[hpsdr] Using SDR-1000 amplifier with HPSDR?

[John Ackermann N8UR]

Has anyone interfaced the 100 watt amp (and maybe antenna tuner) from 
the SDR-1000 to work with the HPSDR system?  I am wondering what sort of 
control signals are required for the amp to work independently of the 
SDR1K board stack.

Thanks,

John
