Light through the walls of the tent turned the TOC into a vast russet mushroom, though the fabric looked dull brown by daylight. Daun could hear voices, some of them compressed by radio transmission.
It was conceivable that the problem was inside the TOC, either in the console or the connecting cables. Daun was tempted to check out those possibilities first, but he decided not to waste his time. The console was of Frisian manufacture and sealed against meddling by the locals.
The cables had been laid by the previous pair of FDF advisers. They’d done a first-class job; Daun had checked and approved every millimeter of the route the day he and Anya arrived. Unless somebody’d driven a piece of tracked construction equipment through the TOC, the conduits should be fine. The indigs were capable of doing something that bone-headed, but Daun would have heard it happening.
The thirty-meter mast was a triangular construct set in concrete and anchored to the trailer housing the battery commander. The unit telescoped in three sections. Daun could lower the mast to save most of the climb, but re-erecting it would require help to keep the guy wires from fouling. He didn’t trust the indigs to do that properly even during daylight.
He squelched to the base of the mast, hooked his safety belts, and began to climb the runglike braces which bound the three verticals together. The mast was formed from plastic extrusions, not metal, but the rungs still felt icy to Daun’s bare hands. They were also slick as glass.
The sensor wands’ removable recording cartridges provided extremely precise information on all movements within the coverage area. If a human passed within two or three meters of the wand, the retrieved cartridge could determine the state of health based on body temperature and pulse rate. Such data were remarkable but useful only as the raw material for a historical overview.
Base Bulwark collected coarse sensor readings in real-time, via coded frequency-hopping radio signals. As the messenger had implied, this was the second miserable night in a row that the ultra-high gain antenna atop the mast had failed.
Last night a matchhead-sized integrated circuit had blown: the sort of thing that happened only occasionally with Frisian hardware, but always at a bad time. Anya had unplugged the blown chip and replaced it with a good one.
Anya, simply glad to have the antenna working again, had pitched the bad chip out into mud and darkness. If she’d instead saved the fried unit, Daun would have examined it to determine the cause of failure. Long odds the problem was due to manufacturing error, but there was always a possibility that a short within the box was causing a hot spot.
The chance to diagnose the underlying problem instead of merely fixing the symptom was much of the reason Daun had volunteered to climb the mast. Besides, he liked the hardware part of his work well enough that he preferred to be doing it instead of playing cards with strangers he couldn’t respect and didn’t much like.
There were guy wires on each of the three sections of the telescoping mast. When he reached each set of guys, Daun unhooked one of his two safety loops, rehooked it above the wires, and repeated the process with the second loop. At no time did he trust merely his boots and grip to keep him on the mast. Daun wasn’t so much cautious as perfectly methodical. The notion of cutting corners to lessen his exposure to the chill drizzle didn’t cross his mind.
Viewed from the top of the thirty-meter mast, the lights of Bulwark Base had a surreal innocence, like the gleam of will-o’-thewisps in a nighted meadow. Rain softened the patterns and dusted glare into sparkle. The scene wasn’t beautiful but it had a dignified tranquility, far removed from the muddy truth. The glowing canvas of the TOC could be the entrance to the Venusberg, and Daun could imagine that flashlights in the tents on the perimeter were cupids twinkling around the goddess of love.
The receiving antenna at the mast peak was enclosed in a weatherproof capsule about the size of a soccer ball. The covering was dull gray plastic which was reasonably sturdy but remained transparent over most of the electromagnetic spectrum. Wherever possible, the sensor wands transmitted over microwave frequencies, but those without a line of sight to the receiver used VHF or UHF as circumstances required.
Daun arranged the working canopy over the capsule. When he had it stiffened into position, the monomolecular sheeting blocked the rain completely. Before then, however, he managed to pour what felt like a liter of cold water down the back of his neck from the canopy’s folds.
