USER'S GUIDE 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 180 USER'S GUIDE 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 181 USER'S GUIDE 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 182 USER'S GUIDE AMTOR OPERATING SUGGESTIONS FROM G3PLX 3.4. Operating techniques on ARQ 3.4.1. Transmitter and receiver tuning An ARQ contact always starts with the master station making the initial call, and the slave replying. Thus the frequency will have been chosen by the master station, and the slave station will have 'netted' onto that.
- Page 183 USER'S GUIDE AMTOR OPERATING SUGGESTIONS FROM G3PLX er QSO, or both. It can only be the master station that leads in a 'hot' QSY. If the slave station were to attempt to lead a QSY, then, in the event that it was not successfully completed before the contact timed-out into a re-phase operation, the slave would no longer be transmitting, and there would be no way for the slave to establish a new fre- quency without restarting as a master and thus lose some traffic.
- Page 184 USER'S GUIDE AMTOR OPERATING SUGGESTIONS FROM G3PLX where it is essential to do so. The reason is that there are inherent reasons why recovery from such an interruption can result in garbled copy at one end of the contact, in particu- lar in 'figs' garble.

USER'S GUIDE 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 Union, and in turn, of the United Nations. - Page 186 USER'S GUIDE 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. Station A can send special blocks to indicate the following: The SELCAL of the station being called.
- Page 187 USER'S GUIDE 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.

EBCDIC Extended Binary-Coded Decimal Interchange Code was developed in 1962. It uses 8 bits which makes it capable of transmitting 256 characters. But for communications EBCDIC might be deemed a backward step because it has no parity capability.
