Transmisor Marshall Rt Plus
  
El RT está diseñado alrededor de una batería 1/3N de litio, la cual le da esta forma y tamaño únicos. Con su batería de mayor duración y señal más potente, fue desarrollado para ser la principal opción en pata de grandes falcónidas y accipítridas ( aves de más de 500 grs.). El RT+ fue el primero de una nueva generación de emisores con una antena de longitud media, corta y segura, sin perder potencia. Es también ideal como emisor adicional con un Power Max colocado en la cola.
Antes del envío, cada unidad trabaja durante 5 días y se prueba en exteriores a temperaturas entre –26 y 65ºF.
NOTA: La nueva 2004 RT+ mostrada a la izquierda estará disponible para pedidos hacia el 25 de junio. Para más detalles sobre este emisor, pincha en el enlace posterior “artículos/uso deseado”.
RELIABLE
“All other features come second to reliability”
For the 2004 RT+, it’s at the top of our list. Every aspect of this new circuit had reliability at its core. Everything from the 54 components selected and used in this stable new circuit (some parts have an average rated life of 300 years!), to the processes used in the manufacture (surface mount technology) to the mechanical design makes it the most bombproof design possible.
HIGH SHOCK
The crystal-based oscillators of the past have always been vulnerable to failure through crystal breakage when used as a leg mount on hard-hitting birds. Using new generation surface-mounted high-shock crystals, the risk of having your transmitter fail from a fractured crystal has been reduced to near zero.
FREQUENCY STABILITY
What does this mean to you? Tune in once and the signal is always there, same pitch, same sound. The 2004 transmitter circuit automatically adjusts to changes in its environment. In addition, temperature and voltage compensation handled by the circuit guarantee you always hear the same tone in extreme environmental changes.
SHORT ANTENNA
The general rule in producing a powerful radio transmitter antennas has always been: do not cut it shorter than ¼ wave length (which is 13 inches at 216 MHz), or you’ll lose a lot of the radiated power output. But with the 2004 Marshall transmitters, we’ve found a way to overcome this barrier and increase the output power while keeping our shorter, much safer antenna.
MAGNETIC SWITCH
Now standard on the RT and the Micro, optional on the BP. With the Magnetic On/Off switch, batteries can be left inside the transmitters, until they need to be changed. To turn it on, you simply hold the magnet to the lid or body of the transmitter until you hear three rapid beeps, which tells you the transmitter is on and running. You do the same thing again to turn it back off.
This means transmitter can be left on the bird, such as a bird touchy to tail mounts, and then be turned on again just prior to the flight with the tap of the magnet. Tap-on just before flight; tap-off after picking bird up again. This new convenience does not add any risk to the reliability of the design, as it’s fault positive, meaning, if it should fail for any reason, the transmitter is left on. Also, if the magnet is lost, the transmitter can still be turned on and off manually as before.
BUILT IN BATTERY TESTER
No more having to ‘test batteries’ with a battery-tester before each flight to see if they are nearing the end of their useful life. The transmitter does all this for you: you get a double-beep on every fifth pulse indicating it’s time to change. And, when you first hear the low battery warning, you still have a 3-4 day reserve to look for a lost hawk.
NEW LEVEL OF EFFICIENCY
We´ve found a way to again improve on the efficiency of the circuit, giving the most power output while barely sipping power from the battery thus extending it’s life as long as possible. Using the latest generation of field effect transistors and dynamic resonance circuitry, this new design pumps more energy into the antenna without wasting as much power through internal resistance.
What this actually means is: it lasts longer.
CONSISTENT POWER OUTPUT
Also, through greater efficiency in the circuit (and some black magic inside), the power output you hear will now be more consistent as the battery drains. This is not the case with the older designs where weak batteries or very cold temperatures mean a correspondingly weak signal or failure.
Intended Use:
AS A TAIL-MOUNT
Using the French-clip design, the RT+ can be mounted to one of the deck feathers of a large falcon or hawk. The spring can easily be removed in the field to make an emergency switch to a leg-mount.
NEW CASE DESIGN
Still machined from the strongest aircraft alloy available (7075), these carefully crafted cases protect the internal circuitry while giving protection to the batteries as well. For the RT, the overall appearance and weight is similar. But, there’s a new flat ‘fin’ portion at the bottom which now gives better leverage and grip when screwing down cap.
IDEAL BACK UP TRANSMITTER ON THE LEG
This transmitter is best used as a longer-life tarsus mounted transmitter in combination with a PowerMax or Micro on the tail or BackPack Harness. The leg mount shown here is the most common use for the RT+ due to its shape and size.
DOUBLED UP ON A GYR
The RT has also been successfully used side by side as a redundant tail mount system on larger birds that can carry the weight, as shown here.
