Switched off at 2300z to go to bed...

I'm looking at code to generate  a WSPR signal directly from a DDS/PIC
combination controlled from GPS timing   When done, it will be
possible to leave a beacon running without having to leave the PC on
overnight.

PAs and drivers,  happy enough leaving on unattended as I have control
over their thermal protection etc,
But PCs, although designed for 100% on-time, I don't have control over
their hardware.

Also, PICs driving DDSs aren't prone to crashing
