Constructor & Destructor Documentation

◆ FGRadioTransmission()

FGRadioTransmission::FGRadioTransmission ( )

AM transmitter power in dBm. Typical output powers for ATC ground equipment, VHF-UHF: 40 dBm - 10 W (ground, clearance) 44 dBm - 20 W (tower) 47 dBm - 50 W (center, sectors) 50 dBm - 100 W (center, sectors) 53 dBm - 200 W (sectors, on directional arrays)

◆ receiveATC()

void FGRadioTransmission::receiveATC ( SGGeod tx_pos,
double freq,
std::string text,
int transmission_type )

for low SNR values need a way to make the conversation hard to understand but audible in the real world, the receiver AGC fails to capture the slope and the signal, due to being amplitude modulated, decreases volume after demodulation the workaround below is more akin to what would happen on a FM transmission therefore the correct way would be to work on the volume
