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:
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:
I am currently using RFD900+ (and RFD800+) with RFD Multipoint SiK on plenty of modules and I have two questions:
A) The datasheet specifies that NETID max val = 499. However if we want to maintain a fleet with more than 500 pairs and would like to have unique IDs I would like to set values greater than 500. At first sight, this seems to work. Is there any risk associated with? Or does somebody know where the limit comes from? I already checked with the manufacturer concluding that if there is a limit, it's due to the firmware.
B) On some of my modules I cannot set TXPOWER to 27 (500mW), but it always sets it to 26 instead if I check afterwards. It even seems that all odd numbers are "blocked" and are always floored to the next even number. Does somebody know about this behavior? Or know how to mitigate or get rid of it?
Thank you in advance for any reply.
