I think it is ready enough. PULL request will follow in next days... The next step I am going to add SDR API is tuner gain controls. Modern silicon RF tuners used nowadays has many controllable gains on signal path. Usually there is at least 3 amplifiers: 1) LNA gain. That is first amplifier just after antenna input pins. 2) Mixer gain. Quite middle of the signal path, where RF signal is down-converted to IF/BB. 3) IF gain. That is last gain in order to adjust output signal level to optimal level of demodulator. Each gain controls could be often manual or automatic mode (AGC). Total gain is something like sum of all gains. My plan is to implement these 3 gains with manual/auto switch and group all those to one master/total gain.
