I run nodes 2498 and 27333 details as follows
Node: 2498 is off an Alinco DR135MKIII and the radio is in 9600 Baud so
audio is from discriminator and modulator. This works great and the settings
are:
[usb]
; name=usb
; devicenum=2
devstr=2-1
rxmixerset=875
txmixaset=500
txmixbset=500
rxvoiceadj=0.764955
rxctcssadj=0.500000
txctcssadj=50
rxsquelchadj=500
The second node off the same PC node 27333 is off a Yaesu VX2000 and set up
as above to feed flat audio in/ out. The settings have been changed but at
best the audio out is so low only if I have the volume on my receiver at 90%
I can hear the stations Settings are:
[usb1]
; name=usb1
; devicenum=1
devstr=3-2
rxmixerset=400
txmixaset=600
txmixbset=600
rxvoiceadj=1.549599
rxctcssadj=0.506345
txctcssadj=50
rxsquelchadj=750
I have changed the rxmixerset=600 up to 900 with no great increase.
This is the USB settings:
;
; Usbradio channel driver Configuration File a
;
[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=1 ; 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=110.9 ; default tx ctcss freq, any frequency permitted
rxctcssfreqs=110.9 ; rx ctcss freqs in floating point. must be in table
txctcssfreqs=110.9 ; tx ctcss freqs, any frequency permitted
rxctcssoverride=0 ; Set to 1 or yes to start out in carrier squelch mode
carrierfrom=usbinvert ; 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=dsp ; 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=flat ; 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=yes ; 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=composite ; 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=composite ; 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 ; Full 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.
