It also serves as an affordable platform for traditional ham radio use. This model features an improved tuner design with a 0.5 ppm TCXO (optional), providing stable frequency accuracy with minimal drift, high initial offset precision, and tight temperature deviation tolerance. Enhanced component tolerances and MCX connectors contribute to better performance and durability. A USB 2.0 port is required for operation, though it can typically work with most USB 3.0 ports. Please note that compatibility cannot be guaranteed across all USB 3.0 implementations; ensure your computer has a USB 2.0 port if needed.
