If i remember correctly it uses the graphite in a pencil as a crystal similar to that of other crystal radios.
Yes because only television signals from some stations have gone digital. Crystal radios will pick up stations broadcasting on the A.M. broadcast band (540k to 1600K). These signals are amplitude modulated and crystal radios pick these up really well. You could also use them for Shortwave and pick up some stations. Am, FM and shortwave are still not digital.

a crystal can get large depending on how much it grows
Retail stores which carry the Motorola FRS radios include Best Buy, Future Shop and Visions Electronics. Big box retailers such as Walmart and Target also carry these radios.
One type of oscillator that can produce a 1MHz frequency is a crystal oscillator. Crystal oscillators use a quartz crystal to generate stable and precise frequencies. They are commonly used in electronic devices like radios, computers, and microcontrollers to provide accurate timing signals.
i could i know u arent such a big ........
big NO !

The radio's appearance has definitely changed over time. The newest radios are very small compared to the big and bulky radios of the past.
A batteryless radio can work with a power cord, or it can work by a solar cell, it mostly though operates by a handcrank. In MIT they are trying to figure out how to power a radio with FM radio signals. Works everywhere with radio signals which is everywhere!
