How to restore a Veeam server-led Linux backup (Agent managed by Backup & Replication) as a bare-metal / full image restore

Admin February 16, 2026 No Comments

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…

Radio observation in hydrogen line (1420MHz)

How does a modern software defined radio attain an less erratic noise floor than older amateur radio sets?

Admin February 15, 2026 No Comments

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,…

How does a mutual ground level form between receiver and transmitter at distance from each other? And how does this apply to radio astronomy?

Admin February 15, 2026 No Comments

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”…

What are professional radio astronomy dishes made of?

Admin February 15, 2026 No Comments

Professional radio astronomy dishes are engineered for electrical reflectivity, structural rigidity, thermal stability, and low weight. The exact construction depends on frequency range (long-wavelength vs millimetre work), but most large…
