Here we provide a feature and function overview of the Hardrock 50 RF Power Amplifier from HobbyPCB.com
More details here:
A full build video will be released shortly, for those that want to see how this amp was built using the kit ordered from hobbypcb.com
Overall this is a great 50 watt HF amplifier, suitable for a wide range of QRP radios or SDR Transceivers. Personally I use it with a Hermes Lite 2, with the optional IO Board to control automatic band changing.
