[Discuss-gnuradio] Mac OS X Build problem
Hi all, I have been trying to install the latest stable release (v3.1) on Intel-Mac with Mac OS X(10.4.11). I have tried to follow both Jon Jacky and Michael Dickens's build guide, I had different problems. Anyways, the problems can be concluded as follows: 1. Since GNURadio 3.1 requires numpy instead of old Numeric, hence I either have to use python 2.4 installed by macports or I have to make numpy work on python2.4 (I failed to do so, not sure why). 2. I tried to use python 2.4 (import numpy no problem), this is the command I used to build: setenv GR /opt/local ./bootstrap ./configure --prefix=$GR --with-pythondir=$GR/lib/python2.4/site- packages make sudo make insall PYTHONPATH=/opt/local/lib/python2.4/site-packages 3. When I tried to use mac build-in python (2.3.5), with numpy installed the error message I got while running some python script: Traceback (most recent call last): File "sounder_tx.py", line 23, in ? from gnuradio import gr, usrp, eng_notation File "/usr/local/lib/python2.3/site-packages/gnuradio/usrp.py", line 27, in ? from gnuradio import gru File "/usr/local/lib/python2.3/site-packages/gnuradio/gru/ __init__.py", line 37, in ? exec "from gnuradio.gruimpl.%s import *" % (f,) File "", line 1, in ?

I did notice that numpy requires python2.4 or higher, I am not sure if there is a work around or not. Any hint would be appreciated. Am I missing something somewhere? Thanks in advance.

What is good is the mention that the improvements are still compatible with the P25 vocoder standard. The AMBE + 2 part sounds like further improvements to the CODEC over the AMBE2000. The future AMBE3000 will implement AMBE + 2 and it appears compatible with the AMBE2000 and AMBE1000. The AMBE2000 is more flexible in the data rates and when I look at the rate tables on page 29 I see the P25 rate listed with the correct voice and FEC data rates. You can do the same rate in AMBE or AMBE+. So one task will be to figure out how to configure the chip so it will decode P25. 73 Eric ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

[Discuss-gnuradio] DV Dongle - AMBE USB Device
Hello, One of the "problems" with DStar and some other digital voice systems is the Patent and other IP considerations. DStar uses the AMBE codec which is owned by DVSI. Icom uses a DVSI AMBE2020 chip in their DStar products. One possible solution is to buy hardware that puts the Patent and IP into a chip. This increases the cost of the hardware and you need to interface it to the PC. Some chip makers do not make chip information available, but DVSI does. The USER Manual is very informative. http://www.dvsinc.com/products/a2000.htm A group was able to produce a USB Device that interfaces the AMBE2000 chip to the PC. The icing on the cake is it is an open source project. The API appears similar to the RF Space SDR products. http://www.moetronix.com/dvdongle/ The DV Dongle is now in production and even has a website, http://www.dvdongle.com/DV_Dongle/Home.html So I ordered one for $200 from HRO and hope to get it in a few days. It should be possible to add support for it in GNURadio. I am also thinking of writing a APCO P25 Voice to AMBE2000 frame converter and see if the device can decode P25 as well. This may be a general IMBE and AMBE codec. 73 Eric ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
