[Raspberrypi+RTL2832] Signal quality on Panasonic TV

Post by xtrem007 » Mon Feb 11, 2019 7:54 pm

Hi,
I installed a minisatip on Raspberrypi Zero W (Raspbian Stretch) and connected the Realtek RTL2832 DVB-T tuner to it.
Panasonic TV CX750 working as SAT> IP client always shows "Signal quality = 10%" and "Signal strength = 0%" regardless of the antenna settings and the selected mux/channel.
Is this a tuner problem or something else?

it seems the value that was read from the driver is too small for SNR. If you think the value returned is actually real, you can use: -M *:1-16.

But I see regardless of the signal you do have data.

I think the signal strength value returned from the driver is not real.
ProgDVB also show incorrect strength and quality of the signal.
Adding the -M *: 1 to 16 parameter doesn't change anything.
Is there any Realtek RTL2832 driver for Raspbian that returns correct signal values?

Can you try a newer kernel ? I see it is using the old api, maybe the new api wouls work better?
