Use -S <dB> for setting RF level or use -S auto for auto level.
When squelch closes, audio is muted. If squelch is closed for some
seconds (depending on network), call is released. (RF loss condition)
The previous loss detection has been removed
The power level is ramped smoothly within 1 ms up or down.
R2000, AMPS and C-Netz turn off power when voice channel is not i use.
C-Netz turns off power between OgK timeslots.
Use function to get samples to be sent to fill audio buffers to a
level. This replaces the function that only shows how much data
is in the buffer.
This way the function itself can control how much data will be
sent.
Paging tones are not created within sound_alsa.c
The audio API is now responsible to switch to paging channel.
In case of SDR, the sdr.c will switch frequency offset.
Sound instance is now called audio instance and uses funcation pointers.
This gives a clean interface to be exchanged with other technologies,
linke SDR.
Connect to the oscillator of the transmitter - good girl!
You need to enable pre emphasis in this case.
Connect to the discriminator of the receiver - good boy!
You need to enable de emphasis in this case.
-W <file.wav> writes a wave file of received audio
-R <file.wav> reads a wave file to feed into decoder
This way you can record a phone and later debug without a phone
and radio equipment.
