Learning radio recieving/ transmitting lesson

This is me doing my own research into this in an attempt to eventually build a working version of my walkie talkie invention. And if I ever forget one of these facts, or need to cross check, or confirm, I can easily refer to this documented research page of mine.

Search wiki for: transceiver, reciever, transmitter, transponder, antenna, radio waves (good for converting Mhz and finding correct frequency to transmit/ receive), walkie talkie, wave length, resonance,
tesla coil(good for the theoretical bumpy wire version that may amplify the signal to the transducer housing, resonance between bumps, long bumpy wire is amplified signal strength along with resonance maybe). Tesla coil summarised is that the voltage increases exponentially at resonance and so it needs and air core and far apart winding to prevent arking between windings.
Amplitude modulation. summarized amplitude/amplify is strength of the signal being on and off, low amp is off and high amp is on. This is voice which is piggy backed on a carrier wave which is produced by the ceramic resonator.

Piezo Transducer on wiki and shopping. How to make a contact mic walk through. in order to experiment with the piezo transducer without soldering it, just use paper clips to clip onto both contact points of the disc.

Simple transmitter circuit on google images and the article attached to the picture. Summarized this is for if you want to amplify the signal with batteries and if you do not make it a transceiver. transformer unneeded in my design and I use a ceramic resonator instead of a crystal oscilator.
Thin(thin for utilizing skin effect, for more surface area on thin wire) and long wire is very good for receiving more of a radio signal

reactance electronics

electrical impedance Summarized impedance means the level of resistance to an AC current flow. Inductive reactance resists high frequency AC flow, while capacitive reactance resists low frequency AC flow.

ceramic resonators may or may not need a capacitor attached to them in a circuit based on wether they have one already built into the resonator or the frequency may not have spurios frequencies(seen under "crystal oscillator") at that original frequency.
