[App_rpt-users] Simpleusb problem

Sat Jul 21 21:30:51 UTC 2012

Hi Ryan,

I wonder if you've tried the version I sent you? I'm wondering if this issue 
comes down to a syntax problem, etc? For example, I didn't see a [general] 
line in your simpleusb.conf. Also, make sure that usbradio.conf does not 
exist in /etc/asterisk.

I figured I'd also post this to the group, in case anyone wanted to have a 
'template' file for usbradio.conf or simpleusb.conf. As you know, I'm a big 
fan of SimpleUSB. It makes it possible for node owners to do more with a 
less powerful PC, provided that you use a COS line from the receiver, and 
don't use software-based PL squelch. Like running 3 or 4 RF nodes on a 
Pentium 3 PC!

Note that I've made a couple of changes here, such as txmixa=voice and 
txmixb=no instead of having both at no. I'm thinking that the software will 
default both to
voice or composite if mixa and mixb=no. I use this same setup on my nodes, 
and both audio channels combined result in a much too high audio level.

I've also commented out the IRLP board support, but it is shown for anyone 
that might need or want it. I've also included comments that show what each 
command does. This helps me out a great deal when trying to troubleshoot or 
change settings on different nodes.

[usb27539]

; IRLP board support
; pp3 = ptt ; out0, out1 or ptt
; pp12 = cor
; pp4 = out0 ; pins 4,5,6 are AUX 1,2,3, default off
; pp5 = out0
; pp6 = out0

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
txboost=0
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=usbinvert ; no,usb,usbinvert,dsp,vox,pp,ppinvert
; 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
; pp - parallel port (active high)
; ppinvert - parallel port (active low) Motorola via PNP/NPN

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=no ; 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=no ; 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=voice ; 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=no ; 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=1 ; Full Duplex=1, Half Duplex=0
rxondelay=0 ; 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.
rxnoisefiltype=0
eeprom=0 ; EEprom installed on USB Fob
