to tell the difference the amplifier is for DVB-T2, DVB-C is disabled
in windows because it's not reliable.
Technically the chip supports it but the LNA decreases the quality.
There are already some other PCI boards
out there with that chip which do not use that LNA which should have a
better performance with that Sony chip.
Is it possible to work around this by disabling the lna or is the
quality decreased permanently as part of the hardware design,
independently of whether the lna is enabled or not ?
I searched the linux-media list and it seems that an lna option was
discussed as a module parameter, but modinfo for the module I use [1]
(using the media_build git repository) doesn't show a lna parameter.
Can the lna be disabled in another way ?
no, otherwise it would be sold as full hybrid device. DVB-T2 is weak
that's why it was added.
Failing DVB-C would increase the device return rate, that's why it is
sold as DVB-T2 only.
How the others have resolved that problem? Is that signal strength only
issue when TDA18271 tuner is used?
