I was thinking the same. But then I thought that the USRP is overkill if you are doing ham type waveforms as they are only 3Khz wide at mosy. A studio quality computer "sound card" can take 192K samples per second at 24 bits per channel.. GNU radio software can interface to a high-end sound card
After the sound card you only need a mixer and a VFO. There are a number of projects that are suplying simple SDR front ends like these. I may buy smething like USRP later but for now I want to get on the air for a lot less, About $40 is all you need for a very limited front end -- RX and TX on a crystal bound frequency once this works my plan is to replace the crystal with a VFO and then figure out how to switch in filters. Don't get me wrong a USRP would be great. --- "Michael C. Menefee" <[EMAIL PROTECTED]> wrote: > Hi folks, > I'm a ham that has become interested in SDR in general, and GNU > Radio/USRP.
