10.7 MHZ IF Output

The buffered 10.7 MHz IF Output is available at the output (pin 5) of IC5. References throughout the Internet to Q85 are only related to the PCR1000, a different Icom product. IC5 is located on the bottom of the PCB. When looking at the bottom of the PCB, with antenna terminal to the top and right, IC5 is located immediately below and to the left of the center-most mounting screw, within the RF shielding box. Pin 5 is diagonal from the pin with the dot above it (Pin 1), and is the closest pin to the mounting screw.

This output will carry either 4.1V or 1.7V depending on filter selection elsewhere in the signal path. Depending on your use, a small capacitor such as a .22uf bipolar should be used inline with this signal to protect external hardware from this voltage.

All above information can be readily explored in the ICOM IC-PCR100 Service Manual #A-5548MI-S(1998) and associated schematics and board layout.

 === 10.7 MHZ IF Output ===
-The buffered 10.7 MHz IF Output is available at the emmiter of transistor of Q85.  Q85 is located close to the edge of the large board, near J1. If you place the radio with the antenna connection to the left, Q85 is the first transisor to the right of the smaller IF filter at the top lefhand corner of the RF board. This is directly above the metal can for one of the LO's.  The emmitter is the upper left terminal (if the radio is oriented as described above). There will be a DC level at this point, so will want a coupling capacitor. (Thanks to gr8amp in the forums)
