Don't you then have to buy the $500 RF amp board too?

Just got this today, 

This is a HF RF amp that works with the Elad 5 watts in 500 watts out with an antenna tuner…

It’s a bit pricy at $1,200.00

Just a note that the Hobby PCM Hardrock 500 Power Amplifier Support Kit is now available for sale.  The support kits contains everything you need to home brew a 5w to 500w amplifier.  I have completed mine, and it works beautifully with the Elad FDM-DUO.  With the FDM-DUO set to 5 watts it will drive the HR500 makes 500 watts to the antenna.  Using the FDM-DUO interface from Hobby PCB the amplifier band switches with the DUO.    

A internal antenna tuner will be available shortly for the HardRock 500.

This combination makes for a great and compact portable station with a big punch.
