Hi there,
I saw a message in the July archive (I wasn't subscribed yet at that
date) about updating gr-ais with osmosdr support.
I was working on the same thing recently, so i decided to publish my
fixes on top of Antoine's one.
The result can be found here:
https://github.com/chgans/gr-ais
thanks a lot for sharing your work.
I got it working with both an FCD and an RTL:
ais_rx.py --rate 96e3 --gain 30 --error -17 -d -D fcd=0
ais_rx.py --rate 1024e3 --gain 30 --error -110 -d -D rtl=0
Strangely passing freq_err=XX parameter to the source (using -D),
doesn't work, the use of --error is thus needed (which will do a
set_freq_corr()).
The parameter freq_err was never supported, you may use
rtl_xtal/tuner_xtal parameters for rtlsdr devices only to specify the
real xtal value you have measured, this is almost equivalent to calling
set_freq_corr() function.
Ok, it's good to know.
I've sent a request today to Harald for an access to the Wiki (according
to the instructions on the login page), I would like to update the
GsOsmoSdr page, I think it would be very nice if all the options were
documented, with device specific information and example too.
Chris
Best regards,
Dimitri
