RuntimeError: gr::io_signature(3)
Closed this issue · 5 comments
Hey, I didn't find any answers for this, so I thought I'd ask. I'm on openSUSE 42.1. gnuradio is version 3.7.8-3.11. I have a generic RTL2832U. gqrx works, so I know the RTL is accessible via gnuradio.
Running this:
./ham2mon.py -a "rtl" -n 4 -f 145E6 -r 2E6 -g 20 -s -40 -v 0 -t 30 -w
And I get this:
Traceback (most recent call last):
File "./ham2mon.py", line 136, in

File "/usr/lib64/python2.7/curses/wrapper.py", line 43, in wrapper

Any thoughts?
Sorry, just saw this issue. You need to remove the kernel module like so:
sudo rmmod dvb_usb_rtl28xxu
If you google "rtl sdr blacklist" you'll see several examples of making this permanent.
@madengr , I have the same problem with Ettus b205 board. Any idea how this can be resolved? Thanks.

Does uhd_find_devices work?
@madengr , the drivers work just fine with gqrx, osmocom_fft and gnuradio. If there's any more useful information I can provide, please let me know.

@madengr , sorry for the panic my friend, it seems to be working now. Probably I messed up some system components in the past, and changed it since then. Have a nice day and thanks for stopping by!
