Bai Yang was stunned for a moment.
"Is that even possible?"
"Technically, there's no problem," Wang Ning thought for a while and scratched his not-so-hairy smart head, "but in practice, there should be quite a few difficulties, both in hardware and software."
"But it's worth a try," Bai Zhen sat opposite him.
The two pondered for a long while, exchanged glances, and then started a conversation in which no one else could understand a word.
"How do we transmit?" Wang Ning asked, "SSTV for images, FSTV for video?"
"FSTV won't work, using FM to modulate the signal takes up too much bandwidth, can't handle it on a 14MHZ frequency," Bai Zhen replied. "Our method needs to be as simple as possible."
"Then RTTY," Wang Ning said.
"Telegraphy?" Bai Zhen asked.
"Yeah, telegraphy," Wang Ning nodded.
"How to modulate the signal?" Bai Zhen asked again.
"FSK?" Wang Ning thought.
"AFSK," Bai Zhen shook his head.
"Then she'll need a sound card."
"Where do we find a sound card?"
