The first version of the AMSAT-DL down converter was built in early 2019, enabling many stations to become active on QO-100 for the first time.
Since then, a lot of operating experience and new insights have been gained, which have flowed into the new board V3d.
The AMSAT-DL DownConverter V3d is a completely new development.
It offers important functions for all QO-100 stations, no matter if you work with VHF/UHF, HF transceiver, or an SDR. This new board can be used as a central frequency converter assembly for your QO-100 station providing stable clocks for all components meaning that additional external GPS modules are not required.
