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 sta-
tion providing stable clocks for all components meaning that addi-
tional external GPS modules are not required.
The specification for the AMSAT-DL DownConverter V3d includes:
- Centralized clock generation with GPS or OCXO
- Reference clock for the PLL in the LNB
- Reference clock for a transmit mixer
- Reference clock for an SDR
- Short-circuit proof LNB phantom power
- Connection for a dual LNB (for simultaneous NB and WB reception)
- Downward mixing of the NB transponder into an amateur band
(UHF/VHF or HF) - OLED display for displaying the operating status and the station
coordinates
