The Last TechShack by Jason Kilhoffer

Coaxial Drift Book 1

Jason Forrester has spent a lifetime surrounded by the hum of electronics, the smell of solder, and the satisfaction of fixing what others threw away. But now his beloved TechShack—the last of its kind—is on the verge of closing for good, buried under corporate shutdown notices and an era that has moved on without him. As he inventories dusty relics and wraps up what he assumes will be his final days behind the counter, the shop's old HAM radio setup crackles to life with something impossible: signals encoded in Morse code, 80s TV themes, and the unmistakable screech of dial-up modems.

Determined to decode what he's hearing, Jason teams up with Jennifer, a sharp-tongued conspiracy podcast host, and Chad, a sarcastic teenage tech prodigy with zero patience for nostalgia but an undeniable gift for gadgetry. Together, the unlikely trio traces the signal back to Jason's own garage—his late father's domain—where they discover evidence that something alien or extradimensional has been trying to make contact for years, using old technology as its only bridge to our world.

Their investigation doesn't go unnoticed. Mysterious government agents begin tailing them, and strangers start turning up at the shop, quietly buying up vintage components they have no business wanting. Every answer they find opens a darker question, and every clue points deeper into a mystery that Jason's father may have spent his life trying to solve.

Using a prototype recovered from his father's workshop and a collection of analog relics, Jason and his crew construct a makeshift machine that tears open a rift between worlds. On the other side lies a surreal digital afterlife built entirely from obsolete technology—a forgotten dimension of dead circuits and abandoned frequencies. And it is dying. Only someone fluent in the language of analog tech and lost codes can save it—someone exactly like Jason.
