Setting ATPC
This procedure is based on the prevailing path conditions being typical during the
setup procedure, that is, not subject to rain fade or other fade conditions and assumes
the Target Fade Margin is the primary driver for establishing the settings.
The objective is to check that Remote Fade Margin and the Detected Tx Power are
within +/- 3 dB of the planned figures for the link, and that there is appropriate Tx
Power headroom for correct ATPC operation.

which will allow head room for the local Tx power, while
ensuring an adequate fade margin.
