Page 5 PK-232 OPERATING MANUAL PREFACE INTRODUCTION Welcome to the exciting world of digital Amateur Radio! You've joined the ranks of the fastest growing modes in Amateur Radio since the FM repeater. Your AEA PK-232 Data Controller is the connection between your computer and radios. The PK-232 performs all the 'magic' of establishing data and text communications between your station and many other communication facilities equipped for digital communications.
Page 6 PK-232 OPERATING MANUAL PREFACE BATTERY BACK-UP NOTE: Your PK-232 uses to batteries to back up the user-programmable values in the system. If you don't install batteries, you'll have to re-enter all of your personal system settings each time you turn on the PK-232. Your PK-232 will operate normally in all modes but will not re- tain your personalized parameters such as your call sign, until you install three AA-size bat- teries in the battery holder inside the chassis cover.

PK-232 OPERATING MANUAL OPERATING MODES Except for the short delay in starting before sending your traffic, you can operate FEC using the same typing and receiving techniques as in CW or conventional Baudot and ASCII RTTY. The FEC mode does not use interaction or 'handshaking' between your sta- tion and the distant station.
Page 80: Amtor Switching-Time Considerations
PK-232 OPERATING MANUAL OPERATING MODES 4.5.8 AMTOR Switching-Time Considerations For operation in AMTOR Mode A (ARQ), your transceiver or transmitter-receiver combina- tion must be able to change between transmit and receive within 20 milliseconds. Most semiconductor-based radios can easily meet this specification. Many older tube-type ra- dios that use electromechanical relays operate very well in AMTOR Mode A (ARQ).

PK-232 OPERATING MANUAL INTERNATIONAL HF AMTOR CALLING FREQUENCIES APPENDIX C – INTERNATIONAL HF AMTOR CALLING FREQUENCIES Since the earliest days of AMTOR (around 1977), AMTOR operators around the world have agreed on the use of certain informal, internationally recognized calling channels. This is similar to the conventional operating methods of the commercial stations using SITOR the ancestor of AMTOR.
Page 206: Appendix D Amtor Operating Suggestions From G3Plx
PK-232 OPERATING MANUAL AMTOR OPERATING SUGGESTIONS FROM G3PLX APPENDIX D - AMTOR OPERATING SUGGESTIONS FROM G3PLX Introduction The following text is reproduced verbatim from a letter from Peter Martinez, G3PLX, dated 9/24/84, on the subject of good AMTOR operating practices. This paper is reproduced here by ex- press permission of the author and is offered as a guide to AMTOR operation from the one man most responsible for bringing AMTOR into the amateur radio fraternity.
Page 207 PK-232 OPERATING MANUAL AMTOR OPERATING SUGGESTIONS FROM G3PLX 2.5. Finally, make an ARQ call to the distant station and attempt an ARQ contact with your sta- tion as master rather than, as in 2.4, as a slave. If no contact results, yet the distant station indicates that he was replying to the call, then the problem is that the radio is too slow to change from transmit to receive.
Page 208 PK-232 OPERATING MANUAL AMTOR OPERATING SUGGESTIONS FROM G3PLX 3.2.2. If tail-ending on a previous contact, and the intention is to call one station on ARQ and his SELCAL code is not known, then there are two ways to proceed. 3.2.2.1. There is a convention in operation amongst AMTOR operators in respect of the way to choose the station SELCAL code from the station call sign.
Page 209 PK-232 OPERATING MANUAL AMTOR OPERATING SUGGESTIONS FROM G3PLX station will have 'netted' onto that. It often happens that an offset at either station will then result in the signal from the slave received at the master being a bit off tune. If the master station then readjusts his transceiver main tuning dial to remedy this error, he will also offset his transmitter, probably putting his signal off tune in the distant slave's receiv- er.
Page 210 PK-232 OPERATING MANUAL AMTOR OPERATING SUGGESTIONS FROM G3PLX 3.4.3. Fixed-channel working Since it is possible to leave an AMTOR station in 'standby' mode on a channel, and for any other station to make a specific call to that station, a common practice in AMTOR is to monitor such a specific frequency.
Page 211 PK-232 OPERATING MANUAL AMTOR OPERATING SUGGESTIONS FROM G3PLX exists to abort the later transmission of any unsent text which would be inappropriate to the new context of the break-in. 3.4.5. The AMTOR alphabet, like the RTTY alphabet, consists of two sets of 30 characters, with a switch made between them by two 'shift' or 'case' codes.
Page 212: Appendix E Amtor Theory
PK-232 OPERATING MANUAL AMTOR THEORY APPENDIX E – AMTOR THEORY 1.1. Definition and Standards References AMTOR (Amateur Teleprinting Over Radio) is a microprocessor-controlled, error-correcting data communications system. AMTOR is derived directly from the commercial practice known as SITOR (Simplex Telex Over Radio), as described in Recommendations 476-2 and 476-3 of the CCIR (International Consultative Committee on Radio, an agency of the International Telecommunications Un- ion, and in turn, of the United Nations.
Page 213 PK-232 OPERATING MANUAL AMTOR THEORY A third control code is used to command the direction of sending to be reversed, allowing the receiving station to reply. If there is no data waiting to be sent, Station A fills the three- character blocks with Idle characters.
Page 214 PK-232 OPERATING MANUAL AMTOR THEORY If both appearances of the same character are mutilated and fail the polarity-ratio test, no data are printed or displayed. Because the second appearance of the character occurs 280 milliseconds after the first appearance, the mathematical probabilities are that noise bursts will not destroy both appearances of the character.

