[hpsdr] Which 100-Watt Power Amplifier for HPSDR?

[Bob Mahrenholz]

Hi:

In checking the http://openhpsdr.org/  "roadmap", I find that the 
SOFTWARE description for POWERSDR-WINDOWS calls out
the HERCULES amplifier from NT-Electronics for the 100-watt power 
amplifier for HPSDR.  Doing a  Google search reveals no
current source from which to purchase this unit.

The HARDWARE description on the same "roadmap" lists the MUNIN for 
the 100-watt power amplifier and states that TAPR is
considering offering a "kit of parts" for MUNIN.

What is the current status of each?  Which will be compatible with 
Pennylane?  Which one should I be saving up for?

Thanks,
