Hardrock 500 #eladduo
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.
