This page is a collection of signals used by the amateur service (AS) and amateur satellite service (ASS). The goal is to create (A) IQ-recordings of each signal with known levels and/or (B) methods to generate signals on given frequencies with known levels.
One step during sharing studies is to examine the static case (Transmitter interference vs. Victim receiver). To perform sharing studies it is necessary to be able to play back all possible signals with known levels on affected frequencies (transmitter interference) and expose them to the receiver (victim receiver). Harmful interference is to be avoided and depends in the static case on the signal, frequency and level.
