70cm ham radio tranceiver covering ism band with >10watts eirp, sweeping with white noise. opens doors, gates etc.
high power takes care of the frontend, the noise spectrum does the rest.
i developed the receiver for the 'bosch blocktronic', via a subcontractor called c.e.l.
not knowing who i actually worked for and what the circuit was to be used for, i was told to keep it as simple as possible.
so i used a 0-v-1 frontend and a sawtooth filter for the 'better' models. the 'rotating code' is anything but random.
