Hi All,

With the second activation now complete, we are developing a way forward
for more permanent transponder operations.

The activations have given us insight into the performance of the
transponder systems, with the following noteworthy observations

- The uplink frequency is higher than the published numbers
- The satellite is power negative with the transponder running
- The transponder is very usable once the up/downlink relation is
- Resets do occur and the behaviour has to be further charaterised

We are discussing multiple ways of scheduling the transponder operations.
As of now, I can not confirm when we would activate the transponder again.

I would like to thank everyone that participated for their reports and
special thanks to the satellite operators in Delft for running these
experiments for us.

73 and happy new year

Wouter Weggelaar, PA3WEG
