This will be a flight test of my new HF transmitter to test the new configuration of the Trimble Copernicus GPS unit that has failed at 29,000 feet in two past flights (the last occurred at GPSL)....it turns out that there is an undocumented altitude limit of 29,000 feet (curiously enough) when the Copernicus is set for LAND mode. So according to the Trimble engineers, it should work when set up for AIR mode. Hopefully this will prove out as this is a very lightweight, low-current drain and stable GPS unit. 
  
This will be an ozone hitchhiker and will be attached to the weekly ozone sounding balloon from the NSSTC building near UAH Huntsville. 
  
Launch time: 1:00 pm CDT Saturday October 4th. 
Callsign: WB8ELK 
Payload:  1 watt HF transmitter on 28.172 MHz (best heard at 28.171 MHz). 
Mode:  RTTY, Hellscreiber and DominoEX5.
