If timing slips, the averaged power will be out by the amount of slippage.  So, for a 1 second error the total power summed over the window is 4/5, or about 1dB down.   For 2.5s slippage, -3dB
 
BUT..
 
.. this may be only an approximation as windowing is applied so the contribution from the power measured at the middle of the timing window is given a greater weigthing than the measurement at either end.  In this event, slight timing error will introduce even less error.

Andy,
 
Q .. If the  tx is keyed by vox/breakin    will the slight  clipping of the  leading edge of the  beacon  cause time problems ??
reason being  .. if use force 'tx' will miss the  beacon rx windows ??
 
Tnx- G ..
