Hi all, For the life of me I still can not figure out how to properly build an AM and SSB receiver. Using grc I am able to build and run FFT sink and observe the AM broadcast band spectrum and control the frequency. But I can not detect the audio. (I have not yet tried to build an SSB receiver.God forbid.) I tried various filters and AM DEMOD. When I install the AM DEMOD I keep getting an error message "number of taps must be >=3." Can anyone tell me how to build an AM/SSB receiver using grc? I have searched the web but haven't found anything. Searching the gnuradio directory I found hf_explorer, hf_radio and usrp_am_mw_rcv.py. These files appear to be what I am looking for but I have not been able to figure out how to install and run them under python. Can anyone instruct me on how to get these files/programs up and running? I have spent hours and hours trying to figure it all out (and searching the web)but so far I haven't been successful. Is there any way to get an HF receiver up and running without the need to become an expert in python, C++, etc? I do want to learn to use python, C++, etc so that one day I can write some blocks but I would like now just to get a receiver up and running to play with.

Hi all With your help I have accomplished the following: Installed gnuradio and able to use grc. (I have the USRP and the receiver boards) I am able to run the FM radio example and it works great. I have also figured how to add scope and water fall sinks. I am having problems in building an AM broadcast band receiver, I am able to set up the USRP source and FTT sink. It appears that the AM band spectrum is visible in the FTT sink. The problems arise when I try to add AM demod and audio sink. My questions are: What grc blocks (and their parameters) do I use to build an AM broadcast band receiver? An SSB receiver? A TV? and a HDTV? I spent hours trying to build the AM receiver to no success. I have also spent several hours searching the web. Is there a web site that presents the grc blocks needed to build the various receivers? Thank you very much, Steve ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Hi all I am making progress. Using GRC and the information from Joshknows.com I was able to build the blocks for dial_tone and got it to work. But I am unable to get the volume and noise sliders to function. I have spent several hours trying to solve the problem but with no success. I'm sure the solution is probably simple but I haven't found it.

[Discuss-gnuradio] another newbie question
Hi all I have re-installed Ubuntu 9.04 and still have questions regarding getting gnuradio up and running. Following these instructions "GNU Radio Release 3.2 With the latest GNU Radio release 3.2, binary package installation is available for Ubuntu 9.04 (Jaunty), bypassing the need for manually installing build tool prerequisites and performing a source code installation. In addition, installation and configuration of the USRP and USRP2 is automated. This is fastest and easiest way to get a working GNU Radio platform. The rest of this page is now somewhat outdated and needs some reorganization. " I went to "Debian Package Repository for GNU Radio" and followed the instructions. Everything seems to have installed corrctly. I am able to open GNU RADIO COMPANION. But how do I get a "working GNU Radio platform" as stated above in "GNU Radio Release 3.2"? Do I have to build it from scratch in grc? Or do I have to still build it from scratch using the "Build Guide" (which I tried without success.)? >From what I can interpret in the first paragraph under "GNU Radio Release 3.2", it is not necessary to build from the "Build Guide" if I have Ubuntu 9.04 and using the latest GNU Radio release 3.2 - I can just use the "binary package" installation. I have searched the web but haven't been successful in finding the information I need. I guess my question is to get gnuradio up and running do I need to build it from scratch using grc or is there a quicker(interpret easier) way of doing it?

Hi all I am using Ubuntu 9.04 and, after some trial and error, installed gnuradio and grc per the instructions shown in "Debian Package Repository for GNU Radio" Do I get gnuradio up and running by building it from scratch using grc or do I have to do the following: $ ./bootstrap $ ./configure $ make $ make check $ sudo make install I am concerned that if I do the ./bootstrap, etc, I am going to be creating problems. (I have re-installed Ubunu several times in order to clean up the problems I had created by my trial and error method of learning.) I have spent several hours trying to find info on the web and gnuradio web site but haven't been able to find something that is simple enough for me to follow. I am a user of HPSDR and have PowerSDR up and running, but gnuradio appears not to be as simple to install and run.

Hi all (using Ubuntu 9.04) I am still having problems trying to get gnu radio and grc to run but I found what the problem is but can't figured out how to solve it. I tried to reinstall everything. When I "./configure" , I get the following message at the end. - "The following components were skipped either because you asked not to build them or they didn't pass configuration checks." gcell usrp gr-usrp gr-gcell gr-audio-jack gr-audio-osx gr-audio-portaudio gr-audio-windows gr-gpio gr-radar-mono gr-wxgui gr-qtgui gr-sounder gr-utils grc "These components will not be built. I attempted to re-install again - same problem Another try - I removed gnu radio and re-dounloaded gnradio-3.2.2. This did not solve the problem. I get the same message when I ./configure. It appears that one of the problems is that gr-wxgui is missing. It doesn't seem to be a package of Ubuntu 9.04. Help!

[Discuss-gnuradio] another newbe question
Hi all I thought I had figured out how to in stall GNU RADIO but? (I'm using Ubuntu 9.04) Following the "Build Guide" and using the terminal and cd'ing to the correct directory, I installed GNU Radio release 3.2 by doing the following: $ ./bootstrap $ ./configure $ make $ make check $ sudo make install This probably took around 20 minutes and everything appears to be installed and checked out correctly. The "Build Guide" doesn't state what the next step is. I can't find any applicable GNU radio program to open. What next? Where do I find GNU Radio and get it up and running? I have come to a dead end and can't figure out what to do next. I guess my 65 year old brain is loosing its gray matter. Thanks for the help.

Hi all I am new at this and slowly learning Linux, GNU and GNU Radio. In following the installation instructions for "GNU Radio Release 3.2", I got as far as "Now edit qwtconfig.pri:" and have come to standstill. I can't figure out this step. I am sure it is elementary to the rest of you but it has brought me to a stop. Can anyone explain this step in detail?
