The CommRadio CTX‐10 was designed to be rugged and user‐friendly, with a minimum number of user interface interactions to produce the desired system functional change. Built-in replaceable 3 x 18650 Lithium‐Ion batteries (4.2V @ 2.6Ah) provide power for a day's casual operation. The ability to provide operational power and simultaneously recharge the batteries from any min-5VDC to max-20VDC source provides low‐cost portable expansion capability and unlimited field operation. Features as wide‐range Automatic Antenna Tuner (ATU), CW keyer and CW reader provide everything amateur-radio operator need for full functionality in one lightweight, die‐cast aluminum package with no need for supplementary cooling solutions during high duty cycle operations.
