Been noticing something similar here in Durham, though I'm still fairly new to EVP work so take my observations with a grain of salt.
Running a basic setup - Zoom H1n recorder with a cheap omnidirectional mic in a Faraday-adjacent configuration - and the sessions from around the 10th–14th last month did seem qualitatively different. Less white noise baseline, but the anomalous responses felt more structured somehow. Cleaner formant patterns when I run the audio through Audacity's spectrogram view.
My working theory, and I stress it's just a hypothesis, is that elevated geomagnetic activity might be affecting the conductivity of whatever medium interdimensional signals propagate through. The Schumann resonance spikes during strong solar events are well documented, and if entities are using EM-adjacent frequencies to communicate, it stands to reason that a more energetically charged environment could improve signal fidelity.
What I'm less sure about is whether the content of responses has changed, or whether we're just getting better carrier signal. There's a distinction worth drawing there.
A few questions for those with more experience:
Are you logging your sessions against the K-index at time of recording? Feels like that correlation data would be worth accumulating., Has anyone used a RTL-SDR dongle alongside traditional audio capture during flare periods?
Would genuinely value hearing from people who've been doing this longer than me. Particularly interested if anyone's noticed whether specific types of entities seem more active during high solar activity, or whether it's indiscriminate across the board.
