A Bit of History: The company who brought you the CR-1, CR-1a, and the CTX-10 was AeroStream Communications Corp. of Golden, Colorado. The tradename CommRadio was adopted for amateur radio products. Don Moore, W0CTX, is the owner of AeroStream, CommRadio, and all associated Intellectual Property (IP). Prior to developing the CR-1, CR-1a SDR receivers and the CTX-10 HF transceiver, AeroStream developed successful Software Defined Radios (SDRs) for military and general aviation. The foray into amateur radio products started in 2012 after AeroStream completed projects for Special Operations Command (SOCOM), Universal Avionics Systems Corporation, Harris Radio, and others (all standalone SDR receivers and transceivers).
The CTX-10 was a joint venture between AeroStream/CommRadio and Aspen Electronics Manufacturing (AEM) in Westminster, CO. CommRadio invested it's CR-1 and CR-1a IP and developed the balance of the RF and digital circuitry, and embedded software. AEM invested in tooling, components, manufacturing, and warranty service.

The CR-1 and the CR-1a were very successful, rugged HF-VHF-UHF SDR-receivers, with no tether to a PC for signal processing, much like AeroStream's military projects. With an internal Li-ion battery and smart charger, the CR1-!a can operate up to 10 hours on a single charge; drawing less than 1 Watt energy. Perfect for small solar arrrays. The CR-1a completed production in 2016 with final sales into 2017.
