ICOM 7100 Go-kit Connections
SRCARES-250_7100Connections – Rev 1.0 Page | 1 AJT-07/18/21
All connection ports in this document are identified with [BRACKETS]. Anything you see in
[BRACKETS] is the name of the actual port on the referenced device. All cables are labeled
identifying the proper port of connection. Each kit includes a PWRgate PG40S to allow the radio to
run off battery power in the event of AC power loss. Please make sure, on any power connections,
that red goes to red and black goes to black, so the polarity of the connections is not flipped.
1. Lay the go kit on a flat surface.
2. Unlock the 4 latches of the go-kit and lift the lid.
3. If you need the manuals, they are located behind the top padding of the go-kit.
4. Remove all pieces of the ICOM-7100 radio from the kit.
a. Please note, if you do not need HF capability, you will not need the antenna tuner or
tuner cable.
