The schedule is a table printed at the back of the terms and conditions document BR68F. It tells you where and how you may operate. For each band it tells you permitted modes, maximum power output allowed as well as the frequencies defining the edges of the band. You will be provided with a copy of this document during the training course and during the assessment. You should seek to obtain an up to date copy of this document and learn as much of it as possible. When you get your licence you will need to know where you can operate.

Column 1 of the schedule shows us where the foundation licencee may operate.
Column 2 gives the status of the allocation. Secondary status means we must not interfere with those users who have primary status within the band.
Column 3 tells us how much power we may use. Power is usually measured at the antenna terminals. At the higher frequencies, a significant power loss may occur in the feeder connecting the transmitter to the antenna. It is permissible to increase our transmitter power output to compensate for this loss. It is however much better to use a different kind of feeder with a lower loss, since losses in the feeder will affect the received signal too.
Note that for the frequencies 430-432MHz. the maximum power allowed is expressed as 10W erp (effective radiated power). This is not the same as power at the antenna terminals. Effective radiated power erp = power x antenna gain. So, if we were using an antenna with a gain of 4 (6dB) then we must ensure that we do not exceed 2.5W at the antenna terminals, erp = 2.5 x 4 = 10W.
Column 4 tells us which methods of communication we may use. Note that for the foundation licence they are all the same for every band. We will learn more about the different kinds of communication we may use later in the course.
