A consideration here is to wonder if any spurs, etc., get
amplified with the amp. May need more LPF's to keep it
within FCC specifications. Just a thought.

Right, the module seems to be sold by many
different sellers in asia. Dont expect to get documentation
or service, they just sell it.
The boards are named "XF-P100" and
"XF-LPF-HF".  
I
am not promoting these modules as the amp can be changed to
whatever you like, i just wanted to control it via i2c using
Arduino.


@Timothy: I have tried to run in on 24V and my
Zetagi HP500 showed  90W output with 5W drive. Given the
MRF186s specs, wheres the catch ?
