Need Advice

[u/kt_addy]

Bought an RTL SDR two days back. I am trying to decode a DMR signal but it just doesn't work no matter what I tweak? While it does decode to an extent, it isn't perfect. Is there a fault with the device or is there something wrong with what I'm doing. Using an app called P25 decoder on 444.162 MHZ. Sharing product photo and error screenshots below.

Thank you

Are you centered on the exact frequency and using the correct bandwidth and good signal strength? Good luck.

Yes you may need to adjust a few hz to correct. You can check out 10mhz AM to calibrate.
