Field Marshall Digital Tracking Receiver (UHF)

thumb_Field-Marshall_logo

Building on the success of the original Field Marshall UHF design, the next generation still retains the features customers loved on the first UHF receiver such as the tiny yagi antenna, compact and portable form factor, and superior range over VHF based receivers. But the 2014 model offers several additional improvements such as temperature compensation (no need to retune when chasing a far off signal as the temperature changes), improved pin point accuracy for searches up to the last few feet, and even better sound quality. It also has a new distinctive color scheme, which identifies our UHF equipment line going forward.

The Field Marshall UHF provides falconers in the UK and EU the best performance of any tracking receiver availalbe today.

Each receiver still comes with a field holster, but it's very small shape and size makes it a "pocket receiver" capable of being slipped into your Hawking bag or section of your Pineo Hawking Vest.

Features

PICK UP ANY FREQUENCY YOU WANT (FM2000 model exclusive)
Since this receiver doesn't rely on crystals to determine the frequencies it can cover, we're were able to give it much more capacity. An all-digital circuit allows the same receiver to pick up any frequency in the 433 through 434 MHz bands allowing every frequency you could possibly want or just the ones you're interested in.

EASY TUNING
A broadened, smoothed tuning mechanism means that tuning into the signal is a pleasure and much faster than before.

Tuning with the new tune knob is broad and is protected from accidental contact so it's not easily bumped off your tune setting when getting in and out of the vehicle.

Higher Sensitivity: With the new digital receiver board inside the Field Marshall, we've improved sensitivity by another 3dB, which translates into a significant increase in reception distance for the same transmitter.

The actual sound of the receiver has been improved through the elimination of harsh harmonics and distortion, making it easier to track weak signals and far more pleasant to listen to.

Three red LEDs now illuminate the entire control panel for better clarity in the dark without compromising your night vision.

QUICK-RELEASE HANDLE
As great as it is to have a handle on long walks or when holding the receiver out the window, there's times when it's better without it. Greater portability and reduced size is achieved without the handle on a third axis.

So, how to have it both ways?

Answer: The new Quick-release handle. Now, you can choose when to use it and when to put it away in another pocket. Even though it's tight and secure with its bracket mount, it takes only seconds to remove it using the thumb wheel screw-on design. Those who've now used it, love it.

RECONFIGURABLE DESIGN
Not only can the handle be quickly removed, but it also attaches directly to the antenna with the same bracket assembly. This gives you three different ways to configure your receiver: 1) everything together in one single piece, or 2) hold the smooth and smaller case in your hand without the handle, or 3) wear the box safely around your neck and connect the handle directly to the antenna to hold outside the window in the rain.

SPEAKERS ON TOP AND BOTTOM
Hold the receiver down waist high and you have two speakers facing up at you. Hold it up high for better reception and you still have a speaker facing down at you. By incorporating speakers top and bottom, the sound on the Digital Field Marshall has been improved from any direction you may be holding it.

And yet it's also quiet where it needs to be: A new narrow-band filtering system is employed rejects noise better without reducing your signal, so you hear the signal more clearly with less distracting background noise, even for the weakest signals.

More importantly, it has improved the sound's omni-directionality which means the volume doesn't change as you rotate the receiver, a definite problem in other receivers that leads to erroneous perception of the signal strength in certain directions.

Nearby transmitters on other channels sometimes cause interference to your reception, but this receiver has special circuits to minimize the effect.

The improved rejection of noise near power lines means you can hear weak signals better and increase your range.

Better Range Estimation: The range settings (Medium and Near) have been adjusted so that you know it's time to start walking. You can therefore switch between these in most situations to get a better idea of how far from you the bird or dog really is.

HIGH-END PACKAGING AND ERGONOMICS
Electronics are housed in a robust case machined from a solid block of aircraft aluminum.

Purposely made for outdoor use, this tracking receiver is designed to give you more years of trouble free operation through the widest range of temperatures, travel and weather than any other. Sealed connectors, mylar speakers, solid block machined casing with overlapping seams all make this receiver the most durable design on the market.

