Circuitous Signals: The Case of the Wavering Waves

Last night, while monitoring the usual shortwave frequencies, I encountered a peculiar occurrence—a rhythmic interference pattern on frequency 47 that persisted for over an hour. This wasn't just static; it was structured, almost like a heartbeat.

21:17 Hours: The pattern emerged, interrupting a clear signal I had logged for weeks. My modified SDR equipment highlighted the anomaly—a series of three short bursts followed by a long pause. This repeated, unwavering, for exactly 47 minutes.

I've been tracking this for 7 years now, and although the numbers don't lie, they don't always tell the whole truth either. Coincidence has a pattern if you look long enough.

Investigation: I logged the sequence and cross-referenced it with previous data—similar pulses had been noted but not as prolonged or precise. At first glance, it seemed like another military exercise, perhaps encrypted communications testing. Yet, this signal was too refined, too deliberate for random military chatter.

Anomalies or Equipment?

Was it a malfunction in my setup? Possible, but unlikely. I double-checked all connections and settings. Everything was in perfect condition. A local atmospheric effect? The skies were clear, visibility uncompromised.

The Mundane Explanation: Nearby power lines often disrupt signals. Could this have been a result of electrical line maintenance? A plausible contention, but maintenance teams generally don't operate at that hour.

Pattern Analysis: The repetition of 'three'—three bursts, three pauses—stood out. A number familiar in my logs, often appearing before significant anomalies. Close isn't proof. I know that. But close keeps happening.

Preliminary Conclusion: With no immediate rational explanation, the incident remains open in my notebooks. I can't claim any proofs, and yet, I can't dismiss the uncanny nature of these waves either. The sky doesn't lie, but it doesn't show you everything either.

It would be easy to brush this off as coincidence or equipment glitch, but every time I think I've seen it all, something new presents itself. Another night, another almost.

Stay vigilant.
