[Discuss-gnuradio] testing outside building with our USRPs

2008-11-30 Thread Bill Stevenson
Hello, all! We are utilizing USRPs to test the transmission range under some certain circumstances, say different modulation schemes. We are planning on testing the range outside, say in a football field since that condition is similar to the free space environment. But how can we get power f

Griff - The DTMF support for OpenBTS won't do you much good. GSM dosn't really send in-band DTMF but uses out-of-band messages to indicate keypresses. Ticket #318 is about implementing those messages. Not the problem you're trying to solve. -- David ___ Sent with SnapperMail www.snappermail.co

[Discuss-gnuradio] DTMF, AFSK1200 gnuradio block

2008-11-30 Thread griff
Hello all: I'm new to gnuradio. Is anyone working on a gnuradio block that can detect DTMF tones, or 1200 baud AFSK (packet radio)? Can this be done (in python) using existing gnuradio filter blocks? I've been using multimon (http://www.baycom.org/~tom/ham/linux/multimon.html) to decode DTMF, e

Re: [Discuss-gnuradio] Transmitting data from file using benchmark_tx.py, recieving to file with benchmark_rx?

2008-11-30 Thread Francesco B.
Perhaps explaining progress thus far would be in order. Currently I'm using tunnel.py to establish an IP connection between two computers (as it was intended for), and manipulating said connection by using a unix pipeline and the scp command in two locations. This works, but doesn't seem the most
