Just been looking at the OpenLRS kit...    can run in UK legal 459mhz freq and at max 100mw ... range 3/5km stock.. further with better antennas and boosters if you need it..

Looks very good...  and very cheap compared to other systems.. seems great for Multis..  It';s not as powerful as Dragonlink and EZUHZ or RMILEC, but certainly should deliver range well beyond what 2.4 can
.. which would be fine for a multi

The Tx module fits the 9x and also the new 9XR which can be bought without modules... if you need a new TX this makes a very good UHF long range system with failsafe and telemetry capability.. RX and TX Modules with 9XR = $99


Its not plug and play and doese require some Arduino programming. but all you need is a 3.3v FTDi adapter.. and the code comes with an easy to use loader http://code.google.com/p/openlrs/downloads/list

JR / Turnigy module Tx is $29.99

http://www.hobbyking.com/hobbyking/store/__27095__OrangeRx_Open_LRS_433MHz_TX_Module_JR_Turnigy_compatible_.html 
9 Channel Rx is $19.99

Judicious masking and/or VERY careful  removal of electronics board and a Halfords can of Matt Black should fix that!! :laugh:
Let's be careful out there.
SAFETY is.. NO accident.

Jumpy07

Have ordered a TX and RX module with a new Turnigy 9XR.. from HK.. on back order but will report when I get them.

Reading around .. advice is to change the TX antenna to get better range... TBS recommend a SRH-771 Diamond antenna.. managed to get one in UK, will need a right angled adapter as well.

Well the 9XR and the Orange OpenLRS UHF modules finally arrived this morning..!!!!!!!!!! one month from order from Hobby King..
The new 9XR comes already loaded with ER9X and a port installed for future upgrades.

The Orange UHF modules are configured via Arduino. The modules can run at 459Mhz, max 100mw.

The stock ...antennas are very poor, these will be replaced with a 1/2 wave Diamond antenna on the TX and a DIY 1/4 wave on the RX.

This setup should give longer range FPV, but also be less prone to interference and better around hard objects... such as tress and buildings

Have now uploaded latest Firmware to the Orange OpenLRS module, have set them for 459Mhz.

Have use the code that KHA has developed, this is loaded via Arduino using an FTDI adapter..  details here: http://www.rcgroups.com/forums/showthread.php?t=1782034
Code here: https://github.com/kh4/openLRSng

Latest firmware is pretty good, and offers a range of features such as telemetry using the serial ports. PPM SUM and RSSi is also available.. which is great for the TBS. The channels are set up for randomise.. which  is another great feature..  and there is also the ability to use the TX / RX as a spectrum analyser..

The antenna position on the TX module is crap..  and given that the 9XR does not have a stand have made a small bracket to hold the 1/2 wave Diamond antenna, the bracket also serves as a stand. I used a small SMA pigtail to extend the cable to an SMA socket on my DIY bracket. Bracket is bent to allow the antenna to be near upright when in operation.

Have to make a DIY antenna for the RX yet..  and then to install on the TBS and do some range tests

9XR with the tx and rx modules was £94.52 delivered.
You need to add antennas to that.... prob another £30

Would the antena that come with it no good for line of site flying and upgrade later?

Jumpy07

The stock antennas are extremley poor..   prob only any good for 800m
You can make some Sander style antennas if budget is a problem..  just need some right angled SMA plugs and some straws and wire.. this is what I have on the RX.

Before you can use the Hobby King Orange OpenLRS kit you will need to configure them using Arduino.

First download a copy of Arduino


Then download a copy of the latest code from KHA for OpenLRS from here.  https://github.com/kh4/openLRSng/archive/master.zip

Unzip KHA';s code / files into the Arduino directory > Note: They needs to be in a directory called openLRSng

Open up the sketch "openLRSng.ino"

Once open you will need to edit the tab "openLRSng" as detailed below...



UPLOADING:

Use a 3v3 FTDI (or other USB to TTL serial adapter) and Arduino >= 1.0.

set board to "Arduino Pro or Pro Mini (5V, 16MHz) w/ atmega328" (yes it runs really on 3v3 but arduino does not need to know that)

define COMPILE_TX and upload to TX module "or" define COMPILE_RX and upload to RX module

As the Orange OpenLRS system outputs digital PWM RSSi you may need a small RC filter, (as above),  for you OSD if it only accepts analogue.


Without this mod, the RSSI indication on your OSD may not be accurate..

Hiya,

I still can';t seem to get this to work. I';ve tried everything I can think of. All that remains, is to try a different FTDI adaptor. Can you let me know which you used?

I';ve :
1. Downloaded the latest Arduinio
2. Downloaded the 1.7 version of the KH4 code
3. Changed the KH4 code to RX as I';m trying to upload to the RX
4. Connected the FTDI and confirmed that it';s running on COM5 via Device Manager
5. Connected all FTDI pins straight thru except for TX and RX.
6. Used Arduinio Pro or Pro Mini 5V 16MHz w ATmega328
6.1. Done a test compile and it ok.
7. Uploaded... lights flash on both Orange and FTDI... then error
8. Tried with TX and RX straight thru also, but no luck.

With TX RX crossed over i get...

avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0xc0
avrdude: stk500_cmd(): programmer is out of sync

With TX RX straight through i get...

avrdude: stk500_getsync(): not in sync: resp=0x00

Any help would be appreciated as I';m on the verge of giving up and selling and moving to EzUHF!

Thanks hun, Thxx

My transmitter module and receivers turned up yesterday;



I put one of my two receivers in a spare box after flashing it - makes it looks slightly more professional and might add a little protection.

I';ll keep the other one caseless though for the mini hexacopter.

Mmm! Okay, my new FTDI card arrived yesterday and this morning I';ve attempted the reprogramming again, but with no luck. I am convinced the RX is broken, so I unopened the small screws on the TX and changed the line in the arduinio code to TX and upload and WHIPPEEE straight away it all worked. So, to me this just confirms that the RX has a fault! So, I will need to get in touch with HobbyKing to complain! Mmm! This is the first time in a long line of orders when something hasn';t worked! Such a shame, but thanks for all your help guys.

I enabled telemetry before I went on hols.. this sounds the buzzer on link loss..


I only got about 500m and the buzzer was sounding.. but according to my RSSi I still had a good link, and Naza did not go into failsafe...


Not sure if just the buzzer sounding too early.. or if the two way telemetry really reduces the range.. either way have turned telemetry off for now and will rely on Rssi in my OSD.


Telemetry will reduce the range..  but not sure how far.. and wouldnt think it would reduce it to 500m


So if you are having range issues.. might be worth while switching off telemetry .. as below...either 0 or 1

//  0 -- 4800bps, best range, 20Hz update rate
//  1 -- 9600bps, medium range, 40Hz update rate
