HBR4HF V3.0, is another 4-banders series from Hambuilder. It is a medium size desktop transceiver with big enough power. We try to keep it low cost, simple to operate and easy to maintain. This item actually an upgraded power control of HBR4HFN with previously only providing maximum 25W power out by using 2x IRF520 as the final transistor. Now we can adjust the power out to QRP level (below 10W) if required.
