BOM for Portable APRS Display

K2MTS Portable APRS Display

The goal here is to create a small, portable APRS monitoring station for use in public service and emergency events. The components chosen here can be powered off of a 12VDC supply provided by a vehicle, battery, or conventional desktop power supply. Most of the components are affordable, and some of them we may already have on hand.

Mockup of Possible Configuration

Radio

BaoFeng UV-3R PLUS
Perhaps the club or a member is willing to donate an older HT that can be used for this purpose.

A cable will need to be built to interface with the radio and TNC-Pi.
