Note! Please be advised that operation from 90 kHz offset and up (such as 50.190) might produce distorted audio. Due to the Sphere sampling frequency of 192 kHz the following frequency offsets should be avoided:

90-96 kHz (Some audio sampling artifacts)
96 kHz (Dead lock = Sample rate / 2, will not produce any audio)
96-100 kHz (Out of band operation, audio will be distorted by bit quantization noise)
0-1 kHz (Near Local Oscillator Deadlock. Out of band operation, audio will be distorted by bit quantization noise)

Tuning HamSphere outside the specs is not prohibited, but please observe the audio limitations.
