Modify sox command line in grape-utils.sh:grape_create_wav_file() to output a 32 bit floating point 10 Hz wav file for GRAPE. It appears sox by default was outputing signed 32 bit int wav files. soxi output before: Input File : '24_hour_10sps_iq.wav' Channels : 2 Sample Rate : 10 Precision : 32-bit Duration : 24:00:00.00 = 864000 samples ~ 6.48e+06 CDDA sectors File Size : 6.91M Bit Rate : 640 Sample Encoding: 32-bit Signed Integer PCM soxi output after: Input File : '24_hour_10sps_iq.wav' Channels : 2 Sample Rate : 10 Precision : 25-bit Duration : 24:00:00.00 = 864000 samples ~ 6.48e+06 CDDA sectors File Size : 6.88M Bit Rate : 637 Sample Encoding: 32-bit Floating Point PCM
Add args to sox to create floating point 10 Hz GRAPE wav files
decoding.sh:decoding_daemon() ADC overload logging appears to be broken with floating point wav files. Tried to hack in a fix, but I don't know bash well enough to know if this is solid. adc_overloads.log before: DATE_TIME OV_COUNT NEW_OVs RF_GAIN ADC_DBFS N0 CH_DBFS CH_GAIN ev/shm_wspr.wav: 696630 43 25.0 -17.9 -149.7 -70.0 0.0 ev/shm_wspr.wav: 696685 55 25.0 -18.2 -149.2 -73.3 0.0 adc_overloads.log after: DATE_TIME OV_COUNT NEW_OVs RF_GAIN ADC_DBFS N0 CH_DBFS CH_GAIN 250127_0157.wav: 696695 0 25.0 -18.4 -150.0 -82.9 0.0 250127_0158.wav: 696754 59 25.0 -18.4 -149.7 -85.3 0.0 It's possible this is not a bug and just something wrong with my hacked up config, so please check a known working site for confirmation.
