When panel space is at a premium, the SL40 VHF comm transceiver combines a lot of capability in a surprisingly small package.
It’s an all-purpose, high-performance unit packed with innovative features not found on competitive units. In its space-having 1.3 x 6.25-inch design, the SL40 incorporates such pilot-friendly features as active and standby flip-flop frequency tuning, direct sunlight-readable alphanumeric display, a two-place intercom, and more.
The SL40's frequency-monitoring function gives you the ability to monitor ATIS or the 121.5 emergency frequency without leaving your assigned ATC channel. This allows you to listen to standby frequencies while giving priority to the active channel, meaning you'll never miss a transmission.
With 8 watts of transmit power and only 35-watt DC input, the TSO-certified SL40 is cool and efficient. No external fans or cooling equipment are required. And like the Garmin SL30, the SL40 will operate on 10 to 32-volt inputs without the need or expense of a separate voltage converter.
Maximum sophistication in minimum space: that’s the SL40.
