[arm-allstar] Interfacing with Icom UR8050

[Matt]

I'm using a modified USB fob with an Icom UR8050 repeater. Everything 
seems to be working as it should from the node side but I have a small 
issue what I connect the usb fob to the repeater.

It seems to muffle/distort the repeater tx audio. For example, If I 
connect via the node and TX then the repeater goes into TX mode and 
transmits the audio received from the node just fine. However, the 
repeater courtesy tone is distorted when the audio transmission ends. 
Another example is when there is no connections to the node and the 
repeater sends it's ID. The repeater goes into TX and sends the Morse ID 
but it sounds distorted and very quite. If I unplug the USB fob then the 
repeater works just fine.

Just to clarify, I'm using the built in repeater logic to control the RF 
side of things and I don't want the node to send any tones or ID. I just 
want it to send repeater audio out to the AllStar network and send 
Allstar audio to the repeater.

My connection like like this...

Fob TX Audio - Repeater LI (Modulation signal input with 300-3000Hz 
6dB/oct emphasis)
Fob Ground - Repeater GND
Fob RX Audio - Repeater LO (Detected signal output with 300-3000Hz 
6dB/oct de-emphasis)
Fob PTT - Repeater EXT PTT (External PPT input. Connect to ground to TX)
Fob COS - Repeater BUSY (Becomes high impedance while receiving)

I have duplex=2 in my rpt.conf and duplex=1 in my simpleusb.conf is that 
correct?
