Legendary HobbyPCB support
The FCC does not allow the commercial sale of power amplifiers that operate below 30MHz with gain in excess of 15 dB. The Hardrock-500 is a project that involves the purchase of two products; a HobbyPCB Hardrock-500 amplifier support package and an AN-1819 amplifier board made by RF Power Tools. Both products are available from HobbyPCB.com
