The TinySA and NanoVNA are both compact, affordable test instruments used in radio frequency (RF) and electronics work, but they serve different primary purposes: 🔍 TinySA (Tiny Spectrum Analyzer) Purpose:A…
Evidence for dark matter comes from multiple, independent lines of observation across astrophysics and cosmology. Here are the main ones: 1. Galaxy Rotation Curves 2. Gravitational Lensing 3. Cosmic Microwave…
Reducing noise in a 1420 MHz radio telescope setup (i.e., for detecting the hydrogen line) involves addressing both internal and external sources of interference. Here are the most effective steps…
If I use a filter at 1420 MHz that causes 3 dB loss and in amplifier beforehand that gives 3dB gain, will that cancel it out? Not exactly — a…
A long Yagi antenna tuned for 1430 MHz can still work at 1420 MHz, but with reduced efficiency and some detuning effects. Here’s a breakdown of what you can expect:…
TV satellite frequencies in the USA vary depending on the satellite, provider, and whether the service is free-to-air (FTA) or encrypted. Here’s a general overview: 🛰️ Main Satellite Bands Used…
The amount of sky covered by a radio telescope is typically referred to as its field of view (FoV). Key Terms: FoV≈λD radians\text{FoV} \approx \frac{\lambda}{D} \text{ radians} where λ\lambda is…
