G'day,
I appear to have problems in getting the dbs_rx daughter to work. It may yet
be another OS (NetBSD usb device) problem. Hopefully, it won't be hardware!
Operation of the tvrx daughter board appears to be fine - receiving signals
at around -100dbm sensitivity (is this what can be expected?).
I'm seeing the following errors when running the dbs_debug.py example:
barossa: {57} ./dbs_debug.py
RX d'board A: TV Rx
RX d'board B: DBS Rx
usb_control_msg failed: error sending control message: Input/output error
usb_control_msg failed: error sending control message: Input/output error
usb_control_msg failed: error sending control message: Input/output error
usb_control_msg failed: error sending control message: Input/output error
and when attempting to change the frequency using the slider
usb_control_msg failed: error sending control message: Input/output error
usb_control_msg failed: error sending control message: Input/output error
usb_control_msg failed: error sending control message: Input/output error
usb_control_msg failed: error sending control message: Input/output error
usb_control_msg failed: error sending control message: Input/output error
usb_control_msg failed: error sending control message: Input/output error
usb_control_msg failed: error sending control message: Input/output error
Traceback (most recent call last):
File "/usr/pkg/lib/python2.4/site-packages/gnuradio/wxgui/slider.py", line
20, in <lambda>
lambda evt : callback(evt.GetInt()))
File "./dbs_debug.py", line 129, in set_rf_freq
(success,actual_freq) = self.dbs.set_freq(1e6*freq)
File "/usr/pkg/lib/python2.4/site-packages/gnuradio/db_dbs_rx.py", line 341,
in set_freq
(byte1,byte2) = self._read_status()
TypeError: unpack non-sequence
No signal is detected at any level of input. I also noticed that the MAXIM
chip gets reasonably hot - is this normal?
Those that have it running, can you tell me which version of gnuradio and OS
you're using? This may help me to track down the problem here.
Any help is very much appreciated.
