If you used Auto Tune to set up your Aura this can often pick up signals from one or more nearby transmitters,
this can then cause some problems with recordings being missed.
Check the EPG and see if there are duplicate channels in the 800's.
If there are duplicate channels then this could be the problem and a manual tune is recommended.
First you would need to determine which is the most suitable transmitter to tune to.
Click here, https://www.freeview.co.uk/corporate/detailed-transmitter-information
Enter your postcode and house number, click check.
The next page will give you details of the transmitters broadcasting in your area.
Under Digital Transmitters you will see 'most likely' and 'alternative transmitters'
Assuming your aerial is pointing to the 'most likely' look under the 'N' (on a black background)
to see the Channels/ Multiplexes that transmitter is broadcasting.
Make a note of these numbers, especially the one under BBC B, this is the multiplex carrying the
HD channels.
I would now do a factory reset of the Aura, and an auto tune with the aerial disconnected from the Aura.
Reconnect the aerial.
Now do a Manual Tune of the Aura.
Press the Freeview button on the remote, select Settings and click on
Channel and Broadcast> Manual Channel search.
Click on Channel and from the list select one of the multiplex numbers you noted earlier.
On the Strength and Quality meters make sure these are populated.
Ideally Strength should be between 85- 95%. (100% can cause problems and may need an attenuator
to dial it back).
Quality should be 100%.
Click on Search.
When the search has been completed for that mux press Save.
You will then need to press Manual Search again, enter the next multiplex/ mux number and repeat.
When you manually search for the HD broadcasts you must change the default Transmission from DVB-T to DVB-T2.
All SD channel searches Transmission must be set to DVB-T.
Go through the EPG and make sure there are no duplicate channels in your list.
Set up a recording as a test from the guide, try not to choose a programme that is just about to start
as you may have already missed the signal for the recording to start, try a programme that is starting in
about 5 minutes or more.
