  • GTR 200 provides a 150 Ω AC input impedance and supplies the microphone with an 11 V bias through 470 Ω +/- 5 percent
  • Two inputs, standard carbon or dynamic mic with integrated preamp
  • Less than 25 percent distortion when the transmitter is at 85 percent
  • Stuck mic time-out, 35 seconds time-out, reverts to receive
  • AM double sided emission designator, 6K00A3E (118-136.975 MHz)
  • Active and standby flip-flop frequencies with location and type identifiers
  • One-touch 121.5 emergency channel tuning
  • Comm frequency monitor function (listens to standby while monitoring the active)
  • 3D Audio separates active and standby frequencies as well as the intercom in headset
  • Auto-squelch listens to the natural noise in the cockpit and automatically adjusts the squelch level
  • Automatic display of the airport identifier and type after tuning a frequency from the user defined presets or a frequency list transferred from a compatible portable GPS or G3X system
  • 10 W transmit power and 25 kHz spacing
  • Large, sunlight readable display
  • Total product footprint is 1.35” tall by 6.25” wide. Has only a 9.4” behind-the-panel depth including connectors (8” without connectors).
  • Only 1.34 lbs. (1.91 lbs. with rack and connectors)
  • Optionally installed switches allow remote control of frequency flip-flop and/or pilot/co-pilot squelch
