The recent shoot down of the large Chinese spy balloon is nothing new. There is a proud history of Balloon Busters. The F-22 that shot down the Chinese spy balloon had a radio callsign of “Frank01” in honor of Frank Luke WWI Medal of Honor winner.

AG6NS-11 has been waking up every morning with new position reports. Unfortunately, it is not reporting it’s altitude. Using NOAA HYSPLIT to work backwards, it appears to be at about 50,000 feet.

We are launching AG6NS-11, Saturday April 22 at 8:00 am at Cannery Park. We are test flying Kazu AG6NS’s new Raspberry Pi RP2040 based GPS 20 m/2 m beacon. It will be sending on 20 m WSPR only and will be transferred to APRS.fi as AG6NS-11. Please join us. Track it here: APRS.fi
