`-preemphasis` - you can pass either `us` or `22`, us will give 75μs and 22μs (why is 22 here? i dunno ask sdr++ creator why he also added 22)<br>
`-af` - same as pifmadv<br>
`-rdsvolume` - rds volume, so how many times is the rds "louder"<br>
`-pilotvolume` - pilot volume<br>
`-pilotvolume` - pilot volume<br><br>
now you know what you can pass as the args to the program, but theres a pipe still, it wont include the ones in pifmadv or pifmrds:<br>
`PI` - you can change pi code while runtime, useful when you forgot to set a pi code, but you probably won't care about it<br>

# Transmitter Power
By default the Raspberry Pi outputs 4 mA on a gpio pin, but here it gets overriden to max, which is about 16 mA, some apps have a setting to change the power, here is a sheet of the power levels and their correspondent radiated power: (NOTE: RADIATED POWER, NOT ERP, TO HAVE THE EXACT TX POWER OF A TRANSMITTER, THE ANTENNA EFFIECENCY AND GAIN WOULD NEED TO BE COUNTED IN THE CALCULATION)
##### 0 = 6.6 mW
##### 1 = 13.2 mW
##### 2 = 19.8 mW
##### 3 = 26.4 mW
##### 4 = 33.0 mW
##### 5 = 39.6 mW
##### 6 = 46.2 mW
##### 7 = 52.8 mW
<br>**0 = 6.6 mW**

milliwatt, not to be confused with megawatt, if it would be megawatts then your antenna, pi, power supply and the surrondings would dissapear
# To continue
**rpitx2** is a generic RF transmitter. There is a lot of modulation to do with it and also documentation to make all that easy to contribute. This will be the next step ! Feel free to inspect scripts, change parameters (frequencies, audio input, pictures...).
