I'm working on project for school, and rather than simply buying a transceiver I want to build one. I'm studying Mechanical Engineering, so i virtually know scraps of signal transmission. All the schematics I have found want to convert an audio signal, from a mic, into a radio frequency. I just want to send a radio signal as a ping to another transceiver.
I'm hoping by removing the need for frequency conversion, the device will be smaller and require less power.
Less filtering and less amplification modules.
The idea is, if this represents a the block diagram of a transceiver, and I can remove the conversion requirements I can do away with the variable frequency oscillator, beat frequency oscillator, and mixers.
