The Front ViewThe WJ-8716 and WJ-8718 are difficult to tell apart from the front if the name plate is missing. The AN/URR-74(V) and MFP version are easier to identify but you won't be able to tell a WJ-8716/MFP from a WJ-8718/MFP from the front if they are missing the name plate. The best way to identify these radios is to look at the back. |

The Backside ViewWJ-8716 - WJ-8718 - AN/URR-74(V) A quick look at the back is the easiest way to tell an WJ-8718 from a WJ-8716 or AN/URR-74(V). The WJ-8718 has barrier strips for audio connections. The WJ-8716 has BNC connectors. The AN/URR-74(V) has military connectors. |

This radio has an addition jack labeled J14, which is for the SMO - Spectrum Monitor Output, a 455kHz pre-IF filter 30 kHz wide output for connection to the WJ-9188-18 spectrum display unit that was designed to accompany these radios. (BNC above spare fuse). |

The Inside ViewWJ-8716 - WJ-8718 - AN/URR-74(V) The inside views don't reveal much difference to the untrained eye. The insides are essentially identical except for seeing the back of what you can already see from the outside. |
