🔍 Key Concepts

• Regeneration in a receiver and how it affects gain and selectivity • How to deal with interference or nearby unwanted signals in a simple regenerative receiver • The trade‑off between sensitivity (gain) and selectivity (narrow tuning)

💭 Think About

• When trying to pull a weak CW/radiotelegraph signal out of interference, do you usually want the receiver to have a narrow or wide bandwidth? • How does increasing regeneration, just below oscillation, change both the gain and the sharpness of tuning of the receiver? • If you couple the antenna more strongly to the tuned circuit, what happens to the selectivity of that tuned circuit?

✅ Before You Answer

• Identify which option would tend to narrow the bandwidth of the tuned circuit, helping to separate signals close in frequency • Consider which adjustment might actually broaden the tuning and let in more interference, even if it increases signal strength • Make sure the chosen option is consistent with operating a regenerative receiver just below the point of oscillation for CW reception in interference.
