Mounting Hardware
This amplifier is intended for installation in a HARDROCK-50 power amplifier to lower the drive requirements or for general homebrewing. The driver amp covers 1.8 to 54 MHz and is not suitable for use with the RS-UV3 transceiver.
The driver kit, as supplied, does not have sufficient filtering to meet FCC Spurious Emissions requirements. If you intend to use the driver amp as a stand-alone 5W amplifier and connect its output to an antenna, additional filtering is required.
Details for using the Driver Amp for use as a stand-alone 5W amplifier are available on the Driver Amp technical information page:
