Alphonso:

The original question I answered was about the of COM7. The BBC do not decide what the power of any is, as stated earlier that is a matter for Arqiva, and international agreements. Others here, MikeB and StevensOnln1 have explained the history of why BBC4 is on COM7. If there was available capacity on PSB3 then it is likely that BBC would use it for BBC4 but there is no spare capacity between 7 PM and midnight (or later) so they cannot provide the service they desire via that . Hence having to pay for use of COM7.

Note that COM7 and COM8 are due to cease in the next round of service allocations.

My recommendation for all the Com7/BBC4 HD problems is to use - as I mainly do.
