[arm-allstar] Baofeng 888 and URI

[Doug Crompton]

Dan,

 It sounds like you might have the COS phase wrong it needs to be USB not
USBINVERT in  simpleusb-tune-menu. See below for an easy way to check.

Also make sure you selected simplex NOT duplex in the setup. If you connect
a simplex radio up to Allstar and have duplex selected it thinks it can
transmit and receive at the same time and with a single transceiver it
cannot! Symptoms are what you are seeing. You transmit the node radio
receives and then immediately goes into transmit.

To change it select item 9 - bash shell in the admin menu and type
node-config.sh at the prompt. Run through the setup again (prior settings
are default so you can just hit return through them) when you come to the
question for duplex setting select 1 and continue through to the end.

The simpleusb-tune-menu has a view (select V) option that displays the COS
status. It should show keyed when you transmit from another radio to the
888. If it is the opposite select J to toggle the COS and select V again to
see if it is working correctly.

I hope that helps.
