Comment:
This is something that looks not too difficult to implement, although it
needs a database schema update to store the LNA setting.
I have done comparative testing with "LNA off" and "LNA on" with two
different DVB-T2 tuners, a MyGica T230 USB stick and a Digital Devices
PCIe card.
On both tuners there is no difference whatsoever between "LNA off" and
"LNA on" as shown in the Signal/Noise and Signal Strength values in the
mythtv-setup SCANNING page.
The question is whether implementing this will make a difference for
anybody.
If there are tuners who are documented to have an LNA then please add them
to this ticket.
For those willing to test their DVB-T2 tuner, the patch that I used to
test this, 20191217-lna-on-off.patch is attached.
