Success with detection! Bits and pieces arrived to make new aerial – and attached are test screenshots from Spectrum Lab – 6 stations seen clearly. This time, for some reason,…
Note this post doesn’t look any question about whether the paint affects signal reception. It only addresses whether the paint will work with a paint sprayer. **Hammerite** paint can be…
The name “Soapy” in SoapySDR (and the associated Soapy drivers) comes from the idea of making SDR hardware support clean and simple — as in “soap makes things clean.” SoapySDR…
This question is relevant to considering how close two observers need to be to each other in order to observe the same muon cascades, and hence obtain similar muon detections/have…
This is one of those things that sounds boring until it suddenly explains all your noise problems. Alright — let’s break it down in human terms. 🎙️ Unbalanced microphone input…
To restore a Veeam server-led Linux backup (Agent managed by Backup & Replication) as a bare-metal / full image restore, you must use Veeam Recovery Media — not just file-level…
The answer isn’t “magic DSP.” It’s architecture. And a bit of ruthless engineering discipline. Modern SDRs don’t actually have “less noise” in the physics sense — they have more stable,…
This is one of those things that feels mystical until you unpack it — then it’s just physics quietly doing its thing. Short answer:There isn’t really a “mutual ground level”…
Absolute workhorse of RF switching. WHAT IS A PIN DIODE? A PIN diode is a semiconductor diode with three layers: The middle layer is a thick, undoped (intrinsic) region. That…
WHAT IS A DICKE SWITCH? A Dicke switch is a rapid RF switch used in radio astronomy to reduce receiver gain drift. It switches quickly between: This technique was invented…
