WELCOME TO HAMBUILDER RADIOWORK HBR4HFS , is another 4-banders series with high power out from Hambuilder. It is a small size desktop transceiver with big power (up to 100W). We try to keep it low cost, simple to operate and easy to maintain. You can also adjust the power out down to QRP level (below 10W). This radio now has built in mic compressor, no need to speak loud infront the microphone. TCXO (temperature compensate Xtal Oscillator) used as source frequency for the digital synthesizer to provide minimal frequency drift cause of temperature. (latest version). Original Hambuilder products are made in Indonesia.
