My TV will revert to channel 800 instead of 101 for BBC 1 SW HD. Why?
PL24 2DB Loft aerial.
TV retuned many times. 101 comes, then when TV off overnight, reverts to channel 800.
I also have a Humax Freeview Play recorder box which has the same problem. This tunes to channel 802.

David Adams:
This sort of issue is usually caused by the set/box memory either getting "muddled" or you were receiving more than one transmitter when you reuned.
The best way to resolve this is to clear the memory and then perform a manual retune BUT note -
There has been some quite variable weather related Tropospheric Ducting in recent days which can affect reception because of interference being received from more distant transmitters in Europe or the UK - not all multiplexes are necessarily affected, but this isn't normally sustained for any lengthy periods, but if present during automatic retunes can cause the sort of problem you've seen especially with multiple retunes!
The usual way to clear memory is to unplug the aerial and start an automatic retune (you can cancel it once started) so no channels are found. With your Humax beware it may also clear any scheduled recording which you'll have to reset.
IF this method doesn't clear memory, refer to the set/box's manual.
In normal circumstances you are predicted to be able to receive more than one transmitter, and this could be "enhanced" in current conditions so that even with the transmitters in different directions your aerial may still receive the signals on "side-lobes".
The best way to ensure that you tune correctly is to manual tune the UHF channels -
For each of the 6 multiplexes (groups of channels) -
The UHF channels for Caradon Hill are C28, C25, C22, C21, C24, C27 - that's In the multiplex order -PSBs1/BBCA, PSB2/D3&4, PSB3/BBCB HD, COM4/SDN, COM5/ArqA, COM6/ArqB
