Image Taken From Our Previous High-Altitude Balloon flight at over 90,000 ft​

Members of the Nashua Area Radio Society will again be launching a High-Altitude Balloon (HAB) to the edge of space and back this Saturday, October 28th at approximately 15:00z (11 am Eastern Time). Our HAB will carry a 2m APRS Transmitter and will send position and atmospheric telemetry to the ground during its flight. Our HAB can be tracked via APRS on 144.390 MHz or via the Internet using aprs.fi. Our HAB will be flying using the call sign N1FD-11.


Predicted Flight Path for our HAB's Flight​

We expect our HAB's flight to last about 2 1/2 hours and cover a distance of approximately 100 km. We are hoping to reach an altitude of over 105,000 ft before the balloon bursts. You can read more about our launch plans and how to track our HAB-2's flight here -

The previous link also includes a high-resolution, full-screen version of the video from our first HAB's flight.


Launching HAB-1​

Our HAB launch is part of a STEM learning project that the Nashua Area Radio Society is doing in partnership with schools here in New Hampshire. You can read more about the project and our STEM work on our Blog here -

Excellent, Fred.

Dumb question - have you considered using the QRPLabs WSPR transmitter for the balloon trip?  Not expensive, transmits on HF, lightweight, can do telemtry.  Some other hams have done it, with success...esp for times when the balloon is out of VHF range.  With the QRPlabs transmitter, they use solar power.  Although output power is in milliwatts, the signal reaches far.
