Then you need to manually tune to the preferred transmitter. Your User Manual will tell you how rto do that and use the Digital UK Coverage Checker to look up which channels to tune to, see Digital UK - Coverage checker

as the SD channels are all still working then so are the HD services. Check your aerial system and that you are tuned to the correct transmitter.

Your location is shown as being very poor for Freeview reception, see Coverage Checker - Detailed View The alternative is to use Freesat.

If you are getting any chennels on your Sky box then you should be getting them all. The dish is aimed at the Astra satellites and receives all the signals en masse. So check the box is working correctly.

Wes:
It is not possible to make any difference to a perfectly natural phenomenon such as the inversion effect. It is how the atmosphere works and is entirely natural and cannot be changed. It has existed for many millenia and became noticable when we humans started using frequencies that are affected by the phenomenon. Think back to the fading that affects transmissions in the medium wave at around 208 metres, as used by Radio Luxembourg.
Satelite reception also suffers from natural effects that reduce the received signal strength when the air is moist, such as fog, rain, snow, etc. Again there is nothing that can be done to change a naturally occuring event.

Maccers:
The transmitter does not suddenly stop transmitting just one of the programmes within a multiplex, so there must be a poor connection within your aerial system, which is a well known cause of such problems. That can give rise to a signal level that is marginally weak so check what signal strengths are shown on your TV, the ideal is between 60% and 85%. Less or more will give rise to intermittent loss of some channels. So check all the connections and unpliug any coaxial plugs and sockets, refit them and check again.

I wonder where you got those quotes from as they do not apear in any of my postings - I am careful not to be so deliberately rude!
Your understanding is different from mine, so please stop trying to change physics.

William Hill:
The HD multiplex was not 'down' at all as no one else has reported any loss of those programmes. Please check the signa;l strengths of the affected multiplexes for the transmitter, you need at least 60% strength and ideally not more that 85%.
It is worth noting that the multiples carrying those HD services also carries some of the SD services.

P Morris:
There are over 1100 transmitters around the UK, some are 'full' service and others are a 'light' service. 30 of the 'full' service transmitters also carry the COM7 and COM8 services. If you receive from a 'light' transmitter, as is the case with the Stroud transmitter, then you are very unlikely to get any more channels unless the commercial programme suppliers decide to have their programmes carried by that transmitter. That is a purely commercial choice they make as it costs them substantial sums to have their programmes broadcast from any transmitter.

The BBCB multiplex is already HD and has been for some years. There are no COM7 or COM8 transmissions from Midhurst and will never be as they are temporary services likely to finish in around 2022.
