"That would make sense," replied Duncan, breaking a moment of awkward silence.
Duncan displayed some information on one of the large screens mounted on the wall of the conference room:
MT63 is a digital radio modulation mode for transmission in high-noise situations developed by Pawel Jalocha SP9VRC. MT63 is designed for keyboard-to-keyboard conversation modes, on HF amateur radio bands.
MT63 distributes the encoding of each character over a long time period, and over several tones. This code and symbol spreading implementation is key to its robustness under less than ideal conditions. The MT63 mode is very tolerant of mistuning, as most software will handle 120 Hz tuning offsets under normal conditions.
Mode | Symbol Rate | Typing Speed | Duty Cycle | Modulation | Bandwidth | ITU Designation |
---|---|---|---|---|---|---|
MT63-500 | 5 baud | 5.0 cps (50 wpm) | 80% | 64 x 2-PSK | 500 Hz | 500HJ2DEN |
MT63-1000 | 10 baud | 10.0 cps (100 wpm) | 80% | 64 x 2-PSK | 1000 Hz | 1K00J2DEN |
MT63-2000 | 20 baud | 20.0 cps (200 wpm) | 80% | 64 x 2-PSK | 2000 Hz | 2K00J2DEN |

"Perhaps this is overkill and irrelevant, but I've done a considerable amount of research regarding the beacon that ship appears to transmit," said Duncan. "First, I've discovered the encoding scheme of the beacon. Second, I've successfully decoded it. Third, from what I can tell, the content of the message doesn't seem to have any significant meaning but there are strong indicators that, assuming the sphere is indeed transmitting it, this thing is OLD."
Duncan cleared his throat. "I'm talking centuries old, folks. Much older than me."
"Because of the format?" asked Camay.
"No, Dr. Thameh," replied Duncan. "The format dates back to the year 1997 but, due to how this thing vanished and re-appeared, I have a strong hunch something far more bizarre is going on here related to this thing's origin."
"Care to elaborate on that hunch," asked Jax, incredulously.
Duncan adjusted his glasses. "Well, if you insist. It's just a wild theory of mine, anyway. Have you ever heard of radio signals going backward in time?"
The room erupted in raucous laughter.
Duncan sat back down. "Yeah, yeah... hey, never mind."
