Aviation headsets typically are not equipped with integral push-to-talk buttons. This is because most modern airplanes have push-to-talk buttons built in to the control yoke. Usually, older airplanes which date from "pre-headset era" do not have this convenience feature.
The solution is to add a PTT-400 portable, "strap on" push-to-talk button with plug in connections. These can be moved from one airplane to another, very rapidly, so they are ideal for renters.
Model PTT-400 is our response to repeated pleas from our customers, over the years, for a BETTER portable push-to-talk system. They have told us that they would prefer a PTT that was activated by pushing DOWN on the button, just like the ones built into the control yokes of today's newly manufactured airplanes. They also said that the "industry standard" strap-on PTT's are much too bulky, and protrude excessively to the side, making them clumsy to use, and sometimes interfering with use of the flight controls. Others complained that the standard PTT's need electrical modification to operate with their intercom systems.
We have taken these requests to heart, and designed an all new strap-on PTT system that addresses each of these highly valid pilot concerns. Our pilot/engineers started with a clean slate, to pen a revolutionary strap-on PTT design, housed in a cylindrical enclosure only about half the size as standard units. Its miniature, soft-touch, high-reliability pushbutton has been positioned so that the pilot can press DOWNWARD to invoke the radio transmit function, instead of the clumsy sideways motion required by past PTT designs. And the PTT-400 should not require electrical modification to work with any aircraft or portable intercom system.
Complete with standard aviation microphone plug and special slim-line jack, coiled cable and Velcro fastening straps, the PTT-400 is ready to be installed and removed in a hurry, virtually anywhere.
The Model PTT-2000 is a conveniently packaged, extremely reliable push-to-talk accessory, for use with the Model TR-2000 headset, or with other headsets or microphones.
The heart of the device is miniature (only 1/8 inch diameter), high reliability, red push-button. Rated by the manufacturer to provide 50,000 trouble free switching operations, it is unlikely to require replacement at an early date. Thousands of these remarkably reliable devices are in use today in our aircraft push-to-talk systems. Failures of the button have been extremely rare.
We have mounted the push-button in one end of a black, plastic cylinder (3/4 inch diameter X 1-1/2 inch length). This size and shape was selected so that the unit is comfortable to hold in the hand, and may be rested on the operating table, or even allowed to "drape over the shoulder" during listening periods. The five foot cable, which matches the cable on the TR-2000 headset, exits from the other end of the cylinder.
Contest operators have long lauded the footswitch as the very best way to implement the push-to-talk function, because it leaves the hands completely free for logging and tuning, increasing both speed and efficiency.
We have searched our suppliers for a high-reliability, microswitch based unit which is of appropriate size and has "just the right feel." The resulting FT-2000B footswitch is constructed on a steel base and hinged pedal assembly featuring a grooved plastic fascia, for excellent traction ability. It is equipped with a 10-foot cable to allow convenient routing to the transceiver. When ordering the Model FT-2000B along with our custom connector installation, the Model FT-2000B is wired to the mic. connector at no additional charge.
