Hi Marcus,
after your current discovery of the gory details, you might want
to consider calling the station on it. better yet send them a post
card!
They might not even know there is a problem, if you can provide
the stations manager/engineer a picture of the problem. It's
usually enough to light a fire under their arse to correct the
deficiency. Many stations are looking for an edge in the market,
properly tuned equipment goes a long way to improving the
experience and their bottom line.
Even a 1st gen USRP is worlds more advanced then the diagnostic
tools available when most radios stations were in their
construction stages.
Yup, that doesn't surprise me.
I just sent a quick note to them saying "WTF guys?".
I applaud your efforts to write a better decoder! of the little
bit of research I have done about RDS and HD radio here in the US.
Both are phase locked and cycle specific to the pilot oscillator.
I haven't looked into it that much yet. There *was* a gr-rds module
written a few years back, so maybe I'll find it and see if I can
integrate it.
If you are going to continue your efforts, I am going
to ask that you Please also write an encoder.
who knows maybe it will lead to better station equipment!
Hmmm. Maybe. I know that Gnu Radio + UHD + USRP has been used in
Europe for production DAB/DAB+ broadcasting in the past
year.
