I was able to scan the channels with vertical polarization, the mux with horizontal polarization (CH 55) had low signal, so I couldn't test it until now, but today I tried and I have a signal, but only 1 "empty" channel found.

Where is the problem, should I try another offset option?

umm I just read about polarisations & DVB-T
interesting,
I dont know how to answer your question, right now , I dont have access to DVB-T broadcasts at all.
you can try -167 and 167

Thanks, I tried those values already, result is no signal, with offset 0 the result is 0 channels with no signal and 1 "empty" channel - what does it mean? Perhaps it's just low signal, but on the TV with the same antenna it works at the same time.

Full scan found 6 empty channels, those might be the Hungarian channels in MPEG4, but I have no problem with MPEG4 in mux 1, strange...

You can better find exact frequencies and edit terrestrial.ini with notepad because some transponders might have offset , some might not at the same location.

For the polarisation, I think you can simply change the orientation of the antenna (vertical/horizantal position) to get better signal level for the desired polarisation.


empty= empty frequency (scanned but couldn't find anything)

maybe because of weak signal packet losses

I know the exact frequency and I have a signal, but I think the level indicator is not exact.

I know I can change the antenna orientation, but the other muxes are using V pol., so it's not easy, on the other TVs with DVB-T tuner I've got a signal on all muxes, all channels. Anyway, I'll try to do something, but not today, it's too dark to climb on the roof.

maybe the channel is DVB-T2 ? and your tuner only supports DVB-T?

The channels are in DVB-T MPEG2, I am sure, but the signal is lower than others and the tuner is probably not as sensitive as the ones in TV.

Not a bug, problem solved with the new tuner.
