It seems in fact that signal indicator is not reliable.
I have to sometimes reset dvb with:
for I in dvb_usb_af9035 af9033 tda18218 dvb_usb_v2 dvb_core rc_core; do
rmmod $I; done
modprobe dvb-usb-af9035
The antenna signal input is fine, this is at least the point I am sure.

Not sure of that. tzap test seems to show the opposite:
tzap -r TEST
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
reading channels from file '/home/test_r/.tzap/channels.conf'
tuning to 586167000 Hz
video pid 0x0200, audio pid 0x028a

I also took the kaffeine dvb files perfectly working with saa7134 card,
but A918R card does not tune on any channel.
Then, the lack of signal strength stability / front-end problem is may be
the root cause.
Thanks again for your time
