Well spotted: 2400 kS/s divided by 16 is 150 kS/s. 16 is the default decimation with RTL-SDR. Check the "Dec" button #7: https://github.com/f4exb/sdrangel/blob/master/plugins/samplesource/rtlsdr/readme.md
Brgds, Edouard.

What is you device ?  
With 2.4 S/sec sampling rate your should have +/- 1.2Mhz from 
center frequency. May be you have to regulate downsampling control to 1.
