Up/Down buttons on the radio or microphone allow tuning different frequencies or memory channels. Shift allows changing the transmit and receive frequencies for working through repeaters. The Noise ...

Design Exercise
... 2. The radio can require as much as 20 milliamps to play loudly. How big can the resistor be and still have the radio still work when the car battery is low? 3. How much power is dissipated in the zener when the car battery is high and the radio is off (the worst case)? Note: power equals voltage ti ...

Antique radio
An antique radio is a radio receiving set that is collectible because of its age and rarity. Although collectors may differ on the cutoff dates, most would use 50 years old, or the pre-World War II Era, for vacuum tube sets and the first five years of transistor sets.
