Several weeks ago, we posted a message seeking information about time sources.? There were many helpful and educational responses. An excerpt from one of the responses is included below.? We have been following up with regard to how SDR capabilities might be used for obtaining time using SDR dongles as well as using the time source product referenced in that response. Our SDR investigation has yielded many sources of information, but not a source dedicated to CentOS support for SDR products. Is there a CentOS subgroup and mail li...

I gave myself a toy, one of those cheap USB Software Define Radios, and would like to use it on my C7 box. Having wasted some time on it, I gave up and installed Ubuntu on a USB HD so I can boot that to play with SDR. The Ubuntu GQRX installation is well documented and went off without a hitch. but I just hate having to boot something else on my main box (partly because it also runs a mailserver for my personal domain, partly because, well, I just want my box running CentOS, not Ubuntu.)

Is it a Realtek chipset? I've had problems with it on CentOS as the system will load up the DVB drivers (for TV tuner) thus interfering with the SDR. What worked for me is blacklisting them & reboot. Give it a try. cat /etc/modprobe.d/blacklist_rtl.conf blacklist dvb_usb_rtl28xxu blacklist rtl2832 blacklist rtl2830 BTW there's a new package at http://li.nux.ro/download/nux/tmp/gqrx7/ if you care to test and confirm success so I can...

Another SDR user here. It was me who reported the bug where total samples wraps around on overflow. FLAC performs extremely well on SDR samples, both speed and compression ratio. In my testing it outperforms any other free lossless codec by a large margin, being 20% smaller and 10% faster than the next best (...

It would make far more sense to get a dedicated WWV or GPS reciever to use as a time reference, unless you're going to dedicate a server just to be a software radio. -- john r pierce, recyc...

...this morning, I started wondering if there was something going on, hardware-wise, on the box.

I'm running Samba 3.32 on UbuntuServer 9.04 with both Ubuntu and Windows clients as guests. For some common shares I have create mask = 777 and force create mode = 777. This works fine except that when I *replace* a file on this share by certain methods on an Ubuntu client, the permissions get set to 733 (-rwx-wx-wx), so the file is then unreadable (and undelete-able) by a guest. The

I've been monitoring CPU temperature on a few Dell SC1435s running CentOS4 via OpenIPMI and 'ipmitool sdr'. It's been working very nicely, but the upgrade to 4.5 not so long ago seems to have broken something: # ipmitool sdr type Temperature Temp | 01h | ns | 3.1 | Disabled Planar Temp | 04h | ok | 7.1 | 30 degrees C Temp Interface | 53h | ns | 7.1 | Disabled...

I am not an SDR user, but I think it would be a great idea to design and register an application metadata block for FLAC that supports these needs. The fields in this application-specific metadata block could document how many files there are in total; which file in the sequence the current file is; what the actu...

This could be completely ignored by regular audio players - these files are not meant to be listened to anyway. I could probably figure out how to implement that, I even started looking into it once, but I realised that 1. nobody would adopt it if it is just me behind it and 2. I don't know en...

Hello, We've been using Opus for VoIP calls in Jitsi and we're very happy with the sound quality it provides. Thank you for the great work! We are thinking of updating to 1.1-beta and wanted to know if there's any reason not to do so at this point, and wait for the 1.1 release instead. Is the beta expected to be as stable as the 1.0.x series, or are there any known flaws still to

...ac just returns the correct total sample value you can just recompile libflac on your system and it will work. Additionally I think there is one issue: there are only 31 bits for the frame number, with a frame size of 4096 this is "just" 2^43 samples, which maybe not enough in every case (SDR with higher sample rate?), and smaller frame sizes are possible. And for variable block length it's again 2^36. Of course in combination with the last seekpoint this could work, but without a seektable it's again problematic. Best regards Stefan
