This is the front panel of a WJ-8716 receiver. These receivers are relatively common although internal options vary and some of the options are rare. They saw a lot of action on Navy ships with the /NAV option package.

MFP - Microprocessor Front Panel version

The basic receiver is digitally controlled but has no microprocessor. Standard configuration tuned DC to 30 MHz. Performance in the LF range is very good. IF bandwidths of 0.3, 1, 3.2, 8 and 16 kHz are standard. Standard receiving modes are AM, FM, CW, USB and LSB. ISB is listed as an option but the only radios I have seen for sale without ISB were stripped their SSB cards. A variety of options like a tracking preselector, RS-232 or GPIB remote control and 1 Hz tuning resolution were available. These radios were expensive, especially when you add certain options.

The inside of this WJ-8716 reveals two nice options. It has the PRE - preselector (larger silver box in the upper bay), the 488-1 - GPIB remote controller (middle and lower cards in the second bay from the bottom). These options seem to be more common on the WJ-8716 than any other version.

The back of a different WJ-8716. This unit has no options. The IF output jack is a standard post filter 455 kHz output. Notice the BNC connectors for audio.
