The contacts will be valid for:
- the ESA Amateur Radio Award (2 points per first QSO per mode and band)
- the URE Diploma Municipios Espanoles (DME). Reference Cebreros 05057

QSL policy:
- Electronic QSL:
All the QSOs will be uploaded to LoTW, eQSL, Clublog,HRDLog and
02/11/2017: Upload completed
I prefer electronic QSLs as they are faster, cheaper, easier to archive and they are more friendly to the environment.

- Paper QSL:
I will also support paper QSL both via Bureau and Direct (in both cases via DL0ESA). (Thanks to DARC F42 Griesheim).
If direct, please include SASE (1 USD Europe, 2 USD outside Europe)).
Please note that we will only use paper QSL to reply to the paper QSLs we receive in Germany.

02/11/2017: Paper QSL design in process. Direct & bureau mailing expected/planned in January 2018

The cluster spots statistics for EG1ESA can be found here. Thanks to all the ham radio colleagues who spotted us! Some days the pile-up was quite challenging... but of course also lots of fun!

Last night at the station we also did some ham satellite tracking!
