General exam question G2E09
Subelement G2, OPERATING PROCEDURES· Group G2E
How do you join a contact between two stations using the PACTOR protocol?
- A.Send broadcast packets containing your call sign while in MONITOR mode
- B.Transmit a steady carrier until the PACTOR protocol times out and disconnects
- C.Joining an existing contact is not possible, PACTOR connections are limited to two stations (correct answer)
- D.Send a NAK code
WhyPACTOR connections are limited to two stations, so a third station cannot join an existing contact. PACTOR is strictly a point-to-point protocol between exactly two stations, so a third station can't join an existing link the way you might join a net or a repeater conversation, answer C. There's no broadcast-monitor join method, no carrier-timeout join trick, and no NAK-code method for inserting yourself into someone else's PACTOR session.
