Here are a couple of plots of the jamming currently in place on 10775H on 13E. What you see depends on how you look at it. The narrow bandwidth plot makes the carrier look very high. However, measuring the relative power shows that the carrier is about the same level as the wanted signal. These figures are relative as the system is not calibrated end to end:
Carrier level = -51dBm
Wanted signal power -124dBm/Hz
Wanted signal in 28MHz = -124 + 74dBm = 51dBm i.e. a similar level to the carrier