NARROWER CASE
In addition to all the performance improvements made to this receiver, Marshall Radio engineers redesigned and shrunk main circuit board to about 20% less total area, with everything fitting inside the case much more efficiently, leaving no wasted space. We then asked our external design team to "vacuum pack" the new machined aluminum unibody case down to the absolute minimums required. No wasted airspace on the inside, no needless bulk on the outside.

With the handle removed, the slimmed down design fits even better in your hand. Designing the outer case to be hand-held required we made additional changes, like a larger radius on all corners, and counter-sinking the earphone and power jacks to make them flush with the surface of the case, all of which just makes it feel smooth and solid, more like an over-sized iPod in your hand.

The case is now even more stout and rugged than even the previous generation Marshall receivers. It's also designed to use six AAA batteries, cheaper to replace, and easier to change.

SMALLER, EVEN MORE RUGGED COLLAPSIBLE YAGI ANTENNA
We kept the same, field proven, collapsible, three-element directional antenna design for maximum directionality. It's a full gain yagi when deployed, but now collapses to an even smaller size. We reduced the size of the brackets, the sliding booms and eliminated the need for cables, cable savers and big springs. Also, rugged solid rods are used for the elements instead of hollow tubes.

Improving the shielding on the case also means an improvement in how the antenna works for you. It's simple now to track a transmitter lost in the grass with the same pin-point directionality you get at a distance. The full-size three element yagi gives the best range and directionality of any antenna, and reduces the "back lobe" which sometimes fools people into tracking 180 degrees backward, in the wrong direction.

LIGHT WEIGHT
Using newest generation electronic components and creative packaging allows us to fit a lot into a small space.

And, our committment to using aluminum alloys which have the maximum strength to weight ratios makes this receiver as light and strong as technically possible.

EASY TO TAKE WITH YOU IN THE FIELD
A key mechanical design breakthrough of all Marshall receivers is the collapsible yagi antenna. The full-sized three element antenna (shown above right) can be reduced in size by half when fully closed.

When collapsed down into its stowaway position, and put into its hoslter (included with every new receiver), the new Field Marshall makes a small and compact piece of equipment to take with you into the field.

Q&A

Can I pick up non-Marshall transmitters with this receiver?

Yes, if they are transmitting within the range which the receiver covers, and the new Digital Field Marshall receievers are designed to cover the existing frequencies commonly used throughout Europe. Most existing 433 and 434 MHz transmitters can be tracked on the Marshall radio receiver. The 100 channel receiver covers 434.000 to 434.099, so that any transmitter with a number in that range could be heard.

If you have transmitter outside this section of 434 be sure to order either the 500 (434.000 to 434.499)  or the 2000 (433.000 to 434.999). And, if you have 433 transmitters, order the 433 500 channel model. Be sure to double check that your existing transmitters are within the exact frequency coverage when ordering on-line, or verify verbally by phone.

What do I do if I break one of the antenna elements?

Each antenna element threads on to the spring-loaded connector at the center. A new element can be sent to you for an easy replacement. You only need to contact Stephen Lea, who manages our UK Marshall-Direct Customer Support office using "Stephen@marshallradio.com."

What if I need extra small parts, like if lost a Thumbscrew to the battery lid, or the lid itself?

A small "Extra Parts Kit" is included with each receiver, containing these items. Extas can be requested from Marshall-Direct.

What is the thinking behind the Quick-Release yagi and handle?

For many years, the receiver handle has been permanently fixed tothe receiver case. Customers have increasingly asked for a removable handle so that in certain situations, the receiver did not appear to be a weapon to the non-experienced observer. With the redesign of the new Digital Field Marshall the case was made 30% narrower which made holding it in the hand without the handle even more practical. Accordingly, the "Quick-release" handle was designed to give customers a choice.

The Quick-release mechanism also matches the attachment on the bottom of the yagi antenna, so that the two parts can be easily re-combined into a hand-held yagi operated separately, using a 5 foot cable, if desired.

How about rain and snow? What happens if I get this new receiver wet?

