Hello,
I am getting in contact with RoIP.
We are using the ACID install with DMK URI to connect a half duplex radio
without COR line. So we have connected PTT (pin1), GND (pin20) , MIC_AC(pin
21) and LEFT_AC (pin 22).
We have also installed the iaxrpt client and the voice is received in a
remote radio perfectly. But we have the problem in the way back. If you
speak from the remote radio, the voice signal arrived at the LEFT_AC of URI
but if it is not processing. Nothing is listened in the iaxrpt client.
I had tried to comments the txctssdefault,rxctcssfreqs and txctcssfreqs
because i have introduced ctcssfrom=no and also i invert the txmixa and
txmixb settings but it didn´t work.
The usbradio.conf looks like this:
;
; Usbradio channel driver Configuration File
;
[general]
[usb]
hdwtype=0 ; Leave this set to 0 for USB sound fobs modified using
; the instructions from usbfob.pdf. Use a setting of
; 1 is for Dingotel/Sph interfaces.
rxboost=0 ; 0 = 20db attenuator inserted, 1= 20db attenuator removed
; Set to 1 for additonal gain if using a low-level receiver output
rxctcssrelax=1 ; reduce talkoff from radios w/o CTCSS Tx HPF
; Do not change this, leave this as a 1
;txctcssdefault=100.0 ; default tx ctcss freq, any frequency permitted
;rxctcssfreqs=100.0 ; rx ctcss freqs in floating point. must be in table
;txctcssfreqs=100.0 ; tx ctcss freqs, any frequency permitted
;rxctcssoverride=0 ; Set to 1 or yes to start out in carrier squelch mode
carrierfrom=vox ; no,usb,usbinvert,dsp,vox
; no - no carrier detection at all
; usb - from the COR line on the modified USB sound fob
; usbinvert - from the inverted COR line on the modified USB sound fob
; dsp - from RX noise using dsp techniques
; vox - voice activated from RX audio
ctcssfrom=no ; no,usb,dsp
; no - CTCSS decoding, system will be carrier squelch
; usb - CTCSS decoding using input from USB FOB
; (currently not supported)
; dsp - CTCSS decoding using RX audio in DSP.
; rxdemod option must be set to flat for this to work.
rxdemod=speaker ; input type from radio: no,speaker,flat
; no - RX audio input not used
; flat - Use RX audio from discriminator (before de-emphasis)
; speaker - use de-emphasized audio
txprelim=no ; Audio processing on left output channel: no,yes
; no - Audio is not pre-emphasized and limited.
; Suitable for use on a microphone input
; yes - Audio is pre-emphasized and limited.
; Suitable for direct connection to an FM modulator
txlimonly=yes ; Audio limiting with no pre-emphasis on output channel:
no,yes
; no - Audio is not limited.
; yes - Audio is limited.
; Suitable for transmitters with no limiting but with pre-emphasis.
;txtoctype=notone ; Transmit tone control type: no,phase,notone
; no - CTCSS tone encoding with no hang time
; phase - encode CTCSS and reverse phase
; AKA ("reverse burst") before unkeying TX
; notone - encode CTCSS and stop sending tone before unkeying TX
; AKA ("chicken burst")
txmixa=no ; Left channel output: no,voice,tone,composite,auxvoice
; no - Do not output anything
; voice - output voice only
; tone - CTCSS tone only
; composite - voice and tone
; auxvoice - auxiliary voice output at headphone level for monitoring
txmixb=voice ; Right channel output: no,voice,tone,composite, auxvoice
; See txmixa above.
invertptt=0 ; Invert PTT 0 = ground to transmit, 1 = open to transmit
; This is the collector lead of the 2n4401 on the modified
; usb sound fob.
; please refer to the howto for the procedure to do this.
duplex=0 ; Half Duplex
rxondelay=20 ; Uncomment and/or adjust for simplex nodes to eliminate "Ping
Ponging"
; or "Relay Racing".
; A positive value here will instruct the usbradio driver to ignore the
; COR line for a specified number of 20mSec intervals following the
; release of PTT. Use this only on simplex nodes, and leave commented
; out for repeaters or other full duplex nodes.
Can anyone help me and tell me what i am doing wrong?
Thank you.
Regards,
Eva
