The TEN-TEC RX-400 receiver recently got a stamp of approval from the FCC, but what kind of receiver is this?
It has receiving range from 2-3000 Mhz (cellular blocked) and a lack of buttons and a display.

The manual is not quite helpfull on how this receiver works, but the TEN-TEC website provides some more information.

At was not immediately apparent of control software is supplied with the radio.

Some additional pictures here, manual here.

FCC ID: ‘DJ7-400′
