[Discuss-gnuradio] Release, website, and other notes.

2005-06-24 Thread Lamar Owen
With all the changes and bugfixes that have percolated down CVS, do we think we might be getting close to a 2.6 release? Along those lines, I have not as yet had a chance to work any on the website; I have not forgotten about it, and intend to work with it. On other notes, one of my projects wi

[Discuss-gnuradio] Multimon (POCSAG/AFSK/DTMF/ZVEI) decoder

2005-06-24 Thread Urs Schaufelberger
Hello everyone! Under the link below you can find my first attempt of porting Tom Sailer's good old multimon to GNURadio: http://ignore.net/~gandalf/gr-multimon-0.1a.tgz It should deliver POCSAG (at rates of 512, 1200 and 2400 baud), DTMF, ZVEI and AFSK (also at different baurates) decoders to

[Discuss-gnuradio] How to stop FFT from going "uOuOuO"?

2005-06-24 Thread Urs Schaufelberger
Hello everybody, Is there a way to stop the FFTs from going uOuOuO all over my stdout? I haven't looked at the guts so far, but it seems a rather odd (and on my side, rather unwanted) behaviour. I'm currently writing a few decoders where the decoded stuff is dumped to stdout, so the uOuO stuff

If I get bored (not likely), I would like to try isosynchronous transfers over USB. My thinking is a dropped packet is no worse than a burst of interference. For radio links, the higher level protocols are already handling error detection and correction. Philip On Fri, 2005-06-24 at 09:32 -0500,

Lets say that we use UDP/RTP. Most non connection-oriented protocols involve an application layer connection control scheme. For TX, each packet has a number and the device NACKs a packet if it is received when the buffer is full. The host then retries NACKed packets at a given interval and give

Re: [Discuss-gnuradio] Interpolation Issues

2005-06-24 Thread Prateek Dayal
Hi, Can you try a few things --> 1. Do not interpolate the signal right now for video ... low pass filter it with a cutoff of some 3 Mhz and then do an AM demodulation, extract the timing information and display the monochrome video. It will not be very sharp but will be good enough 2. Instead o
