In Orbit, Unknown Status:
| Satellite | Uplink | Downlink | Comments |
|---|---|---|---|
| TEVEL2 Constellation | 145.970 MHz | 436.400 MHz | The Tevel 2 satellites have 3 groups of software versions. Unfortunately, all of them are suffering from issues that are related to software. There are random restarts that also shut off the transponders. There were reports that indicate some audio distortion that might be related to center frequency deviation. We were unable to solve these issues and therefore can not have a reliable transponder operation. We are still working on the issues. |
