Yes I did under a previous version of Ubuntu. How do I clean everything and start from scratch? Sent from my iPhone

Unfortunately I have windows in another partition. Don't want to chance messing that up. Any other way to remove everything and start from new other than another install? Thanks Joe Sent from my iPhone

I wouldn't even attempt to clean it.. just install a new build of Ubuntu, replacing the old. I scrapped Ubuntu and went with Linux Mint 16 Petra http://blog.linuxmint.com/?p=2493 64 bit instead. I could no longer stand Ubuntu's stupid desktop environment. If you're installing 64 bit, make sure you have at least 4 gb of ram. gnuradio won't compile with less. Also, prior to installing Pybombs, you need to manually install an audio dependency. See this post http://forums.radioreference.com/software-defined-radio/282056-sdrs-vs-hard… I made over on the RadioReference forums. -Scott

Hi Max. Do I use stable or unstable? Thanks Joe Sent from my iPhone

Would that be the info I sent or the commands to install uhd? Sent from my iPhone

Well I first ran the commands that Max sent me to build the UHD and that seemed to have worked. Then ran the pybombs again and it failed on UHD again. So I then tried to do a clean install of Ubuntu and since I updated to 12.04 the computer will not let me boot from CD. Checked bios and the CD is first for boot but not doing it. Even tried F12 to force and the dual boot screen just appears giving me choices of booting to Ubuntu or Windows only, not disc. Feel now I am totally messed up Joe On Feb 18, 2014, at 4:13 PM, Joseph Cardani wrote:

Well I ran out of computer to install a fresh version of Ubuntu so I can try installing OP25 from Pybombs again. So I may have to buy a new notebook with Ubuntu pre-installed. Would someone in the know be willing to help me until I can get OP-25 installed properly because I really am buying the new computer just for OP-25. I hate to waste my money on a notebook if this is not going to work or I don't have any help. Also another question. Does the P25 trunking work over the USB port or do I need a dedicated serial port? If a USB works I assume I can use a USB-serial converter to control my ICOM radios? thank you, Joe On Feb 18, 2014, at 4:46 PM, Joseph Cardani wrote:

hi Joe - it's not really possible to give a hardware recommendation - in most cases the hardware can be made to work although if it's a very new model sometimes there may be a bit of lag before good driver support becomes availble. As far as serial vs. USB support for channel switching, this isn't so much a computer hardware issue as it is a radio issue - the answer will depend on the means employed by the receiver that is in use. USRP and HackRF take tuning commands over the same channel as the data flow, USB (and/or ethernet, for some USRP models). Other receivers such as those controlled by hamlib and that are equipped with an RS-232 interface would of course require serial support. Don't overlook the availability of the USB/serial dongles - but make sure they have they're at least +/- 9-12V - some may be +/-5V only which is not according to spec... Also - as previously mentioned, none of the pybombs issues you've reported are problems within OP25. The last time you posted an error message printout it was suggested you should seek help on the UHD forums - did you get anywhere with that ? Max

Just tried pybombs again, same error so I posted it on the UHD forum. I'll update here with any help they provide. Joe On Mar 10, 2014, at 7:59 PM, <ikj1234i(a)yahoo.com> <ikj1234i(a)yahoo.com> wrote:

Hi All, Once I get this UHD issue resolved (And I still have not on the USRP-user forum) I plan on buying a USRP. I would like to use it to monitor trunked digital traffic so what option would be best? Option 1 using the WBX directly receiving the signal or Option 2 using a communications receiver such as the ICOM R7000 or R8500 and using the 10.7 IF output feeding the Basic RX? I am looking for the best performance, sensitivity and selectivity, etc. thanks, Joe

Hi Joe Of the two options you've outlined, I'd definitely recommend the WBX instead of LF or Basic RX. If you later decide to use the R-7000 you could hook up a hamitup or other converter. (Note, you'll need to perform the R-7000 AGC mod). With the WBX it will open up a lot of things in the spectrum that would otherwise pass you by, and the full stature of the USRP would otherwise be wasted on a narrowband source... Max

Hi All, I finally found a computer that could be used for a clean install, a Lenovo W500 notebook. Installed Ubuntu 13.10, updated all software, and then did the git clone. Needed GIT so that went fine then ran pybombs. It took over 3 hours and everything went great - no errors. OP25 was the last programs. I then ran the env and got the following file: /home/joe/target/setup_env.sh I ran the source /home/joe/target/setup_env.sh in the terminal (in the pybombs directory like the last few commands). Took a second and then the prompt reappeared. Is this what I should have done or do I have to run the source command somewhere else. So close!!!! thanks, Joe

Hi Max and everyone, Thanks so much for your help! I will test what you said below today. Definitely getting a USRP1 with WBX as you suggested. I am thinking about also getting Matlab home version and a few other add ons. I heard the USRP1 is not supported by Matlab directly but KIT's Simulink-UHD does. If I do get Matlab home, would that be helpful to the OP-25 community? Does anyone else here have Matlab? thanks, joe On Mar 14, 2014, at 9:38 AM, <ikj1234i(a)yahoo.com> <ikj1234i(a)yahoo.com> wrote:

Hi Matt ! Pleasant surprise to run into you- here's my interpretation of the issue with uhd: the version of libusb that comes with stock ubuntu 12.04 doesn't define the symbol 'libusb_error_name' - consequently uhd fails to build. This is all in a pybombs context, btw. It appears that symbol was defined somewhere around version 1.0.9 of libusb which is newer than what's included in ubuntu 12.04. Ubuntu 12.04 is listed BTW on the ettus.com site as being one of the supported releases for uhd. The net-net for end users is that on ubuntu 12.04 if the user attempts to issue the command pybombs install gr-op25 on a clean ubuntu 12.04 box there is a failure in the step where uhd is being built... Let me know if I can furnish any other details or if the above is insufficient / unclear Best Regards Max

Hi Marcus, Yes the libusb version was less that 1.0.9 that was already on the computer, probably from an failed install done several years ago. thanks, Joe On Mar 14, 2014, at 11:42 PM, Marcus D. Leech wrote:

Hi Matt, Thanks so much for the suggestion on the WBX. Max also said the same about the WBX over using the ICOM's IF out with the Basic RX board. The issue was installing OP25 and it's dependencies using the pybombs script. When attempting to install UHD the script was looking for one of the libusb so files and bombed. I found out that libusb was already there but the file that was a link (simlink?) and this caused the error. I tried to build the latest libusb from source but for some reason the make file was missing which was strange. The computer was a desktop that had been upgraded from ubuntu 10.04 to 12.04 and there were several unsuccessful attempts of installing OP25, UHD, etc. Forgive me but I am not a linux expert so my terminology could be off. So yesterday I decided to scrap the old desktop and install 13.10 on a notebook. That went fine and then I ran the python again to install UHD, GNURadio, OP25 and dependencies. That appears to have worked without error. I still have to do some checking and testing but so far things look good. I will order the USRP and daughterboard hardware sometime next week once I can confirm everything is working fine. thanks and have a great weekend, Joe On Mar 14, 2014, at 11:03 PM, Matt Ettus wrote:
