Re: Audio volume level passed to apps lower than expected
Um, why the obsession with this?toggle quoted messageShow quoted text
Most front ends have a gain control on them. Some, such as rtlsdr dongles, have local AGCs. Hopefully those are left off where practical to give you some means of calibrating the system. AirSpy HF+ models are an exception. And they don't calibrate well as a result.
Within an rtlsdr dongle there are three gain controls. Each of them affect the antenna to consumer level for SSB and AM related modes. As it happens ALL analog gain controls in the system also have an influence on both system noise figure and dynamic range as a tradeoff. Once past the A/D converter all gain controls are equivalent and do the same thing for SSB and AM paths. Adjust them to comfortable settings and move on.
