Oops :D. Could you please elaborate a bit on this? I don't know what is

the LNB connector you are referring to. Plus, I don't have right now any
voltimeter, but if needed I'll grab one from work tomorrow.


So, as I started playing with my A700 card, I discovered that the 
input-connector on the card, where one attaches the coax-cable to the 
lnb/dish, sent out wrong voltage.

13V / 18V was swapped. So I patched mt312 driver and added the setting 
voltage_inverted to reverse it.
Instead of just guessing what happens it is interesting to just call the 
dvb-apps example app set_voltage and measure what voltage the hw outputs.

Matthias

OK, I don't know exactly what you mean, but I'll try to measure the output voltage of the input connector. I think you mean this, don't you?

BTW, ¿where is the set_voltage app? I have media-tv/linuxtv-dvb-apps package installed and there is nothing with that name...

Regards,
Eduard
