Note
The CommRadio CTX-10 is a rugged, ultra-portable QRP HF transceiver designed by AeroStream Communications in Colorado. It is built with a philosophy of simplicity and durability, often described as having a "military-spec" feel. Extremely rugged construction; exceptional battery life and flexible charging; simple, intuitive interface; high duty cycle for digital modes (FT8).
Unlike many modern radios with complex menus, the CTX-10 is designed for "set-it-and-forget-it" ease of use. It features a machined aluminum enclosure that acts as a giant heatsink, allowing it to run at a 100% duty cycle without a cooling fan.
It includes three internal #18650 Li-ion batteries providing about 28.8 watt-hours of operation. It can be charged by almost any DC source between 5V and 20V, including solar panels or standard USB power banks.
Features a built-in automatic antenna tuner (ATU) and an integrated CW keyer/reader, and a high-contrast OLED display that is easily readable in both bright sunlight and low-light conditions.
