By Richard A. Eckel ©Copyright 1994 All Rights Reserved. Ever since I started flying RC sailplanes about two years ago I knew that I would eventually move up to a computer radio. I’m an engineer with a strong interest in computers and technology. Obviously the high tech sailplanes and computer radios have a strong attraction for me.

I have always admired the JR radios and finally decided that I would purchase and learn how to program the JR388. Let me lay it on the table – the radio is not hard to program but I found the manual very difficult to decipher. Perhaps I find the manual difficult because I am a 'top down' learner.

That is, I want to understand the overview before I learn which buttons to push. If you are the same way or are just interested in a different view of programming the JR388 I think that this article will be of interest to you.

Intent of Article The intent of this article is to supplement the manual in some respects and to present my understanding of the programming and organization of the JR388. Along the way I will point out some potential traps in the programming. After reviewing the organization of the radio and its functions I will recommended setup procedures and tell you about some programming tricks that might be of interest.

I am hardly an expert on programmable radios. I do not know how other radios such as the Vision or Super 7 handle their progarmming and I will not be doing any comparisons. I have simply spent a good deal of time analyzing the JR388 and want to pass along what I have learned. Receiver Channels The receiver channel assignments are very important to the programming of the JR388. JR has preprogrammed a variety of useful mixes in the transmitter but they are dedicated to specific channels. If you want the radio to program easily and with maximum flexibility it is best connect your servos to the channels specified in the manual. To keep you interested, the receiver channels are referenced in the manual by a variety of names.

Table I lists the channels and the aliases I found in the manual. In this article I will refer to receiver channels by their sailplane assignment followed by the channel number – i.e. When I use the term Flap or Aileron without a channel designation it refers to the mixed channels together controlling both flying surfaces. Table I lists the receiver channel number followed by its receiver label alias followed by its sailplane setup alias followed by any other alias I came across. Keep Table I handy when you are reading the JR manual. TABLE I Receiver Channels Receiver Channel Aliases Channel Receiver Mark Sailplane Alias 3 1 Throttle Spoiler 2 Aileron L.