The Field Marshall has been designed for heavy outdoor use, and this means we know there will be times caught out in wet weather. It can take a certain degree of moisture. If you are out in precipitation, it can be used in the normal orientation, taking care not to needlessly expose the Control Panel directly to excessive water accumulation by pointing the receiver down.

This receiver and its speakers can take exposure to moisture that would ruin other models and void their warranties. As soon as you’ve finished tracking your birds in heavy rain or snow you should turn it off, and simply remove the batteries. Then,  place the receiver in a warm dry place with the handle on, so that the front panel is on the surface and the front of the yagi is upright. The receiver is designed to channel any water away from the circuit board if left in this position. After leaving in a warm dry place over night in this position the receiver is ready to go.

If customers follow these instructions then they should have no issues. But if the receiver is in heavy rain or snow and then left in bag for a few days, the circuit board and front control panel can get  corroded. So whilst the receiver is designed for use outdoors and in all weather, but it must be dried out as soon as possible if wet and the batteries must be removed as soon as the customer has finished tracking so the unit can beimmediately allowed to dry.

What is the best lubricant for the sliding boom of the yagi antenna?

When used sparingly, any low viscosity lubricant will work. Common spray lubricants such as WD-40, Tri-Flow, etc. can be used. We recommend first cleaning the sliding boom (with a damp cloth, or a cloth soaked in rubbing alcohol). Then apply the lubricant to a cloth or paper towel and  wipe it onto the square “slide” of the antenna.  Open and close the antenna a few times, then wipe off any excess to avoid the attraction of dirt or debris. Do not use any heavy oils or grease.

What are the advantages of the different frequency bands?

This is a topic of much debate among telemetry users. First and foremost, frequency bands should be selected based on what frequencies are legal for use in your country. In some countries, multiple bands are available for radio telemetry use. In those areas, the user may select the band that offers the best combination of performance, antenna size, and range. Generally speaking, a lower frequency offers better signal propagation (longer range) and better diffraction over hills and obstacles, while higher frequencies allow for smaller aerials and antennas (nice when hiking through dense woods or operating from within a vehicle). The small differences in frequency within a band have little effect on performance,  i.e. 216.005 will perform the same as 216.795.  In some areas, one band may be contain more background noise than another band. Bands with the least background noise provide the best range.

What batteries are best to use?

For general use,  Alkaline AAA batteries are the most cost effective and provide good battery life. They are commonly available as well. Lithium AAA batteries offer the best performance in cold weather, are the lightest, and last the longest (but cost significantly more). Rechargeable batteries (such as NiCad or NiMH) should not be used as they do not provide sufficient and consistent voltage to operate the receiver effectively.

Always use name brand batteries (like Energizer or Duracell) with a comprehensive warranty, in case there is ever an accident with the actual batteries inside your receiver.

Can the frequency range of my Field Marshall be reprogrammed be changed?

A lower capacity Field Marshall can be upgraded to include more channels (for example a Field Marshall 100 can be upgraded to a 800, 1000, or 4000), but the band must reamain the same (i.e. a 216 MHz cannot be changed to a 173 MHz).

Can I hook it up to an cartop (Omni) antenna?

Yes, the Field Marshall easily excepts input from an external antenna, simply remove the coaxial cable from the receiver body, and plug in the coaxial cable from your external antenna. The Field Marshall uses a ‘SMB’ connector, most omni antennas use the larger ‘BNC’ connector. A simple adapter (included with the purchase of an omni from Marshall Radio) can be used to connect other manufacturers antennas to your Marshall Receiver.

I don't see any place on the website to order replacement parts.

A small packet of common parts, like an axtra cable, thumbscrews, etc are provided with your new receiver. Also, replacement parts are just a phone call away, and we'll send out what you need.

How do you handle repairs when the receiver is out of Warranty?

If you receiver requires repair outside of the warranty period, it can be returned to Marshall Radio (or through your local distributor) for repairs at reasonable cost to you. You will be notified with the results of our testing and evaluation as to your options and their costs.
