What is LEILA?
LEILA stands for “LEIstungs Limit Anzeige”. Translated, it means “Power Limit Indicator”. It is an uplink power limiting program that ensures that you are not putting a signal into the bird on using U/S (70cm up and 2.4 gig down) that would result in you being any louder than 8 dB BELOW the Middle Beacon (2401.323 approximately). If you try to transmit at a power level that would result in you exceeding this threshold, Leila will warn you briefly with an audible “Siren” on your frequency. If you do not IMMEDIATELY reduce uplink (transmit) power on 70cm, Leila will “notch” you out. At that time, you have to stop talking/transmitting, reduce power and start again. Caveats: • Leila has not been turned on for L band uplink. It is only being used on U band (70cm). • Leila false alarms due to ground radar at times. If your signal is 8 dB or more below the beacon, you’re ok. • Tricksters have recorded Leila and sometimes play it back on top of you for their entertainment. This is rare, but it
