Theoretically, yes, but you'd still need the power amplifier and the studio mixing equipment. > Would there be significant cost savings involved? No, it would probably cost more and be harder operationally. And you'll very likely need FCC type-approved equipment. > If the code has been developed (this looks interesting: > http://kd5zaa.cafe150.com/sdr/), is this platform stable enough to > run a real radio station? Probably not. I haven't heard of anyone achieving anything like 30s/year downtime with GNU Radio. The main strengths of software radio are the ability to do new things by changing software, and to vary behavior (modulation, rates) adaptively. Neither is important for your application, which is to produce a signal specified by the FCC and unlikely to change. I would suggest that you find someone who understands broadcast radio engineering.
