Introduction The Tramp HV is a tiny, high power 5.8GHz Audio/Video transmitter designed for FPV use, but with a focus on the Drone Racing market. Equipped with a dual user-interface, one a traditional button/LED, and another using near-field communications (Touch’N’Race) to configure the transmitter using a contact-free wand.
Best Practices Connectors and Cables The trend to miniaturize FPV video transmitters, and dramatically decrease weight requires the use of smaller, and therefore more fragile connectors than used on ‘legacy’ transmitters. When mounting the transmitter, ensure that these connectors (especially the tiny U.FL antenna connector) is not being pulled, or can be pulled in a crash. If the U.FL to Bulkhead SMA cable gets damaged it may be replaced easily.
thin ‘carpet tape’ to ensure that the close proximity of the frame doesn’t affect the TNR range. NOTE: For the tramp version used for events in July/Aug 2016, please connect the TNR board to the Tramp and power it up at least once before arriving at race events. The first customer release will not require this. Antenna Compatibility The pigtail supplied with the Tramp sports a standard SMA connector, NOT a RP-SMA which is used by some other manufacturers.
Setting Channel/Band/Power using the button First, a disclaimer, this transmitter was not designed to use the button as the primary userinterface. The TNR Wand is by far the easiest way to configure the transmitter, and provides both feedback of which channel a transmitter is on before it is powered up, and define the current band/ channel, and power level. Three ‘Menu Options’ are available using the button and LED, shown in the flowchart below.

Bands, Channels, and Frequencies Depending upon the Tramp variant purchased, the power output level, and available transmit frequencies can vary. It is highly recommended to understand the rules and regulations in your country before using the Tramp. Transmitting outside a legal band is something frowned upon by the authorities, and may result in a fine, or confiscation of equipment. As a rule of thumb, the following charts should help understand which frequencies are legal in each of our main markets.

Troubleshooting On startup, 2x blinks TNR Device detected, but data appears corrupted. On startup, 3x blinks No TNR Device connected/detected (informational code, Tramp will run happily without this connected) On startup, 10x blinks TNR Device detected, but cannot write to it. LED does not light at power-up This is almost definitely due to a supply voltage problem, check all cabling to the Tramp.
Revision History V1.21 –– Initial revision used at the Swiss, and NYC Nationals V1.22 –– Change in behavior when detecting an uninitialized TNR board at boot. Race mode request using the wand will always be respected on first power-up at an event. –– Change in button behaviour, a device in Race Mode, wanded and ready to fly, will ignore the button, even for emergency unlock requests. This only affects cases where the Tramp was installed with the button pressed before powerup, and for 30s after powerup.
