i Guess he wouldn`t dare to build schematics like this very complicated, what he was trying to look for maybe a sort of a walkie talkie transceiver using a fixed frequency, why not try using Audiguru`s FM transmitter and add a few components for the receiver? perhaps it would be then easier using only few components
No, he isn't going to learn very much about mobile radio by building something that simple. The most basic project i would recommend would be to build a two-way voice transceiver with these kinds of features:
- transmit and receive on channels in the range of 144 to 148 Mhz (lots of schematics out there for amateur band)
- 25 KHz channel spacing (easy to find an IF filter)
- synthesized oscillator (no point in learning about radios without synthesizers)
- FM modulation (as this is most common in VHF and UHF two-way radio)
- 2 watts output from transmitter (modest but still challenging)
- dual conversion superheterodyne receiver with 45Mhz first IF and 455 KHz second IF (relatively easy to build using ICs and readily available
filters)
- 1 watt receiver audio speaker , with squelch function
There are schematics and plans out there for similar simplified FM two-way radios, but need a bit of work to find them.
Consider a kit if you can find one. Doing it from scratch is complicated.
Lots of manuals here too:
