DHS has spent $430 million over the past nine years to provide radios tuned to a common, secure channel to 123,000 employees across the country. Problem is, no one seems to know how to use them.

Only one of 479 DHS employees surveyed by the inspector general’s office was actually able to use the common channel, according to the report. Most of those surveyed 2014 72 percent 2014 didn’t even know the common channel existed. Another 25 percent knew the channel existed but weren’t able to find it; 3 percent were able to find an older common channel, but not the current one.

The investigators also found that more than half of the radios did not have the settings for the common channel programmed into them. Only 20 percent of radios tested had all the correct settings.
