Displays

The 7 Segment LED channel display already mentioned (00 to 99).

2.A 5 segment LED light array for AF, that aids in setting micro- phone gains and monitoring receiver microphone and line level outputs. Light numbers 4 and 5 have a Peak Hold feature.

3.A 5 segment LED light array for RF, that aids in checking the transmitter and monitoring for the possibility of initial interfer- ence.

4.A 2 segment LED array that indicates diversity action and antenna configuration.

Audio Output

An XLR type connector is located on the rear panel that provides either line level audio or microphone level audio output, which is controlled by a slide type switch also located on the rear pane. The output level is adjustable with a screwdriver accessible potentiometer located on the rear panel.

Power

The USR-100 will operate from the supplied AC adapter or any nominal 12-15 volt AC/DC 600 mA supply.

Audio

The USR-100 audio circuitry is designed to complement the trans- mitter audio. A compandor circuit is utilized to enhance the dynamic range. A slow turn-on circuit prevents the audio output stage from passing noise spikes present during receiver power up conditions.
