Help copy pasted:

rtlsdr_wsprd, a simple WSPR daemon for RTL receivers

Use:    rtlsdr_wsprd -f frequency -c callsign -l locator [options]

        -f dial frequency [(,k,M) Hz], check for freq.

        -c your callsign (12 chars max)

        -l your locator grid (6 chars max)

Receiver extra options:

        -g gain [0-49] (default: 29)

        -a auto gain (default: off)

        -o frequency offset (default: 0)

        -p crystal correction factor (ppm) (default: 0)

        -u upconverter (default: 0, example: 125M)

        -d direct dampling [0,1,2] (default: 0, 1 for I input, 2 for Q input)

Decoder extra options:

        -H do not use (or update) the hash table

        -Q quick mode, doesn't dig deep for weak signals

        -S single pass mode, no subtraction (same as original wsprd)
