The second project is already part of flight radar 24. One I tried to do a while back but didn’t have enough DSP chops for was a SSB tuning correction plug-in.

The second project is already part of flight radar 24. One I tried to do a while back but didn’t have enough DSP chops for was a SSB tuning correction plug-in. If you mistune SSB (LSB/USB), the voices will be off and have a robotic chipmunk sound to them. You can find the correct tuning by looking at the frequency relationship of the fundamental and first two or three harmonics in the voice. But it’s pretty tricky because teaching that while someone is talking is a handful. Limited interested audience for that one though. A mobile TEMPEST attack app would make some waves. A mobile DECT scanner would also be interesting but a bunch of work.
