[Discuss-gnuradio] Can't get SDR Transceiver running

[Matthias Weber]

Hello everyone,

after a long period of time I digged out my USRP1 again. What I want to
do with it is some testing in the field of HAM Radio. After some
research I came across the "Software Defined Radio Transceiver" project
[1]. I downloaded Ubuntu 9.04 (Jaunty) which seems to be supported here
quite well and installed it. Next step was to get GNU Radio running so I
used the binary installation which seems to have worked also quite well.
Some final work for the USRP hardware and everything almost worked so
far without problems (there was one more with the USRP connection but
this also got solved). The usrp_benchmark worked.

I downloaded the SDR Transceiver project files v1.0.4
("sdr_transceiver_1.0.4.tar.gz") from the link below, read the manual
and so on. I opened the command prompt and started "./gui.py" which also
worked quite well. But: it doesn't work! The first GUI window looks
good. It is for selecting the mode (AM, FM, SSB, CW). But after pressing
the "Select" button no FFT GUI comes up with all the sliders, text boxes
and stuff. I also tried to edit the config_XX.py files.

There must be a problem calculating the residual frequency!

Would be great if you could help me as I don't have any experience with
python.

I've got a 32-bit machine running with Ubuntu 9.04 (Jaunty), a BasicRX
extension card in the slot of RXA (so far no TX board, maybe someone has
a cheap one?). But at the moment I rather think this might be a software
problem.

Any help? Thanks!

Best regards,
Matthias
