Make sure your HT is in simplex and not repeater mode (no TX offset)
?
Make sure you have the CTCSS (PL) tone set correctly.
?
Do the following -
?
sudo asl-menu
Allstar Node Setup Menu
Update Node <your node>
Interface Tune CLI
?
Make sure item j) is set to 'no'
?
Select V)
Key the HT and see if COS shows 'KEYED'
?
Go back to Node settings and select 6) Expert configuration Menu then 1 Edit rpt.conf file
?
Scrool down using the down arrow key until you see this
?
?
Verify duplex = 1.? If not set it to 1
?
Use <ctrl>X to exit and Y to save if you changed duplex to 1
?
Use R) to restart asterisk after any changes
?
Hopefully something in the above has fixed your problem.
