Brief description: 'Boost SNR' fails to function when FFT size slider control in IF Noise Reduction changed
SET UP: Freq 95.1MHz weak signal
SDR# rel 1710
HF+ DP Firmware: R3.0.6-BB
Win 7 64
Open fresh new SDR#1710 program:
Open Zoom FFT* menu
Enable IF, Enable MPX, Enable Audio - all ticked
Open IF Noise Reduction* menu.
Boost SNR: tick . This results in a) improved SNR (intelligibility of speech) & IF display in Zoom FFT shows 40dB FS IF gain lift.
However if I then move the FFT Size slider control in IF Noise Reduction menu the Boost SNR tick remains, but the improved SNR appears to be lost & the IF spectrum gain of 40dB is lost.
First time I've tinkered with the SNR Boost in custom settings. Is the above an expected result?
I have to close program & open again to restore functionality of Boost SNR feature.
