Uniden PC787

The PC787 is the latest CB radio from Uniden.  It replaces the PC78 series radios and has a very similar look.  Right away, though, you will notice the larger meters and fewer knobs. The PC787 also uses a 6 pin microphone, unlike its predecessors.

The extra-large S/RF/SWR meter lets you check you levels with a glance.  The PC787 has all the features important to you: integrated SWR meter, mic and RF gain, weather alert, noise blanker, automatic noise limiter, instant channel 9/19, and more.

controls and functions

Uniden PC787

1. Multifunction meter. When receiving, the meter shows the received signal strength. Use CAL and SWR to tune an antenna for best performance.

2. S/RF/CAL/SWR switch: Selects S/RF, CAL, and SWR to be measured through the multifunction meter.

3. CB/WX/PA switch: Selects CB (Citizens Band) or WX (Weather) modes, or activates the PA (Public Address) feature.

Do not use the PA function unless an external speaker is connected.

4. NB+ANL/ANL/OFFswitch: Activates the Noise Blanker (NB) and Automatic Noise Limiter (ANL) features. NB reduces external noise and ANL reduces background noise from the car engine and other sources. OFF turns off both the NB and ANL features.

5. 9/19/NORM switch: Move the switch to select emergency

channel 9, channel 19, or standard CB channels.

All channels except Channel 9 may be used for normal communication. The FCC reserves Channel 9 for emergencies involving the immediate safety of individuals or protection of property. Use Channel 9 to render assistance to a motorist.

6. HIGH/MED/LOWswitch: Adjust LCD backlight brightness.

7. RX/TXLED: Indicates whether the radio is transmitting (red) or receiving (yellow-green).

17. Antenna socket: Connects antenna to the unit.

18. PA SP: Connects optional external 8-ohm, 4-watt speaker for use as a public address system.

To prevent acoustic feedback, separate the microphone from the speaker when operating the PA at high output levels.

When the external speaker is plugged in, the internal speaker is off.
