Max,

I tried to get receivers from 1 nanoHertz to 100 GHz.  Of course all that were available were the 24 MHz-1700 MHz, and then some 500 kHz to 1700 MHz, and a scattering of others that supposedly can get to 6 GHz but cannot get that to reach that range. Working alone is hard.

I want to set up permanent scanners around the world (more practically try to provide software to existing SDR and SDR-like sites and convince them to save their timeseries and FFT streams) to monitor power at all frequencies and synthesize a complete global map of the electromagnetic field of the earth across all frequencies.  

( It was the only way to use the higher frequency power varations to monitor the nanoHertz to 1 MHz region I am particularly interested in. )

But I think it has merit on it own. One group covering all the frequencies globally is easier than thousands of individual groups by location, sponsoring group, software variety, hardware variety.

I tried to convince the SDR software writers to simply allow storing their data to disk, including the FFTs at the best rate their software and computer is capable of doing.  SDR#, CubicSDR, HDSDR, SDR Uno, RSP Spectrum Analyzer, SDR Radio Console, and some oscilloscope and sound card based programs.  I checked the VLSI and radio telescope networks. I checked the RF interference monitoring communities. I checked the power system monitoring groups. I checked the magnetometer, seismometer and gravimeter groups (their instruments all pick up magnetic signals), infrasound, GPS, ionospheric research networks, solar monitoring networks.  And as many of the modeling groups as I could find. School networks for all the above. Hardware and software groups interested in the above.  About 10 million individuals and as many groups.  Not a big Internet group, but hard to do in my spare time.

I went through all the projects you like. We have very similar interests, but you have not posted what you want to do.  I am guessing it has something to do with using inexpensive computers, sensors and real world signals.  You have a focus on radio waves, but are interested in signals generally.  You also want computers to do and change things. You might want to use shaped electromagnetic fields for practical applications in industry and for fun.

I will follow you, but it will be one sided, if you sit on the fence and do not share who you are, what you want to do.  If you will tell me what you want to do, and post it as a "project idea".  I can find things and groups and resources to help you.  I am guessing it is something serious,  I understand play, but mostly do not have the time or energy.

My own projects are nearly impossible.  But I posted them anyway. 

I am pretty old now, or I feel old.  I will turn 71 in January.  I have been working hard since I was a teen ager.  I remember most everything I have ever read or seen.  And I have spent the last 21 years studying the whole Internet and how people are using it.  With an emphasis on effective methods for building sustainable global groups.  I found a few things that will dramatically alter what all humanity can do, but now I am finding I might have taken too long on too many things.
