A gravitational wave affecting the radio spectrum you say? What? Is that possible? Put your seat belts on and anchor down as we lift your understanding deeper into radio signal propagation!

Did you know about fluctuations in the earth’s gravity and the constant changes in its magnetic field? More than likely, that answer is a resounding yes. But have you dove deeper and considered that the changes affect the gravitational waves and cause underlying issues with the transmission and reception of all modes of signals?

We begin this short brief with discussion on How Gravitational Waves Could Generate Radio Signals inspired from an article from MIT in 2009. In this article, the study and research divulges that [even though potentially weak signals] the amplitude and frequency of change in gravitational waves does and can emit transmission detectable on many communication radio types.

Have you ever been listening to a radio and the station goes quiet but there is some underlying, indiscriminate noise other than the normal buzz of static? Have you ever watched a television set that loses its signal and the same occurs underneath the white screen peppered with black and grey dots? It is like something is there but you cannot identify just exactly what.

You have just hear what has been perplexing signal enthusiast for decades [if not longer] and it may be leftovers from a period long passed. Are we indeed hearing the change of gravitational waves as a reaction to the changes in magnetic fields when impacted from the sun? The short answer, is yes.

The motion of Gravitational waves are transient displacements in a gravitational field—generated by the motion or acceleration of gravitating masses—that radiate outward from their source at the speed of light. With that, we can deduce that the suns solar conditions can affect the gravitational fields. Thus, the same can be said for the altering of those fields in the presence or absence of a an impactful K-index.

Leaving the rabbit trail behind, [trust me, you can get lost down there] it is proposed that you can listen for, hear, and identify the noise of space time events in action. The undertones generated from these events may not overtly impact your transmission and reception, but they could if you are say working a distant faint station during a contest or experiment to determine signal path and distance on the HF bands and your intended QSO cannot be heard above the noise.

So fathom the possibilities for a minute, read deeper into the plausibility, and gain better insight on what might need to be done to detect signal anomalies while constructing a station capable of getting through the noise!
