I built my QDX vsn 1 from the first batch for 9 volts.
Steve,
Like Evan I've built mine for 12 volts, run them at 7.5 volts.
As I only want 1 watt for WSPR I also have 2 or 3 diodes in series with L14.
4 version 1s, run this way obviously no problem, no PA mods.
I run with WSJT-X, one on a Raspberry pi.
(I also run a U3S at <100mW for 17-10m, don't think more is needed.)
Has anyone tried using the QDX with a microcontroller for WSPR?
Do you want RXTX? I guess the WSJT-X functions could be put in a micro, I do not remember anyone doing that as a separate project.
