HAM Radio Service Availability

Introduction

　PRISM’s downlink has been received among amateur radio operators since the launch of PRISM. This HAM Radio Service allows amateur radio operators to uplink messages to PRISM as well as downlink messages from PRISM. In other words, amateur radio operators can use PRISM as a message box.

Overview

　In this HAM Radio Service, you can write messages onto PRISM’s on-board memory via FM packets uplink. Also you can command PRISM to downlink the stored messages in FM packets.

The followings are three commands you can use.
