Gqrx with Spyserver support only shows blue line...

[PA8E]

Hi all,

Since a few days I'm using the experimental version of Gqrx with Spyserver support. My remote RX-station has very limited bandwidth on ADSL so I need something more efficient then RAW rtl_tcp to transport HF-signals from my RTL-SDRv3 and RaspberryPi. Turns out only SDR# seems to work but that is not my favourite SDR program (to say the least). Gqrx is.

But I can't seem to get it working. I've tried every sample rate Spyserver offers, played with bandwidth etc. Only thing Gqrx showing is a blue line in the middle and playing a repeating tone.

Anyone any idea what I'm doing wrong here?

Did you ever resolve this? I get the exact same thing.

Same, I have no other error logs to offer, but if anyone can tell me where to pull logs, I'll gladly post them.

Hi,

how did you set up the connection? Did you make a trick with the sample rate as described here https://groups.google.com/g/gqrx/c/aVaD2uGi0Ng/m/QE0T-oixAQAJ

Cite "Be sure to select sample_rate = airspy_rate/N, where N = 1, 2, 4, 8,
16, ... and not greater than the max allowed I/Q rate in the spyserver
config. "

Best,
Semen
