The App_rpt default is a duplex value of 2 (full duplex) even though it might not state that in rpt .conf. This seems to be the situation for new default files created by the ACID install process.
If the config files are downloded from the Allstar server then I think it sets a duplex value in the RPT.conf based on what you set up the server to be on the website.

So if you connect a simplex radio witht he acid default files, you will need to either add the line in the node stanza duplex = 0 in rot.conf,  and you also must state the duplex setting to 0 in the usbradio.conf file as well.

see below:

In rpt.conf:

[1234]                    ; Change this to your assigned node number

rxchannel=Radio/usb1234
duplex=0                ; set to half duplex

and in usbradio.conf:

[usb1234]

hdwtype=0    
rxboost=0
txboost=1
;rxctcssrelax=1
;txctcssdefault=131.8
;rxctcssfreqs=131.8
;txctcssfreqs=131.8
;rxctcssoverride=0
carrierfrom=usbinvert
ctcssfrom=no
rxdemod=speaker
txprelim=no
txlimonly=no
txtoctype=phase
txmixa=voice
txmixb=no
invertptt=0
duplex=0            ; set this to 0 for half duplex for simplex radios, set to 1 for repeater full duplex
rxondelay=0
rxnoisefiltype=0
eeprom=0

Wade,

  You  mentioned you set all duplex=0  then you said you were not able to find the rpt.conf file.  There is a duplex=  in that file in the node section that needs to be set to either 0 - simplex, no telementry or courtesy tones or 1 - simplex, with telemeter and courtesy tones. If this is not set to simplex and you are using a single transceiver the COS/COR or carrier/signal detect will key the PTT and you will have a race condition. The default is duplex=2 which is the commonly used value for repeaters.

rpt.conf is (should be) in the /etc/asterisk directory.  If for some reason it is not there look for a sample rpt.conf in /usr/src/astsrc/asterisk/configs/

I am not sure what percentage of users configure as repeaters vs. simplex nodes but maybe it would be a good idea to default this value to 0  or 1 as so many including myself get burnt by this. Also there should be a sentence about this in the quick install instructions.

My radio that is hooked up to my AllStar adapter keeps oscillating between TX & RX non stop. I have set every instance of duplex I could find to Duplex=0. I have also set carrierfrom=usb. This radio is a Radius UHF Mobile. I have double checked the wiring connections and all is good.
