About this radio
The Flex-6400 is part of FlexRadio's second-generation 'M' series, introduced in 2018 alongside the 6600M as a refresh of the original SignatureCXA line. It's a 100W software-defined HF/6m transceiver with a single receive slice and an improved ADC over the first-generation 6300, plus a rear-panel touchscreen-ready control head option. Positioned as the budget model of the M series, it's aimed at operators who want current-generation Flex receiver performance without paying for the dual-receive capability of the 6600M or 6700.
