Multiband beacon with GPS interface for MOBILE and FIXED applications

I have designed and built a versatile WSPR beacon that works on 160m to 6m with up to 15W.
It derives time and location information from a GPS mouse and creates WSPR data locally without the need of a PC.
It has a LPF switch module and a attenuator switch module. It can run multiple DDS/PA modules concurrently.
Initial config is done with a Windows utility over USB. Details on the project are available at

Have a look. I would be happy about comments
