PowerMax Transmitter

The PowerMax is the ideal transmitter for the backpack mounting method using the TrackPack. Its exceptional power output makes it the right choice as a primary transmitter while the flat coin-shaped case keeps a very low profile on the back. Mounted up higher on the bird, the nine-inch long antenna does not extend past the tail. Furthermore, it's been designed to be easily left on at all times and easily turned on or off with the tap of a magnet for daily use.

The PowerMax incorporates a low-battery indicator, you might think of as a fuel guage, that uses both a timer and internal voltage sensor to warn you in advance when it's time to change the battery. Accumulated run-time is approximately 60 hours with another five days left to search after the double-beep.

Combining a Powermax as your primary transmitter, with a small Micro transmitter on the tail as the backup, provides you with two dorsal mounts that are up high, flat and aerodynamic, and out of the way. It takes a matter of seconds to Tap both transmitters to life with the Mag Switches and be ready to fly.

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

Available frequencies: 216, 217, 218, 219

HIGH POWER

The PowerMax has about double the range and distance of the RT+. Like any transmitter, the range varies with terrain, but tests have given distances of 10 to 80 miles in the open deserts of the western United States.

This makes it the right choice for your primary transmitter used to track down a bird in adverse situations. Our engineers also implemented a unique design into the circuit that maintains high power levels even as the battery drains, or as the temperature drops and the battery current follows suit. You can count on the PowerMax signal all the way through the life of the battery.

Signal range will depend on the height of the transmitter, the height of the receiver as well as the type of terrain and obstructions.

AERODYNAMIC SHAPE

Designed to hug close to the body, the PowerMax often dissapears below the large body contour feathers on the back of the bird after a vogorous rouse. Approach a bird that's been sitting comfortably on the block and it's likely you will not see it at all. The importance of a low profile design is serious at the high speeds experienced by most longwings, but just as important is for the bird moving through deep undergrowth or thick cover during a chase.

THE CONVENIENCE OF A MAGNETIC ON/OFF SWITCH

Over ten years ago, Marshall Radio pioneered the implementation of the Tap-On/Tap-Off magnetic switch. Magnetic switches at that time, where they existed, still required the transmitter to be removed and a large magnet held against the transmitter while stored away to keep it shut off. This saved the user having to untape and remove the battery every day just to turn the transmitter off each time, which was a step forward for the old brass battery contact designs back then.

The Tap-On was the logical next step forward in convenience, and together with the aluminum case designs and screw-on lids of today where the batteries are protected, it's now become a standard option on all Marshall transmitters. Many falconers just leave the transmitter mounted on their bird at all times, since there's no tape or rubber sleeve for a bored falcon to tear off, and then "tap" it on just before the flight. No fight getting the transmitter mounted, no conflicts or battles just before turning a bird loose. You only need to remove the transmitter once a month, or less, to change the battery.

LOW BATTERY SENSOR

After accumulating approximately 60 hours of actual run time, the normal single beep of the transmitter changes to a double beep every tenth pulse, letting you know that it's time to change the battery. Even though a transmitter switches to Low Battery Mode,  there's still five days of back-up time left to look for a lost bird. The transmitter runs at the same power levels but it simply warning you to change the battery.

You should get into the habit of changing the battery every time you hear the double-beep. If you were to fly your bird right before the double beep warning began, and the bird became lost, you would have about five days or so to search for it. If you continue using the transmitter into the Low Battery Mode, you will have an uncertain amount of time (much less) to look for it and will be at risk of not knowing, guessing at the amount of run-time left as with older designs still in use.

In addition to the 60 hour timer, the PowerMax monitors battery voltage, and will warn you with a double beep if you put in a weak battery.
