Re: ExtIO_RTLSDR# - custom ExtIO for RTLSDR

1.22 was the first and only version with ExtIO capability but don't hold me to that. You can install SDRuno 1.22, copy folder with exe files to another location and then update to the latest version. In such way you can start SDRuno 1.22 ExtIO (from copied folder) with no need to uninstall the late...

Re: Add on LevelMeter plugin

Also note, that level depends on selected bandwidth, so when you measure level in CW mode for 500 Hz bandwidth and in AM mode for 20 kHz bandwidth, these levels will be different. Also no...

You could also make the bias-t in it? nice idea, I will look how to do it. But this operation may be unsafe, since enable bias-t for magnetic loop antenna may leads to hardware malfunction. So, there is need additional check for enable it. I've realized that trying to use scale for calibration is n...
