Hi Angela, As far as I know, nobody's used that code in quite a while. There is an mc4020 driver that works for 2.4, and more-or-less works for 2.6 (but doesn't properly create dev files). driver: ftp://ftp.gnu.org/pub/gnu/gnuradio/mc4020-0.9.tar.gz old GNU Radio glue code, needs work to fit in with new build system: ftp://ftp.gnu.org/pub/gnu/gnuradio/gr-mc4020-0.5.tar.gz It may make more sense to check out the comedi driver (http://www.comedi.org/hardware.html). I believe it's being actively supported. We do have a gr-comedi package, but I don't think it's gotten any real testing. It may be a good starting point. FWIW, folks prefer the USRP to the DAS4020-12 since it's does a whole lot more (including the RF to IF conversion) and costs less. Of course, if you've already got a 4020...

Does anyone have good pointers for info about GnuRadio running on the MC PCI-DAS4020-12?

Well, all I can think of is using the basic rx daugtherboard along with usrp_wfm_rcv.py and tuning to some local FM stations, or using the scope, but it sounds like you've already done that pretty much. Make sure the gain on the scope is set to about mid-point for the specific daughterboard being used. I had the best luck with this. Depending on your scanning bandwidth, I don't know if you'll actually pick up any listenable stations, so I'd just use the aforementioned file for FM testing purposes.

Re: [Discuss-gnuradio] Help getting started
Well, I've never used the TX boards before, but looking through the files I found fm_tx.py, which makes narrow band fm. You may have to use usrp_nbfm_rcv.py (or whatever it's called) to pick it up, but now I'm just guessing. -Written Dan Halperin wrote: > > Fair enough; I figured since my officemate's pocket CD player could pick > up FM radio the big ole' antenna ought to be able to. > > Is there a script to make a custom FM station using a BasicTX board (I > have another USRP if necessary) to get around that problem? > > -Dan > > Written wrote: >> Well, all I can think of is using the basic rx daugtherboard along with >> usrp_wfm_rcv.py and tuning to some local FM stations, or using the scope, >> but it sounds like you've already done that pretty much.

Re: [Discuss-gnuradio] Help getting started
Fair enough; I figured since my officemate's pocket CD player could pick up FM radio the big ole' antenna ought to be able to. Is there a script to make a custom FM station using a BasicTX board (I have another USRP if necessary) to get around that problem? -Dan Written wrote: Well, all I can think of is using the basic rx daugtherboard along with usrp_wfm_rcv.py and tuning to some local FM stations, or using the scope, but it sounds like you've already done that pretty much.