So, while parity could detect errors and pro- voke repeats, the sequential nature of the code made its efficiency rate less than desirable. EBCDIC Extended Binary-Coded Decimal Interchange Code was developed in 1962. It uses 8 bits which makes it capable of transmitting 256 characters.

Page 227: Appendix M Facsimile Operation
PK-232 OPERATING MANUAL FACSIMILE OPERATION FACSIMILE OPERATION Overview Weather Facsimile (WEFAX) is transmitted throughout the Short-Wave radio spectrum, primarily to provide information to ships at sea. Typical stations you may find broadcast weather maps showing current as well as predicted weather conditions and satellite photographs showing the cloud cover over a large area.
Page 228 PK-232 OPERATING MANUAL FACSIMILE OPERATION Finding Fax Frequencies The following is a list of frequencies that seem to broadcast on a regular schedule. A few of these stations transmit 24-hours/day. We suggest you try the weather FAX frequencies listed below while you are becoming familiar with the commands.
Page 229 PK-232 OPERATING MANUAL FACSIMILE OPERATION After the cover of the PK-232 is removed, reconnect the power connector and the RS-232 cable to cmd: your computer and turn the PK-232 on. When you see the prompt, type to enter the AFSK-tone calibration mode. The screen should now be continuously displaying the VHF Mark-tone (approximately 1200 Hz) followed by R167 which indicates the variable resistor that adjusts the tone frequency.

Page 267 PK-232 OPERATING MANUAL Firmware Revision 30-DEC-88 Looking at just the setting row in the chart, the binary number 00010101 becomes evident. The binary number 00010101 equals the decimal number 21, and the hexadecimal equivalent is $0015 CUSTOM hence the reason the default setting for is $0015.

Page 279 PK-232 OPERATING MANUAL turned it off. See Question 2 in "SPECIAL NOTES FOR COM PAKRATT WITH FAX USERS." QUESTION: How do I find the DATECODE and CHECKSUM Of my PK-232 firmware? ANSWER: You must always be in the terminal mode to find this. First, whatever program you are using, escape to the terminal mode so you are displaying a command prompt cmd: ).
Page 280 PK-232 OPERATING MANUAL Even though the computer is turned off, the PK-232 will still perform as a digipeater. This is especially nice because you do not have to leave the entire system on to function as a packet station. * NOTE * Unattended operation is presently restricted below 50 MHz. While it is al- lowed above 50 MHz, third party traffic is not allowed on any frequency without the station operator present to control the system.
Page 281 PK-232 OPERATING MANUAL wires. If it does not key your radio, your cable is bad, or your radio is bad. Check MIC operation.
