“Yes. Now if that was your uncle calling....”
“You’re still not sure it was Uncle Charlie?”
“Well, I guess I am. Let’s say it was. That’s another reason I figure he’s over toward the mountain range.”
“I’m not reading you too clearly right now,” Biff said.
Jack laughed. “I’ll try to explain. Charlie had a portable radio transmitter with him. A good one, battery operated. Its maximum range would be about 500 miles under ideal conditions. That means he’d have to have straight-line transmission.”
“You mean nothing in the way, like a high mountain?”
“That’s right, Biff. Transmission is greatly reduced if your wave has to bend over hills or mountains.”
“So you figure he’s got to be high enough to shoot a straight wave directly to Unhao.”
Jack nodded his head. “And the elevation around Jaraminka really fills that bill—5,000 to 6,000 feet.”
“How could he ever land in such rugged terrain?” Biff asked.
