To be 100% sure if a system works absolute stable you just have to provoke it by saying: this system is working 100% stable... And wait what happens.. I did that yesterday and today after weeks i had to restart WSPR and reset the network connection. The time was out of sync and after reseting the w-lan interface the WSPR timer was struck. For the first time as far i can remember.. This very bold statement really wakes up mystic powers in equipment..
