I replaced one Sat to DVB-T2 (now totally 3) but it doesn't work.
The new receiver works on the A & B slots but not on the furthermost one. Not even using just the one receiver work on that slot

When A&B are reserved and C would be needed I'll get error:
No data on transponder Timeout reading PAT

Neither the Manual tuning finds any channels with the C-receiver but for the A&B they are found OK.

The Sat-receiver worked on the C-slot, the new T2 receiver works on the other slots, I've checked the antenna as well.

I'm using the OpenVIX 152. What might be the problem, please?
