Hello,
there is now a test sample (bit file) with speech at
http://tetra.osmocom.org/trac/wiki/Test_Samples
Please only add samples to this page if you have the full
agreement for publishing from all involved parties (e.g.
operator of the network, people speaking during the capture).
This is not the place to share captures which were made
from someone else without their knowledge.
Best regards,
Dieter

Hi,
are you aware of problems with that?

Works fine with 3.6.0 on myu netbook so I'm not sure if it's a release issue or I simply have something screwed on the main pc.Cheers

Hi all!
This is the announcement for the 2nd incarnation of our bi-weekly
Osmocom Berlin meeting.
April 25, 7pm @ CCC Berlin, Marienstr. 11, 10113 Berlin
The schedule is as follows:
19:00 Introduction into the TETRA base station located @ CCCB
For quite some time, there is a full TETRA base station located
in the Berlin CCC, consisting of two base radios (BR), a site
controller (TSC), an auto-tuning cavity combiner and other
equipment. The talk will introduce the architecture of the
system and the current status of getting it running.
20:00 Presenting the CC32RS512 / towards an Osmocom Card OS
The CC32RS512 is a flash-based smart card controller to which
the documentation is available without NDA. This means that we
finally are able to implement a Smart Card OS (COS) as free
software.
20:30 Informal discussions
If you are interested to show up, feel free to do so. There is no
registration required. If the initial part is not interesting to you,
feel free to join us later at 20:30. The meeting is free as in "free
beer", despite no actual free beer being around ;)
Regards,
Harald

has anybody succesfully get rtl chipset working? i tried it with every tetra signal
and it always says cannot "find suggestive training sequence" approx 1 sec interval
signal levels are good.tried with many different amp/antenna compination.
and changed filter settings but no change.and with rtl-sdr it seems that it doesent change
gain at all.
i can demodulate tetra good but minimum samplerate i can do is 1msps at 3ghz double core cpu is 100% in use.so i want to demodulate it with lower value. when i try lower value
example 192ksps it doesent work.so im asking any workarounds?im using noxon dab/dab+"fc00013"
is it rtl chip that cannot do under 1msps?and on gnuradio under 1msps fft is very slow but 1+ its normal.
