PA PTT on TRIO (16) to the KEYIN jack on your PA as well as PA ALC jack on TRIO (15) to the ALC output on your amplifier if it is required by power amplifier manufacturer. Please refer to your power amplifier manual. - Page 7 Ground the controller case using the grounding stud (24) to the central ground point in your shack. At this point, you can power the TRIO on by rear power switch. Keep transceivers and the amplifier turned off and prepare basic menu settings.

Page 8: Initial Menu Settings
Power amplifier communication has to be set to Icom CI-V as TRIO looks for the amplifier as an Icom transceiver. Next menu M22 allows to set CI-V address of such simulated Icom transceiver. - Page 9 © 2025 All rights reserved M23: PA PTT TAIL Sets how long will TRIO keep amplifier keyed after the PTT from the radio is released. To avoid hot switching, it is good to keep at least default 30ms delay, as some transceivers drop PTT output prematurely while RF is still present on its antenna connector.
