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:
Does anyone know of a store that has that connector in stock everywhere I have looked it is backordered or sold out, also wouldn't you think they would have sent it with the 900u considereing its the only way to upgrade firmware.
Welp... looks like you have to buy one of these...
Then you have to make this:
As far as the SIK radio firmware, you can either use mission planner or use RFD Tools
Does anyone know where to find the RFD900u to 8 way socket cable anywhere before I try and make my own, how did you guys all get SIK radio firmware added to your 900u?
well that counts me out then 900x i not going to up date all 7 900+ i have bummer

Short answer , no.
The hardware is capable but old modems would need mods to keep up with x versions and they are hard to change. There is an ever increasing list of features being added to the x, and the 900+ will not be able to support these. We don't anticipate that they will be compatible unless someone in the SiK development group wants to tackle 900+ upgrade issues.

I'm not sure exactly what your setup is, can you explain?
Are you using the ezhf somehow with the rfd900 or just 2 systems side by side?
if so can you turn off uhf system, does rfd900 work correctly?
If this fixes the problem then interference is the issue, if not then we need to look at other possible issues.
900x doesnt appear be compatible with 900+
Sorry could not read through the entire thread. I am using RFD900 with EZUHF system. But getting just over few hundred feet range performance which is frustrating. Did anyone have similar problem? What could be the solution? Some sort of filter on UHF system can help?
Thanks for help.
Is the 900x capable of communicating with 900+'s and 3dr modems?
