💡 What is a linear amplifier used for in ham radio? Linear amplifiers increase the power of outgoing signals so your transmissions travel farther and clearer on crowded bands. - Operators often add them to handheld or QRP rigs to reach 70 watts and punch through noise - They support multiple modes like SSB for voice contacts and CW for digital work - Simple assembly and 13.8V power make these kits popular for portable and home stations alike
