Introduction

Welcome ...

Welcome to a new era of aviation communication and navigation. Once again, Garmin AT, Inc. has set new standards in features and ease of use for the general aviation public. The SL30 is a VHF Navigation/Communications Transceiver for use by the aviation pilot. The SL30 is packaged in a slim form factor that helps you get the most out of limited panel real estate without limiting features and performance. The SL30 is unequaled in providing the features, level of performance, and reliability that aviation users expect. The high performance Digital Signal Processing (DSP) filter design of the SL30 allows it to track weaker VOR signals with more accuracy than conventional analog receivers. Add additional features like Morse code Station Identification and Multiple VOR tracking and you begin to understand the Advantages of DSP in a VOR Navigation System. The use of DSP technology in the SL30 provides a state-of-the -art device, which packs more performance in less space for less cost. You can be confident in knowing that you are the owner of the state-of-the-art in aviation communication and navigation. Our products are built to last and to allow the flexibility to meet your needs as they change in the future.

Getting Started

Combining a powerful 760 channel VHF communications transceiver with 200 channel VOR, Localizer and Glideslope receivers, the SL30 provides a full-functioned navigation and communications solution in a small footprint at a very affordable price. Besides traditional Nav/Com features, the SL30 also incorporates workload-reducing functions such as automatic decoding of the Morse code station identifier for VOR/LOC, most-used frequency storage in memory, built-in course deviation indicator, and more.

The SL30, the smallest Nav/Com on the market, is loaded with features and functionality. The only Nav/Com with the ability to monitor the standby Com and Nav frequencies, the SL30 VHF Nav receiver operates from 108 MHz to 117.95 MHz decoding both the VHF Omni Range and Localizer navigation signals. The built in Glideslope receiver will automatically tune the corresponding glideslope paired frequencies (328 MHz to 335 MHz) when the localizer is tuned. The SL30 includes the powerful yet efficient 8 watt com transmitter used in the other SL Slimline and GX avionics.

Display

The SL30 Nav/Com uses a single line by 32-character 5x7 dot matrix alphanumeric display. A photocell is located in the top left corner of the front panel display. The photocell automatically controls the light intensity of the display LEDs from low brightness at night to high brightness during daylight operation. The lens is polarized to reduce reflections. Using polarized sunglasses may make it difficult to view the display.

TX

A transmit (TX) indicator located above the Flip/Flop button lights when the Com radio is transmitting.

Controls

Power On/Off - Volume - Squelch

The knob on the left side of the SL30 controls power on/off, volume, and squelch test. Rotate the knob clockwise (CW) past the detent to turn the power on. Continuing to rotate the knob to the right increases speaker and headphone amplifier volume level. Rotate the knob to the left to reduce the volume level. Pull the knob out to disable automatic squelch. The SL30 may be configured to have the volume knob control Nav and intercom volume, as well as Com volume.
