There are alot of linux-based stuff around. A couple I was/am involved with include: Hamlib is a library not only to control ham rigs but receivers and scanners as well. A number of Linux programs use it to control the radio and there are generic receiver control applications in Linux. http://hamlib.sourceforge.net/ The SWLFest has talked about Software Defined Radio (SDR) in the past. The SDR toolkit under Linux is GNURadio. It can also be compiled for Windows and the Mac. http://www.gnu.org/software/gnuradio/ The really neat hardware to use with GNURadio is the Universal Software Radio Peripheral. http://www.ettus.com/ It would be neat if you could get Matt Ettus to talk about it although he is in California. Another SDR guy is over in NJ, Bob McGwier, N4HY. I found a lot of hams involved in AMSAT and TAPR are also involved in GNURadio and other Ham SDR projects. There seems to be better SDR hardware being designed every year. I have done two neat receivers with my USRP so far. They really show I am a VHF/UHF listener. The first is a SCA Receiver that was done by modifying the FM Broadcast receiver sample. The SCA Receiver is also a sample program as my first contribution to GNURadio. The second is a 1090 MHz receiver that receives ADS-B and Mode-S data frames from Aircraft. This is more complex, required some new building blocks, and is not finished yet. 73 Eric _______________________________________________ Swlfest mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/swlfest To unsubscribe: Send an E-mail to [EMAIL PROTECTED], or visit the URL shown above.
