Mode A/C

The GTX 320A is a full featured, compact, panel mounted Class 1A transponder. The GTX 320A's solid state transmitter provides 200 watts nominal power output eliminating the need for a cavity tube that can degrade with time, fail, or require expensive replacement. 100% solid state also means no warm up time, reduced power consumption and heat for longer service life. Extensive utilization of surface mount technology provides shallow depth and light weight which simplifies installation in the tightest spaces. 14 or 28 volt operation is available without the requirement for external voltage converters or dropping resistors.

The GTX 320A fits into existing installations of selected Narco, King, and ATC transponders using optional adapters for simple, cost-effective upgrading. A single board design allows for ease of serviceability and simple, standard, four-knob tuning.

The GTX 320A can only be sold over the counter with a harness.
