After I try a lot of image I stay with BlackHole-4.7-DM800se-Sim2-SSl84D-20181025. I use a hdd inside and it works.
Only litle issue was the clock. I installed timesync, and sync with ntp. and for some days now it seems to work.
Newer oscam was buggy on conax. I tried to put in libcrypto.so.0.9.8 but not work 100%.
So I use cccam 2.30 insted. I also Installed cccam 2.39 witch seems to work, but use 2.30 as daily driver.
When using the timer, a couple of times the timer/record won't stop, and the box freeze. But I can live with that.
