Manual tuning is not complicated.
Not for you or I maybe, but the average user?
Plenty of average users have performed manual tuning; I think it is quicker than automatic tuning once you understand it. However I do accept that manual tuning should not be necessary for all but the unusual cases.
Yes but the point is why is there such a SIGNAL QUALITY difference? That is why the Aura SD channels are breaking up. Lets not go down a manual tuning rabbit hole
I’d like to try one manual tuning just to compare. Could someone help with how you do it please?
Doing it is simple. To help you you need to provide the information I asked for previously in your post that admitted you knew you were receiving from more than one transmitter. And the followed that up with a post about how it must be the box as it works on your TV's on the same aerial.
You should find that you have duplicate channels on com 6 with numbers over 800.
A good start would be to tune to these in turn and make a note of the UHF channels used for each compared to those stored with the lower channel numbers and compare the signal info for both.
That should help to decide which transmitter gives you the best reception for your location. Bear in mind if you used autotune during a high pressure uplift you may be getting channels that under normal conditions are much weaker, and look at the signal test values. You should finish up with a table of best reception and UHF carrier used.
In some cases you might be able to temporarily use a attenuator set to a value that ignores the unwanted weaker channels and remove it after a autotune.
Autotune simply starts at the lowest UHF channel and works up to the highest. Once it finds a channel it allocates the lower LCN. If it finds a second it adds it again with LCN over 8oo incrementing eack lcn by 1 for each new one found.
Only if the best transmitter highest mux frequency is lower than the first of the unwanted second is it safe to delete the over 800's.
No problem on a TV. A PVR requires the broadcaster to transmit recording codes (CRIDS). So more than one recording set could find two recordings from different transmitters to schedule. If the unwanted ones or not in the epg the issue never arises.
