10, these shortcuts are in :

C:\Users\[YOUR USER]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Meinberg\Network Time Protocol

For LINUX simply do :

# ntpq
And tape :
ntpq> lpeers

Depending your country, you can modulate your NTP servers.
Here CRX is for Europe user’s.

That all, you can use your FT8 mode, now with best accuracy possible !
