We recently installed AllStar on an old PC. At present we have a 10 year old Motorola 2M Radius radio connected to the AllStar PC via a custom cable and URI. The radio was tuned by a professional with tuning equipment according to the AllStar instructions. We can RX well and can TX voice well on all radios. Now the problem. Some radios (Yaesu & Icon) can send any DTMF number combination and works flawlessly. However some other radios like the Wouxun can send any number but the number "3" key successfully. For instance *81 gives us the time successfully but 3 used in any string doesn't work. I have modified only two usbradio.conf settings: carrierfrom = usbinvert ctcssfrom = no When I change to: ctcssfrom = dsp we can neither TX or RX. Is there another setting that might help in the usbrdio.conf or any other config file? Can anyone help? It is a young ARC and most members use a Wouxon HT. Thanks in advance, George
