[arm-allstar] Link Radio COS/CTCSS stuck active issue

[Mike Sullivan]

Node Configuration: Our club has a repeater on a CAT-250 controller
connected to a RIM-Lite, which is used on our public club node There is a
second RIM-Lite connected to a Motorola link radio to another radio system
for a weekly net, operating as a private node. Both nodes are configured
and working, and I have drawn a rudimentary drawing attached which shows
this configuration.

Repeater is set up duplex=0 and linktolink=yes since it is tied to the
controller, and works as it should with no problem. There is no issue on
this side at all related to my problem.

When the link radio is set up duplex=0, linktolink=no, the node receives,
and will transmit if the channel is clear, but it will not key up until
COS/CTCSS is clear. Supermon does show the node active, but it does not key
up the radio.

When the link radio is set up duplex=0, linktolink=yes, the node will
transmit over a signal being received. However, when it does this, the
COS/CTCSS remains active during the transmission, and does not clear until
after the transmission is complete and the other system drops. It does pass
audio, but if this happens while entering a DTMF command on the remote
system (I have one set up for manual control of the link) the node will
hang up in both Receive and Transmit until Allstar is restarted.

I don't know if this is a behavior issue with the radio's programming, or a
glitch in SimpleUSB, or what the issue is. I'm asking to see if anyone else
has experienced this issue before. It is very frustrating.. in the first
configuration, traffic is missed if someone does not allow the link to
fully drop. In the second configuration, it does what I need, but the stuck
COS causes lockups.
