I looked at the specs for the Mercury board, and it's disappointing that it doesn't do complex sampling (at least, according to the diagram). The receiver chips that I care about produce I and Q outputs, but that's just me :-) The HPSDR project does look interesting, and I can see why, for some applications, you'd like to remove the PC from the picture (satellites come immediately to mind). -- Marcus LeechMail: Dept 1A12, M/S: 04352P16 Security Standards AdvisorPhone: (ESN) 393-9145 +1 613 763 9145 Strategic Standards Nortel Networks [EMAIL PROTECTED] ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Hello -- I'm one of the developers working on HPSDR.org - specifically the Janus/Ozy board and the PC pieces inside PowerSDR. As Bob and John have stated we started out trying to build a better ADC/DAC, mostly thinking about using it with Flex-Radio's SDR 1000 hardware. Over time it's turned into a backplane definition and a modular design of some building blocks that can be linked together to play radio. We are certainly aware of GNURadio (I have a USRP and run GNURadio), and have 'borrowed' pieces from it - I believe the cordic from the USRP is being used in Phil Harman's initial experiments on Mercury (wideband 130 Ms/sec A/D converter). We also share common USB interface hardware (FX2) and software (libusb), We differ a bit on focus - GNURadio is a much more ambitious and generic project, most folks interested in HPSDR are interested mostly in amateur radio applications. Also HPSDR at the moment is tied to PowerSDR which is primarily a Windows thing, while GNURadio is most at home on Linux. I don't know of any politics or bad feelings between the two projects. I know some of the folks active here are also active with HPSDR. All the stuff we're doing is open source licensed (GPL/LGPL on the software) so it's exploitable if folks find is useful. I know I'd like to write a gr-audio-janus layer at some time to allow one to use the Janus ADC/DAC board to work with GNURadio - just a matter of finding the time to do it and learn a bit on coding for GNUradio.

They've been working on some innovative h/w, mostly targeted at HF. When they get their h/w sorted out and I can order some, we'll make it work with GNU Radio.

It sounds like Lyle and friends are either not aware of Gnu Radio, or there's some politics I'm not aware of... I don't think that's at all accurate -- if anything, it's a complementary project to GnuRadioP. HPSDR is hardware-oriented and doesn't focus (much) on software. While its comparable in some ways to the USRP, the design is quite different. The inital goal of HPSDR was to create a no-compromise ADC/DAC combination (connected to the PC via USB) for use with the SDR-1000 and similar hardware. The part of the project that's furthest along (the "Ozy" and "Janus" boards) provide that functionality. However, the design is based on a passive backplane (called "Atlas" and already available for purchase) and is very modular in nature, so it's feasible to add all sorts of RF hardware to the mix. Some of those are in the early development stage. There's no reason at all that the HPSDR system couldn't hook into GnuRadio, although for the moment the software testing has been done with a modified version of the PowerSDR software that's used with the SDR-1000. There's really no politics involved at all, just a design that started with the idea of a super-duper sound card replacement and just sorta grew from there. Two additional points: 1. The HPSDR hardware designs will all be made available under an "Open Hardware License" that I'm currently working to develop. It's not quite the same as the GPL since we've discovered that the practical issues around hardware are quite different, but the spirit is very similar. 2. TAPR (http://www.tapr.org) will be making the initial HPSDR modules available (we may do later ones as well, but we're going on a case-by-case basis). Most of the modules are complex enough that they will be offered only in assembled and (somewhat) tested form, but again, all the design files will be available under a license that allows you to reproduce the boards yourself if you want.
