Long Range System
05/18/2010.Upgrade equipment long-range 869-915MHz LRS.
After some years and the teams have changed and improved. what began as a diversion is now a serious work.
I want to thank all users confidence over time.
Our teams in general have provided innumerable satisfactions to many people and have exceeded our sales expectations and scope, reaching 180km ULRs teams (Ultra Long Range) of dual use: military and civilian.
That is why we continue to work hard on improving the system of long-range 869-915MHz LRS as well as the OSD644DMDG.
I always liked to personally attend to my clients, but there comes a moment that is physically impossible, not enough time in the day for you all.
I have not write in RCGroups and I have very little of my free time. The design and customer service when in full production of LRS teams and development of some military equipment is not possible.
we are continually reshaping the structure of DMD and adapted to the new needs of our international clients with the aim of improving product quality and after sales service.
For some months you can contact directly with Bea, the sales manager for Skype in real time. He does not speak English, but can attend Posts smoothly.
Step directly to show you the new equipment and new presentation and packaging. Please view the photos.
Thank you very much

Hi, I am new in this forum, though very known in www.aeromodelismovirtual.com
I do not dominate well the English, but it will try to report of the new equipments of 868Mhz (Europe) and 902Mhz (usa) with which I fly.
It is of interest of long range FPV pilots.
Sending photos of the electronics equipments with which I have come fly to 12Km.
Juan Carlos (Murcia, Spain) has the record with RC equipments of 868Mhz of DMD in 16.5Km.
More info in Spanish (sorry) in http://www.aeromodelismovirtual.com/viewtopic.php?t=737
I advance characteristics of receiver...
RC Receiver for FPV or UAV
Incorporating the last technology of Radio Frequency and microcontrollers, the high quality of the electronic circuit, low weight and characteristics, they do of this receiver a small work of art, unthinkable one year ago.
Without adjustments parts, digital, synthesized, TDMA sincronous technology with 8 RF channels, hops & latency of 25ms, bi directional (receiver of radio control and data and send telemetry, coverage and data), identification IP in net, 5 % of occupation of channel, which allows 8 to 10 users simultaneously in the same zone.
This receiver is orientated to advanced systems of Radio Control, FPV and UAV of Long Range. Very high characteristics and modular.
With the equipments suitable transmitters and the necessary antennas be able to manage to control your model safely even 50Km!.
An important difference with regard to the recipients traditional RC is that can see the coverage of the radio link in real time in dBms and the % of data packets without mistake that receives in flight. This allows a very sure flight, can control at all time the quality of receiving and maneuver very much, a long before having problems of coverage.
These receivers are much less sensitive than them of 35Mhz, to the electromagnetic interferences caused by the regulator and the brusless motors.
Extendable with the CPU M128L for the control of navigation. It is prepared for OEM Original Equipment Manufacturer and to be programmable for advanced users who want to personalize your equipment.
Extendable with the option of integrated GPS that they allow a powerful equipment in very little space and with the optimized consumption.
Extendable with the module amplifier of 500mW bi directional PAISM05SH, for send telemetry from the airplane to land to long distances.
Two serial outputs with protocol RCBUS, for communications with other modules, advanced sensors or instrumentation.
12 channels for servos, extendable and controlables across the RCBUS, satisfy the most demanding user.
The details have looked after themselves very much, the outputs for servos, are protected of short circuits and voltage. A LC filter in outputs of servos, eliminate interferences of Radio Frequency.
Programmable BEC, for electric engine.
Programmable Fail Safe and configurable according to type of flight and conditions.
The Power entry of RF's module, takes a filter LC and a Linear regulator (LDO) of 3V.
A Watchdog of 0.1seg for falls of the system.
Independent exit for the control of an amplifier of power of optional RF.
MCX50 high quality antenna contectors.
The channels ch7, ch8 and ch9, they can be used as income for measurement of voltage (altimeter, sensor speed, temperature, etc.) the channels 10 and 11 can serve as income of batteries with included measurement, or outputs channels for servos.
Direct entry of two batteries Lipo 3S (11.1V), with automatic switchboard of batteries and DC/DC convertor integrated to optimize to the maximum the power drain for the servos and peripheral. The DC/DC in many cases saves battery of notable form.
Control and amplification of the tour of the servos, for the video camera.
The receivers of 11 series of 868/902Mhz are designed for the band ISM of 868-870Mhz of agreement to the European procedure ETSI EN 300 220 and availables for the band ISM 902-928Mhz in agreement with the procedure FCC of the USA.
