Amateur Radio Information for TuPOD

The TuPOD transmitted on radio amateur frequencies and the HAM radio community received the satellite signal all over the world!.

The frequency was 437.425MHz with a variation of +/- 10KHz due to the doppler shift. The satellite transmitted a small FM morse beacon that was activated on the 20th of January 2017 at around 0:00 UTC and it lasted for 4 days until the primary mission was completed and the primary batteries depleted. (TuPOD does not have rechargeable batteries nor solar panels).

After the release of the onboard TubeSats, the satellite will rapidly decay due to the atmospheric drag. It is expected to re-enter in a few weeks after the TubeSats deployment.
