Well the plot thickens. I shot off an email to Freeflight systems asking if they do in fact suppress entry into anonymous mode for a set time period....Received this reply today:
“When Anonymous mode is active (pilot actuated switch) the FDL-978 broadcast the ICAO and the Flight ID for the first 90 seconds after the unit is powered up. After this time the FDL-978 will broadcast a self assigned random temporary address for the ICAO and no Flight ID as long as the Squawk code is set to 1200.
Ok, so if I read correctly, an FDL-978 owner is not anonymous for the first 15 seconds after start up....and FreeFlight considers it to be a requirement.
So, back to the GDL-82. Assume pin 5 is switched to ground, switch closed, 1200 squawk at power up. Is it anonymous from the first instant, or does it broadcast the aircraft ICAO code and N-number for some given time period, before generating a random code?
