Ves pushed his setup to its limits when he failed to get a response. Due to the inverse-square law, the poor little transceiver had to accommodate an increasingly alarming amount of power.
Neither the salvaged energy cells, the improvised power converter or the hastily upgraded transceiver handled the increasing load well. Ves frequently shut down the power to cool down the stressed devices and replace a few of the more delicate components that only hung on by a thread.
His persistence finally paid off when his shabby transceiver finally returned a response. It came in with dense encryption that made no sense if Ves didn't have the right key.
