Ham Radio Off-the-Grid "Go Box" and Solar Charging System

rsc

For off-the-grid communications, a radio "Go Box" is sometimes a good option.

In places with no cellular coverage, your only options for communication are radio or satellite.

I chose to build a Go Box using an ICOM IC-2730A mobile transceiver since it can be used as a dual cross band repeater, or a full duplex satellite communications radio.

I also have a 100W solar panel that came with a couple of 12V lamps and a battery charger interface that works well with the Go Box.

I have 2 batteries for the system, a 12V 7.5AH sealed lead battery for most days, and a 12V 20AH LiFePO4 for extended use.

I've used the system for Ham radio winter and summer Field Days for the past two years.

I've even talked to the International Space Station using the Go Box with an Arrow II Dual Band Yagi antenna.

The Go Box still needs some work - I have a few accessories to add, some USB charging ports, and some other 12V charging ports. Stay tuned for updates....
