Power supplies 3.3 V, 1.2 V; T
all others 10 %; FM/AM modulation = 54 %, 1 kHz modulation frequency; measured in application PCB (see
16 MHz crystal frequency, loaded with 75
settings (recommended) except internal mono audio and IF demodulation. The low IF spectrum is delivered by a professional
downconverter.
