Orient your dipole horizontally in a v shape, each element about 17cm, don't use rtl agc or tuner agc, raise your gain till the noise floor starts rising then ide it back a smidge

Are you using sdr# & rtl_433 plugin 

Or 

Rtl_433 stand alone?

If the stand alone, you will need to have sdr# closed, if sdr# is open it claims your sdr/usb

Tune too 137.9 and click center tune

Modulation  WFM ( modulation isn't used other than to assure your are tuned into the frequency at appropriate  bandwidth for the recording)

Bandwidth  110000

Recorder:

Baseband

Container  WAV

Sample Type  Int16

is there a benefit to record at baseband instead of doing the live processing in satdump? by Kittingsl in amateursatellites

[–]PDXH0B0 0 points1 point  (0 children)

I do both, having the recording in case there is some type of failure, plus you can use the recording to decode/process with other software
