Re: [Discuss-gnuradio] GRC runtime crash

2007-08-27 Thread Josh Blum
Well the error is coming from inside the call to gtk.main(), not directly from any calls in the GRC source. When you press the execute button, it does a call to os.system and a thread waits for os.system to return. When you press the stop button, you are actually are calling a kill -9 on the r

[Discuss-gnuradio] Trunk check-in dependency file breakage

2007-08-27 Thread Johnathan Corgan
I have recently checked in the updates to the hierarchical flowgraph code as outlined in a previous email. One of the changes is that there are no longer any gr_runtime.* files as this class has been removed from the code as part of an API change. However, due to the somewhat broken way we handle

[Discuss-gnuradio] GRC runtime crash

2007-08-27 Thread Ed Criscuolo
While using the GNU Radio Companion, I've been getting frequent crashes. They always occur after terminating a flowgraph that has been run from within GRC. After terminating the fg, there is a few second pause, and then GRC quits. The error output on the cli where GRC was launched is: /Users/ed

[Discuss-gnuradio] Non-QFN Cable Tuner ICs suitable for SDR

2007-08-27 Thread Prasanna Rao
Most high-end cable tuner chips are in QFN packs. I am in search of a manually solderable tuner IC which can provide good IMRR over 50-400 MHZ range for my SDR project. I got hold of TUA6020 from Infineon Tech and TDA65xx Philips Tuners in TSSOP packs. However, they seem to have poor IMRR. I dont w

Firt of all, I think that the chances that you'll find a cell phone running an fm demodulator for GMSK demodulation are very slim, and if they do use it, shame on them ;-) It is the worst way to demodulate a GMSK signal in a GSM environment... Achilleas On 8/23/07, Jeffrey Karrels <[EMAIL PRO

[Discuss-gnuradio] Incompatible trunk check-in pending (for gr.hier_block2 users only)

2007-08-27 Thread Johnathan Corgan
For those who are experimenting with or testing the (unreleased, undocumented) new hierarchical flowgraph code, I am about to check in an incompatible change. (Most people can ignore this message.) As a final API change to the code for its official introduction in release 3.1, the interface has be
