Dear.

I have a local ACID config connected with a Motorola GM300 and URI


I am using the follow cable:

URI (USB Radio Interface) to Motorola
Maxtrac, GM300 or M120 16 Pin Repeater

I am trying to doing PTT from a Zoiper Softphone to handy device, but not works (*99), i am follow the next howto:

http://allstarnode.com/viewtopic.php?f=5&t=67

But *99 not works for me.

My usbradio.conf:

[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

                        ; please refer to the howto for the procedure to do this.

duplex=2                ; Full Duplex


I hope you could tell me how i can do or what is the best config for usbradio.conf, URI and Motorola GM300?

I hope any idea.

Fernando.
