This is so he can pipe the output into Alberto's SDRADIO program and demodulate the wideband modes (AM/FM/SSB) in DSP. A question arises would there be any applications at LF? I'm thinking it might be useful for PSK type signals but not sure on this one. Alberto, Wolf, any thoughts on this one? -- 73 Warren K2ORS/WD2XGJ FN42hi http://www.w4dex.com/wd2xgj.htm
