Internet Remote Operation

Internet Remote

Operation

by Wojtek (Berni) Bernasinski, G0IDA, SP5GU

The technological advances in computing and microcontrollers that

have taken place in the last few years have resulted in it being easier

than it has ever been to set up and operate a remote station. This

practice would appeal mainly to those who have limited real estate at

home to put up a good antenna, or indeed for those who live in a flat

where a garden is not available.

For people without the ability to erect antennas, a remote station

can literally transform their enjoyment of amateur radio. It can be in-

stalled far away in the countryside, or at a friend’s property where ample

antenna space is available.

Basic Overview

This chapter is based around experiences with the RRC-1258 MkII from

Microbit. It comes in two parts; one for the remote end and one for the

home end. The remote unit controls Voice Over IP and serial data to the

rig and is connected to a router via a Local Area Network hub, which in

turn is connected to the Internet and a Web Switch for switching relays

(which will switch the power supply on and off as well as the remote

controller and the rig). The home end comprises a PC with Windows XP

running Ham Radio Deluxe, a Virtual Comm Port Emulator (for the

Microham unit) and the RRC-1258 MkII controller, which is connected

directly to the router at home via an Ethernet cable. Headphones,

iambic key, foot switch and microphone all connect to the control box.

When complete, the Internet will carry signals between home and

the remote station, and here lies the essence of using a remote station

which could be located anywhere in the world.
