I'm pleased to announce a major new OP25 release, which may be downloaded at http://mattrobert.com/Wireless/op25-gr3.7-0.01.tar.gz
The code has been completely reorganized with the following key changes:
1) This release of OP25 is compatible with GNU Radio version 3.7 (or newer)
2) The build system has been changed from autotools/autoconf to cmake
3) Support for gr-osmosdr has been added. This means that (in addition to USRP support) hardware support is extended to all devices supported by osmosdr (see http://sdr.osmocom.org/trac/wiki/GrOsmoSDR for a complete list of supported hardware)
4) Experimental trunk tracking support for IMBE voice channels now included (optimized for LSM/CQPSK) in the signal scope application
Not all pieces (in particular the python scripts) have been converted to the new format yet. Other pieces (for example the Wireshark plugin) should continue to be downloaded from the SVN repository while we work on pulling them into to the new codebase.
Please excuse the mess - we're working to make improvements and this release is the first step in that process. These code updates will be released as tarballs for the interim period until we can our GIT repository is established. Please notify the list of questions or problems with this new release.
For more information about the trunking and voice support which has been added to the scope.py app see the wiki page at http://op25.osmocom.org/trac/wiki.png/wiki/SignalScopePage
Hey guys,
Can anyone please explain to me what is going on in bch.cc? I am trying
to figure out what ECC is used in there and where it is used exactly.
Thanks

Hey guys,
I deleted my whole op25. checked out a new one. applied Balint's patch,
made some simple changes to the hdu.cc ldu1.cc ldu2.cc and tdu.cc files,
and built with no errors at all. the changes i made:
string
hdu::duid_str() const
{
cout << "HDU";
return string("HDU");
}
string
ldu1::duid_str() const
{
return string("LDU1");
cout << "LDU1";
}
string
ldu2::duid_str() const
{
cout << "LDU2";
return string("LDU2");
}
string
tdu::duid_str() const
{
cout << "TDU";
return string("TDU");
}
all i get in terminal when i hear the noise is a few HDUs. No LDU1s or
any of the others. There should be like 400 "TDU's.
I have been unable to figure what i am doing wrong. Any guidance will
be very much appreciated. Thanks.

Hey guys,
Is anyone getting garbage in the traffic pane UI? I deleted my whole
op25. checked out a fresh version. r328 if i remember right. did the
whole bootstrap, configure, make check, sudo make install dance; and i
am getting garbage in the UI. my logfile looks like this:
2013-11-04 11:02:15.797525 HDU Unknown (0) 0xb13f Unknown (0xc4) 0x5f73
2013-11-04 11:05:10.612410 HDU Unknown (0) 0xed38 Unknown (0x9) 0x73f5
2013-11-04 11:09:21.108211 HDU Unknown (0) 0x8100 Unknown (0x77) 0x1dec
2013-11-04 11:09:21.108955 HDU Unknown (0) 0x61 Unknown (0xa5) 0x7300
2013-11-04 11:09:21.281898 HDU Unknown (0) 0x2ba6 Unknown (0xff) 0x63f7
2013-11-04 11:09:21.460865 HDU Unknown (0) 0x63 Unknown (0x8) 0x7100
2013-11-04 11:09:21.650893 HDU Unknown (0) 0xae6f Unknown (0x7c) 0xed67
2013-11-04 11:09:21.834137 HDU Unknown (0) 0x85 Unknown (0x19) 0x6500
2013-11-04 11:09:22.022031 HDU Unknown (0) 0xf984 Unknown (0x6) 0x360c
as you can see, none of these fields are good data except the date/time.
the HDU should only show up once in while. So something is repeatedly
putting "HDU" and the nonsense data onto the thread to the GRC. In
addition to that i did a:
string
hdu::duid_str() const
{
cout << "HUD\n" ;
return string("HDU");
}
in the hdu.cc and as expected i hundreds of "HUD"s print in the
terminal. so similarly i did a:
string
ldu1::duid_str() const
{
return string("LDU1");
cout << "LDU1\n" ;
}
in the ldu1.cc. and i get no "LDU1"s in the terminal. Ive done this
whole routine 3 times and have got the same result. something weird is
going here that was not with previous versions. like i said the HDU
packets should only come up once in a blue. it would seem that
snapshot() is firing off way to many pickles without getting the right
data in to them.
i have not been able to figure what i am doing wrong here. can someone
please do a fresh install and see if the snapshot() and the traffic pane
play nice for them?
Thanks
