🔍 Key Concepts

• Magnetron operation in marine radar systems • Purpose of TR (transmit-receive) and ATR (anti-transmit-receive) tubes • What a keep-alive voltage does in a vacuum tube or gas-discharge device

💭 Think About

• Which component actually generates the high-power RF pulses and might need a small, steady voltage to be ready to fire reliably? • Do TR or ATR tubes conduct only during transmit/receive switching, or do they need to be partially ionized all the time? • Is a crystal detector an active device that needs bias/keep‑alive voltage, or a passive one that rectifies RF signals?

✅ Before You Answer

• Identify which device is responsible for producing radar pulses, not just switching them. • Recall which tubes (TR/ATR vs magnetron) rely on a small, continuous bias (keep-alive) to maintain stable operation. • Confirm whether a crystal detector normally requires an external DC supply in basic radar receivers.
