Falconry Transmitters - Marshall Radio Telemetry

Transmitters for 2009

New for 2009 is the availability of transmitters on 433/434 MHz. The Scout is now available in 433/434 Turbo configuration which offers better range than the US version, and the new RT 433 will give you better range than any other falcon transmitter available in Europe.

The lightweight, high power Marshall Radio transmitters have evolved both inside and out for two decades now. You'll find Marshall transmitters to be carefully thought out and meticulously designed from every angle.

On the outside, the intricately machined, laser-engraved casings reflect our constant attention to detail and finish. While more costly and difficult to produce, machining cases from the toughest aircraft aluminum alloys gives the most precise way to achieve the tight tolerances we're after and provides the best protection for what's inside.

On the inside, all transmitter designs incorporate our new, extremely efficient and rock-solid circuitry. You can count on temperature stable operation, a high-shock design with an even more powerful yet stable signal in a transmitter that will last season after season. All other features matter very little without reliability first and foremost.

But what a list of unique features these reliable transmitters do have: the convenient and popular 'Tap-on/Tap-off' magnetic control switch, a real time low-battery indicator and fuel gauge, and extreme low temperature performance when battery voltage can drop down to a trickle that would kill other transmitters.

It's no longer necessary to put your bird at risk using the long 13-inch antennas of the past. Most Marshall transmitters, whether ordered in standard 216 or 218 MHz frequencies, are shipped with a short and safe 7 or 9-inch antenna.

The five designs detailed below each have a different intended use. The "Transmitters at a Glance" table found at the bottom of the page highlights the specifications and comparisons for each.

Drug-Free Installation of the TrackPack (New Version)

Scout and Scout TURBO
The Scout transmitter was designed for use with the larger hawks, such as Redtails, Goshawks and Harris' Hawks. But longwingers are also using it mounted on the TrackPack. It' key features are it's low price and long battery life:

- Runs forty days on a single battery (10 days for Turbo)

- Forty miles line-of-sight range

- weighs only 9 grams

- uses a short 7-inch antenna

- all at the lowest price possible

The new Turbo model offers 2-3x the range of the standard Scout while still offering a run time of 10 days.

Q & A l

RT Plus
The RT Plus is designed around the reliable 1/3N lithium battery which gives it it's unique shape and size. With its longer battery life and powerful signal, it was developed to be a primary leg mount for larger shortwings and longwings (18oz birds and up). The RT+ was the first of a new generation of transmitters with a short, safe, half-length antenna, yet still puts out more power than others still using long ones. It is also ideal as a secondary (backup) transmitter to the PowerMax tail mount. Features are now found in the RT+ never before available in a falconry transmitter (see link below).

Each unit is burned-in and Enviro-tested tested from +150F down to -40F prior to shipping. Thousands of this newest design are now in the field worldwide with enthusiastic and reliable results.

Q & A

PowerMax
Originally developed as the "ideal tail-mount," this transmitter has a flat, tail-hugging design with an antenna so short it doesn't extend beyond the deck feathers of the larger birds. Moreover, it's designed so it can be left on the bird and simply turned on or off with the tap of a magnet for daily use.

The new PowerMax is now lower in overall weight, puts out even more power yet runs even longer on the same 1632 lithium battery! It incorporates a new "fuel-gauge" type of low battery indicator that uses both a timer and internal voltage sensor. Accumulated run-time is now approximately 72 hours (instead of just 30) with another 4-5 days left to search after the double-beep.

It's particularly ideal for those considering the BackPack Harness. Birds as small as a Merlin have carried the PowerMax using the new TrackPack Mount!

Each unit is burned-in for five days and Enviro-tested tested from +150F down to -40F prior to shipping.

Q & A

RT Standard
Double the power of the PowerMax, the RT Standard transmitter is perfect as a backpack mounted transmitter for the long ranging falcon.

With its 10-day battery life and running in "Turbo-mode," the RT Standard is the transmitter of choice for falconers in the Gulf looking for the most range possible. The standard length antenna (13-inch) is best used on a backpack mount where it poses little risk. Can be ordered with a magnetic Tap on/Tap off Switch.

Now available with the "Bullet" Lid for better aerodynamics, and new "Rapid pulse" option, for pulses that are twice as fast for quick and easier tracking.

Q & A

Micro
This tiny transmitter is the "Ideal Tail Mount" for all sized birds. It weighs only 3.5 grams with the battery yet is a high-power, long range design putting 1/3 the weight on a single tail feather.

Unlike other transmitters using very small batteries, the new Micro doesn't fade out or die in low temperature situations.

It is perfect for small specialty birds: Merlins, sharp-shinned hawks and other extremely small raptors. You can order it with a 'fine' or a 'medium' gauge antenna, depending on intended use.

The Micro also contains the magnetic 'tap on/tap off' switch, a half-length 7-inch antenna with improved power and efficiency over the old Micro. Each unit is burned in for five days and Enviro-tested tested from +150F down to -40F prior to shipping.

Q & A l

"I wanted to let you know that I used my RT+, can't remember, as a hack transmitter this summer for my female goshawk that I pulled from a nest here in NM. I imprinted her and when she branched I put her in a cottonwood on my property. She was out every day for 27 days, spending her nights indoors. The transmitter functioned perfectly on one battery, she always took very long baths in the afternoons - a habit which wreaked havoc with two of my other non-Marshall transmitters. Anyway, just wanted to thank you for a superior product."

WARRANTY

Marshall Radio Telemetry warrants its transmitters to be free of defects of workmanship and materials for one (1) to three (3) years, as shown above, from the date of purchase. Our Warranty is to the original owner. If your Marshall transmitter is defective, return it to Marshall Radio or one of its authorized Distributors and we will repair or replace it free of charge. However, we will not be responsible for damage from misuse or for normal wear incurred from regular use. Under no circumstances will Marshall Radio be responsible for damages or loss beyond the value of the transmiiter itself, including the loss of a bird or lost time. The complete unit must be returned, transportation prepaid, to an authorized Marshall Radio Service Center.

WARNING: It is in the nature of any radio frequency transmission device, including transmitters used in falconry, that signal propagation (range of signal transmission) can be greatly reduced if the transmitter or antenna is touching or lying on the ground. Marshall Radio, and all of our retail outlets around the world, strongly recommend that you use either a Backpack, tail mount, or neck mount (#16 rubber band only) for one transmitter, and use a second transmitter mounted on an alternate location such as the neck, tail, leg or backpack. TWO TRANSMITTERS ARE BEST FOR ALL OF THE LARGE TIERCELS AND FALCONS. If you use only one transmitter, please consider mounting it only on the neck, back (via backpack), or tail, where the probability for good signal propagation is greatest when your hawk is on or near the ground.
