I recently looked at internet information on radios like the Pegasus SDR (software defined radio) and the open-source QuickSilver QS1R. It looks like they are making quick progress in developing better radios.
One of the many benefits would be to record radio spectrum. Currently the max is 800khz (possibly 1 mhz), but this could be increased in the future. I'd guess within the next 10 years they'd have it be able to record the entire fm spectrum.
Another huge advantage is that you can watch a larger chunk of spectrum than you can record (I think 30 mhz) - which would be great for ES openings.
Can either of these be used on FM?
For the QuickSilver model - it seems like someone could write code for FM stereo, rds, a wider fm bandwidth, though not for HD radio as it's a closed standard.
