Internet Remote Operation

disadvantages but they could be enough to put you off such a project.

I have been very lucky at the remote end, as I have free Internet

access, free mains and good security for the equipment, hence this

project has been worthwhile.

Hardware Requirements

The project revolves around the remote control units RRC-1258 MKII,

as seen in Fig 9.1, produced by Microbit of Sweden.

On the left hand side you can see the controller which connects

to the radio at the remote end, while the controller on the right con-

nects to the PC and router at the home end. They look almost identi-

cal, except for a CW speed control on the right hand unit.

The small USB format sockets on the far left are used to program

the initial IP address of the units via a utility program which can be

downloaded from the SM20 website www.remoterig.com Alterna-

tively, a serial connection can be used on Com 1 for the same pur-

pose. The next socket, AUX/MIC, is where the microphone and PTT

are connected via a network type plug. Here I just made patch leads

to plug into my head set and PTT footswitch. My speaker plugs

directly onto the socket marked ‘SP’. At the remote end, microphone

and PTT leads are

connected from this

socket to the trans-

ceiver. A lead (grey) is

connected from the

speaker socket of the

transceiver to the back

of the controller, into the

microphone input

socket, as seen in Fig

9.2, as well as a serial

cable which controls the

rig, the 12V DC cable

and the network cable.
