It came all at once and its sound dinned his ears and re-echoed from the smooth walls of the Station. The sound snapped Paul from his place by the window-dome. It grated on his ears until he could rush downstairs to the radio room to turn the volume-gain control down so that the audio signal fell below the overload point. From a raucous, nerve-tingling screech, the volume fell until distortion no longer fouled up the filtered purity of the signal-note broadcast from far-off Terra four years ago. Paul measured the signal strength and found it entirely satisfactory. He coupled the recorders to the gear, and then settled back to await the arrival of the modulated timing signals that were transmitted after an interval of straight tone, the first period to be used for establishing contact before the actual timing of the transmission-time began. Once the radio signal was coming in perfectly, Paul turned his attention to the Z-wave receiver. He tuned it gingerly, cautiously. And then it came to life! Paul cried in exultation. His was success! True, it was a weakling signal that faded and died at times, but it came in strong and clear enough for recording in the periods of good reception. A bit of work and research, and the construction of a real interstellar Z-wave station would remove this fading. Paul snapped the extra recorder on, and then began to dream his dream again, this time more strong than ever before. He had connected the Z-wave equipment at Terra's Z-wave central to the big interstellar radio transmitter, lacking a Z-wave transmitter for his own use. So that now he was hearing the Terran end of conversation. It was a woman's voice that talked from Terra to someone currently on one of the planetary outposts of Sol. "... but it won't be long, my dear.... Of course, it seems so.... Do that, by all means.... In a month, you say?... I'm very happy about that...." here the signal faded for a full minute. It returned again, "... Terry said so.... How do I know?... By all means, my dear...." and here again the signal faded. But it was enough. Exultation filled Paul. This was proof. This was the door, opening for life upon everything he ever hoped to gain, everything he hoped to be. It gave him what he wanted to offer life, and by happy circumstance, he had found the one he wanted to offer it to. He could go to Nora, not as a technician in the Bureau of Astrogation but with a grand future of success and opportunity to build ever upward and ever onward to real fame and fortune. Not the real success in his hand, for when the final success in life comes, ambition and desire begin to wane. But far more exhilarating was the hope of success, the chance to work for a magnificent future together. He gloated for hours, measuring the radio signal as few radio transmissions have ever been measured before.
