Re: Overdriven P25 audio

I'm running "in production" a DMR<>P25 bridge long time. Beware, there are two ways (DMR>P25 and P25>DMR) you need to adjust.:
Here my settings:
analog_bridge DMR:
usrpAudio = AUDIO_USE_GAIN               ; Audio to ASL (AUDIO_UNITY, AUDIO_USE_AGC, AUDIO_USE_GAIN)
usrpGain = 1.0                           ; Gain (in db) of the AGC filter
tlvAudio = AUDIO_USE_GAIN               ; Audio from ASL (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF)
tlvGain = 0.6                           ; Gain factor of audio from ASL (0.0-1.0)

analog_bridge P25:
usrpAudio = AUDIO_USE_GAIN               ; Audio to ASL (AUDIO_UNITY, AUDIO_USE_AGC, AUDIO_USE_GAIN)
usrpGain = 1.0                           ; Gain (in db) of the AGC filter
tlvAudio = AUDIO_USE_GAIN               ; Audio from ASL (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF)
tlvGain = 1.0                           ; Gain factor of audio from ASL (0.0-1.0)

WIth this setup all is ok, the audio level are good and acceptable.
