So I bit the bullet and purchased one of these CR-1a radios from Commradio. The CR-1 is a rugged, small, lightweight, low power, line or internal battery-powered HF (0.5 – 30MHz) receiver. Additional frequency coverage is provided in the LF, VHF, and UHF ranges per specifications.
The CR-1 is a true Software-Defined Radio incorporating a 32 bit DSP allowing software upgrades. Brought to you exclusively through Universal Radio (who have now shuttered operations).
