I am using an AllStar node as a link to a repeater. After much experimentation duplex needs to be zero to keep from oscillating between the repeater and the link so rpt.conf is set to":
"; REPEATER/SIMPLEX NODE SETTINGS
; duplex=0 - Half duplex with no telemetry
; tones or hang time. Special Case: Full
; duplex if linktolink is set to yes.
; This mode is preferred when interfacing
; with an external multiport repeater controller.
Echolink announcement is set to 2:
; Echolink announcement mode
; Default: 1 = Say only node number on echolink
; connects. 2 = say phonetic call sign only on
; echolink connects. 3 = say phonetic call sign
; and node number on echolink connects
and id settings is set to:
But the node never identifies itself.
I am not sure that it is legal for the node to never identify itself.
