Getting Started with the PK-88

Congratulations and thank you for your purchase of the AEA PK-88 Packet Data

Controller. The following is intended to help get you started and "on the air" with

the PK-88 quickly and easily.

The PK-88 operating Manual is filled with complete information on all commands and

operating modes. This doesn't mean you have to read it cover to cover before using

your PK-88. Most of the information you will need to connect your computer or terminal

and radio to the PK-88 can be found in Chapter 2 of the PK-88 Operating Manual.

If you are using one of our programs such as PC-Pakratt or PK-FAX for the IBM-PC and

compatibles, COM-PAKRATT for the Commodore 64 and 128 or MacRATT for the Macintosh,

then you should start with the Installation section of the Program manual. After you

have the program installed and running on your computer, then Chapter 2 of the PK-88

Operating Manual will describe how to connect the PK-88 to your computer and

transceiver.

AEA's programs such as PC-Pakratt simplify the way you enter commands to the PK-88.

This means that some of the sections of the PK-88 Manual that tell you to enter a

command in a certain manner will not apply. When using one of our programs on your

computer, sections 2.5, 2.6 and 2.7 of the manual can be skipped.

In general, if you are using one of AEA's programs such as PC-Pakratt, PK-FAX,

COM-PAKRATT, or MacRATT, the manual that comes with the program should answer most

questions. The PK-88 Operating Manual should only be needed as a reference when

specific Hardware or Command information is sought.

On the other hand, if you are using a Dedicated Terminal or Terminal Program on your

computer, you should carefully follow the set-up procedure outlined in all of Chapter

2 of the PK-88 Operating Manual. Sections 2.11 and 2.12 of the Manual describe how to

connect the PK-88 to several different kinds of computers which may be especially

helpful.

You will not need any of this information to get your PK-88 up and running, but you

may want to skim through the Addendum for the latest information on the PK-88

operating firmware.

NOTE TO PC-Pakratt USERS:

In order to run the PK-88 with PC-Pakratt, your PC-Pakratt

disk must contain a file PCPAKRA87.CFG. Contact AEA at

206-775-7373 if you have any questions.

This PK-88 has been certified under Subpart J of Part 15 of the FCC rules.

This equipment generates and uses radio frequency energy. If it is not

installed and used properly, that is, in strict accordance with AEA's

instructions, it may cause interference to radio and TV reception. It has

been type tested and has been found to comply with the limits of a Class B

computing device in accordance with the specifications in Subpart J of Part

15 of the FCC rules, which are designed to provide reasonable protection

against such interference in a residential installation. However, there is no

guarantee that interference will not occur in a particular installation. If

this equipment does cause interference to radio or TV reception, which can be

determined by turning the PK-88 on and off, the user is encouraged to try and

correct the interference using one or more of the following measures:

Reorient the antenna of the device receiving interference.

Relocate the computer with respect to this device.

your warranty card. Because of the numerous situations in which our product is used by

an unauthorized third party, we MUST verify that you are the licensed user. We may

choose to call you at the phone number listed in our records to verify your identity.

THANK YOU for your patience.

Product Update Policy

From time to time we will make available updates to the design of our products. These

sometimes are made available to the user who has previously purchased its products. We

can only tell you about these updates if we have your warranty card. PLEASE SEND IT IN

PK-88 OPERATING MANUAL PREFACE

INTRODUCTION

Welcome to the exciting world of digital Amateur Radio! You've joined the ranks of the

fastest growing mode in Amateur Radio since the FM repeater.

Your AEA PK-88 Packet Controller is the connection between your computer and radio.

The PK-88 performs all the 'magic' of establishing data and text communications

between your station, as well as many other communication facilities equipped for

digital communications.

With packet radio you'll have a 'private channel' while sharing a frequency with other

packet stations; you'll be able to 'read the mail' from other packet stations, log on

to computer-based 'bulletin board' or 'mailbox' systems, handle message traffic - in

short, you're now equipped to enjoy the advantages of digital communications and

error-correcting radio techniques in your ham shack.

Your new AEA PK-88 is the heart of your digital radio station. The PK-88's system

software is derived from the original TAPR TNC; it presents many of the advanced

features of that design, coupled with significant enhancements based on the experience

gained by thousands of TAPR-equipped amateur packet stations worldwide.

This manual is your guide into the realm of Amateur Packet Radio.

Join a packet radio club - they exist in all states as of this writing. You might also

subscribe to the ARRL publication 'Gateway,' which describes all the 'goings on' in

packet radio, and to the TAPR 'Packet Status Register,' which describes the

technically interesting happenings in the movement. There are many voice nets on VHF

and HF; they usually meet weekly. They are usually dedicated to making the newcomer

feel at home.
