Hi Everyone,

I could really use some help here.  I don’t know if this is a wiring issue or a configuration issue.  It’s probably a configuration issue. 

I’m trying to build a Simplex Node using an HT.  I purchased a URI and made a cable going from the URI to the TRRS Jack on my Vertex VX-150 HT.  It will only transmit or receive.  And this is dependent on whether the “carrierfrom=” setting is set to “usb” or “usbinvert”  When the simpleusb.conf is setup with “carrierfrom=usbinvert”, my HT will transmit call sign and time and stuff like that but it does not recognize any DTMF Commands I send using a different radio on the same frequency.  If it is set to “carrierfrom=usb” my Pi2 will receive DTMF commands but the HT will not transmit anything.  

Thanks In Advance,
