Short Description Lentus is an extremely slow QRP mode developed by Patrick Lindecker F6CTE used to transmit QRP's at very low power. Each 43-character (75 bit) transmission takes roughly 5 minutes to transmit across 32 possible tones in a tight 25 Hz bandwidth.

Lentus is an extremely slow QRPIn amateur radio, QRP operation refers to transmitting at reduced power while attempting to maximize one's effective range. mode developed by Patrick Lindecker F6CTE used to transmit QRPIn amateur radio, QRP operation refers to transmitting at reduced power while attempting to maximize one's effective range.'s at very low power. Each 43-character (75 bit) transmission takes roughly 5 minutes to transmit across 32 possible tones in a tight 25 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). bandwidth.

Lentus has an extremely high sensitivity rating (down to a minimum S/N ratio of -34 dBThe decibel (dB) is a logarithmic unit used to express the ratio of two values of a physical quantity, here the strength of a received signal., with first decoding at -36.5 dBThe decibel (dB) is a logarithmic unit used to express the ratio of two values of a physical quantity, here the strength of a received signal.), able to decode even when under the noise floor.Lentus is aimed for usage on LFLow Frequency (30-300 kHz), MFMedium Frequency (300-3000 kHz) and HFHigh Frequency (3-30 MHz) (up to 14 MHzMegaHertz (MHz) 10^6 Hz).
