Description

Hi, I have an SDR dongle connected on a Raspberry Pi 3 running Kali Linux Arm64.

The SDR itself I bought from here:

https://web.archive.org/web/20190212141813/https://www.aliexpress.com/item/100KHz-1-7GHz-Full-Band-UV-HF-RTL-SDR-USB-Tuner-Receiver-R820T-8232U-Ham-Radio/32859880270.html

Trouble is, whenever I connect to the rtl_tcp server remotely, it exits:

tl_tcp -a 192.168.200.132
Found 1 device(s):
  0:  Realtek, RTL2838UHIDIR, SN: 00000001

Using device 0: Generic RTL2832U OEM
Found Rafael Micro R820T tuner
[R82XX] PLL not locked!
Tuned to 100000000 Hz.

Use the device argument 'rtl_tcp=192.168.200.132:1234' in OsmoSDR (gr-osmosdr) source
to receive samples in GRC and control rtl_tcp parameters (frequency, gain, ...).

Testing with the -t flag is fine:

rtl_test -t

No E4000 tuner found, aborting.

But testing with a sample rate results in the same undesired behavior.

Info: This tool will continuously read from the device, and report if
samples get lost. If you observe no further output, everything is fine.

How do I keep this from happening?
