I would like to introduce you to a new radio modem that we developed for very long range datalinks!
Some of the key features of the RFD900 are as follows:
- Multi point and point to point link capability.
- Long range >40km depending on antennas and GCS setup.
- 2 x RP-SMA RF connectors, diversity switched.
- 1 Watt (+30dBm) transmit power.
- Transmit low pass filter.
- > 20dB Low noise amplifier.
- RX SAW filter.
- Passive front end band pass filter.
- Open source firmware / tools, field upgradeable, easy to configure.
- Small (30 x 57 x 13 mm), light weight (14.5g).
- Compatible with 3DR / Hope-RF radio modules.
- License free use in Australia, Canada, USA, NZ.
These modems are designed to support long range applications, while being easy to use and affordable.
These modems have been flying in various platforms and have demonstrated excellent performance in real applications.
RFD900 modems are now available at: http://store.rfdesign.com.au
Support within APM planner and the radio configurator from Michael Oborne is already available.
It works seamlessly with APM planner, all radio Mavlink parameters are available.
Update, December 2014: The RFD900+ with improved specifications is available now at:
good news, something is happening so. Nothing in http://rfdesign.com.au/products/ yet.
Just got my new 900x in the mail last week. I am hoping to connect a D4R-ii for rc control. Seppo assures me this is possible on the model which is why I get him to send me the new improved model. Not exactly sure how this is done yet or which pin my signal wire should connect to. So if anyone else has had success doing this.....? If not, then standby for further updates.
My current standard 2.4ghz system sends RSSI signal strength back to Taranis for audible feedback for FPV so I am hoping this will also be possible.
Any comments in this area will be great.
what is the difference with 900x?
Any update on RFD900x release date ? or test results ?
Seppo said 1-2 months in May...
I have a couple questions before ordering. Could please provide me an email? ( I just added you as a friend )
Just a random update ! - We have FREE DHL Shipping worldwide for this weekend, ending on Monday for all orders over $100 AUD. Just use the coupon code WOW to enable this :) Wishing all a nice weekend from all here. Seppo
I am working on an application for search and rescue where i need to relay telemetry from a low flying (search) vehicle to a high flying (relay) aircraft that re-transmits it to a ground station that is not in line of sight with the low flyer (search) vehicle. has anyone used these modems for that purpose? i had planned on using 3dr type transmitters but would rather get the range these seem to offer.
RFD has a relay system for their modem so as to use one as repeater
I got a couple of these RDF900+ radios and they communicate okay to each-other from my copter to mission planner, However, the range is the same as the 3DR radios.
Do I need to change some configuration to accomplish longer range?
Can they be used with 3DR? and if they do, what configuration should I use?
Thank you to all in advance for your help.
