Simplex conversation (Event Handler)

General

This article describes how you can override the voice-operated duplex (VOX), and set the system in Simplex (Press To Talk) mode.

Software requirement: AMC 10.52 or newer.

Whole Exchange in Simplex Mode

This event will set the whole exchange in simplex (Press To Talk) mode (will also work in AlphaNet).

In AlphaPro, go to Exchange and System -> Events, press Insert and create the following event:

Event that sets the whole exchange in simplex mode

• Owner: UDP 8 (All stations)
• Event Type: Conversation Outgoing
• When Change To: ON
• When Related To: All
• Action: @U%2.nod $SIMP L%2.dir U0 U1

Initial speech direction will be from B-subscriber towards A-subscriber.

If the Simplex mode should not apply to the whole exchange, but to a single station or a limited group of stations only, simply change the owner of the event to that single station, or include the relevant stations in an UDP group and set this UDP group as event owner.
