70 cm stuff isn't easy to build, but it's not impossible, either.  This is a
popular amateur radio band, so you can find a lot of construction
information looking at amateur publications.  There are plenty of DDS parts
capable of generating stable 435 MHz and many include fsk capability on
chip.  Amplifier parts are quite widely available, as well as mixers.  The
challenge is that capacitances and inductances at this frequency are quite
small, so construction techniques are a bigger deal than the actual
circuits.
