Garmin is replacing its decade-old line of nav/com radios with more powerful models that add features and comply with coming European regulations that require 8.33 kHz frequency spacing.
The new GTR (a transceiver) and GNC (a nav/com) replace the popular SL40 and SL30 models—but they’re not slide-in replacements since the new models are slightly taller.
“These products demonstrate Garmin’s commitment to aviators worldwide by providing the solutions they need to meet the latest regulatory requirements in their regions,” said Carl Wolf, Garmin’s vice president for aviation sales and marketing.
The new radios are FAA approved and come with 10 or 16 watts of transmitting power, up from 8 watts in the SL series. They also have a built-in two-place intercom and the ability to listen to a standby frequency, store up to 20 frequencies in memory, and look up frequencies using airport or VOR codes.
Prices for the units, which will be available in February, range from $1,995 for a 10-watt GTR to $5,495 for a 16-watt GNC with 8.33 kHz spacing.
Garmin officials declined to say how long they will continue offering the SL30 and SL40 models.

FAA Systems and Airspace
NextGen was intended to improve access and efficiency in the nation’s busiest airspace. But two new RNAV terminal routes proposed west of Washington, D.C.’s, Class B airspace do just the opposite.
The FAA has proposed a reduced Class D airspace area at Alaska’s Bryant Army Airfield after concerns from the public, saying additional information is needed.
In 10 years, the FAA has created more than 3,000 approaches utilizing Wide Area Augmentation System (WAAS) GPS technology, expanding access to small airports.
