Hi Bryce,

Just to remember for the history:

AO40 uses LEILA wich continuously scanned the Mode-S
passband and superimposed an intermitted sound like a horn
over those uplink signal wich peaks where more than 10 dB
belove the beacon level.

In addition LEILA suppressed several dB and distorted those
uplink signals that do not reduced immediately their EIRP

73" de
