My own virtual radar

I'm an avgeek, so I recently setup my own Automatic dependent surveillance – broadcast or ASD-B receiver. There are plenty around. The most common setup is to use a Raspberry Pi with a PiAware image on an SD card, an RTL-SDR and a 1090 MHz antenna. There are also more dedicated setups using hardware provided by the major ADS-B tracking websites such as FlightAware and Flightradar24.

I went the Pi route. However, instead of using the FlightAware PiAware image that's commonly available; I choose to run the ADS-B Receiver image by Joe Prochazka.

My setup consists of a Raspberry Pi 3B, a FlightAware Pro Stick Plus and a cheap $7 1090 MHz antenna. The Pro Stick Plus is nice because it's essentially a RTL-SDR USB dongle with a built in 1090MHz filter and RF amp. FlightAware also offers the regular Pro Stick which does not include a 1090 MHz filter.

I used the dump1090-flightaware version of the image, although it is available with another dump1090 version called dump1090-mutabi…

W1OCY's hidden treasure

W1OCY, Everett E. Chapman, is a silent key. He died in 2010, just two days shy of the new year at the age of 85. He was born on April 30, 1925 in Glen Cove, NY and grew up in Vermont and New Hampshire.

He served his country in the United States Navy during World War II and was part of the V-12 Navy College Training Program at Dartmouth College. He was at least an Ensign based on items we found in this "treasure." I don't know if he reached any higher ranks, I've tried searching through US Navy Registers online and so far, I haven't found anything.

He graduated from Dartmouth in 1948 with an A.B. and entered the business world in 1955 working for Dynatrol and other places in the aerospace industry such as Raytheon based on his collection of papers we found.

He didn't have much family, didn't marry, at least from what I can tell and obviously no kids. He was survived by brother Donald, who is still alive and will turn 90 on April Fools' Day this year.
