About:

My name is Tom.

I live in Arlington, VA.

This gal is my wife.

This is my personal page. I have other pages, too, like bearscare.org.

I feel strongly about bears, octopi and dinosaurs. And elephants, rhinos, and some large birds too.

Shoutouts:
My lovely wife Catherine!

An excellent bear resource

Radio/programming victories

In chronological order:

  1. Kicking GNU Radio’s ass
  2. Demodulating a Gaussian frequency shift keying (GFSK) waveform with a Gaussian minimum shift keying (GMSK) demodulator
  3. Learning that the demodulated bits are always inverted for no obvious reason
  4. Writing bitstuff and unbitstuff routines
  5. Implementing proprietary scramble and unscramble routines to make real information look like noise
  6. Learning the signal from item 2 was GFSK and not GMSK, even though it was supposed to be GMSK. 
  7. Creating a GFSK waveform using a continuous phase frequency shift keying (CPFSK) modulator.
  8. Achieving end-to-end, digital communications using items 1-7 with a little silver box which came with minimal documentation.
  9. Writing no-return-to-zero (NRZI) encoding and decoding routines

Hell yeah!
