THE CP-769/VRC-176 COUPLER IS A FULL AUTO-TUNER FOR THE TADIRAN VRC-176 & VRC-176A VEHICULAR RADIO.

AS FAR AS I KNOW, NO MANUALS ARE AVAILABLE FOR THE COUPLER.  IT DOES CONTAIN SOME SOPHISTICATED INNARDS.

IT IS THE ONLY MILITARY COUPLER I HAVE SEEN THAT ALSO HAS AN N-FEMALE CONNECTOR ON IT TO ALLOW YOU TO CONNECT A DIPOLE OR OTHER EXTERNAL ANTENNA, AND USE THE COUPLER AS AN AUTO-TUNER FOR IT.  RIGHT NOW, I HAVE MINE INSIDE THE SHACK FUNCTIONING AS AN AUTO-TUNER FOR THE VRC-176A ON MY OUTSIDE ANTENNAS.

IF YOU HAVE ONE OF THESE, HERE ARE THE DISASSEMBLY INSTRUCTIONS:

1.    LOOSEN 8 PHILLIPS CAPTIVE SCREWS ON BOTTOM OF UNIT

2.    VERY CAREFULLY, TAKE THE TOP OF JUST ENOUGH TO REACH YOUR HAND INSIDE

3.    WITH A SHORT STUBBY FLAT BLADE SCREWDRIVER, REMOVE THE CAPTIVE SCREW             

       HOLDING THE HIGH VOLTAGE WIRE ON THE BOTTOM UNIT.  DO NOT DISCONNECT THE

       HIGH-VOLTAGE WIRE FROM THE TOP OF THE UNIT

4.    LIFT THE TOP SECTION AWAY FROM THE BOTTOM

BELOW ARE SOME NEVER-BEFORE SEEN PHOTOS OF THE INSIDES OF THE UNIT.  CLICK ON ANY THUMBNAIL FOR A FULL-SIZED PICTURE:
