We make new modem for diy use. Can be use as a transparent UART modem. Board have also USB to UART converter.
433MHz (414-454MHz) 100mW (20dBm) Super Long Distance LoRa Wireless data modem with USB and UART interface.
General:
LoRa LRS series is a low cost, high performance transparent transceiver with operating at 433MHz. It is LoRa/FSK/ GFSK/OOK modulation variety. It features small size, high output power, high sensitivity, long transmission distance and most of the parameters can be set via the command. Receive and send data to automatically switch. U s e generic UART interface. It is easy to realize the wireless data transmission with only providing the UART data. It is flexible for the users to set the UART baud rate, output power, data rate, frequency select, modulation mode select etc parameters. It is your ideal choice for designing wireless data transmission products which can be widely used on wireless data transmission field.

@Darius,
Saying a component is good for drone use without checking it doesn't interfere is not good but lets think about this for a second - its a low powered 433MHz radio. If I put a new item on one of my rigs I do a few short range, low alt tests before doing anything else. I'm betting most of the people here do the same.
There is currently no requirement for what you are suggesting, pending legislation that is yet to be passed by both houses and not signed into law is likely to end up heavily modified from it's current state. Also note that no system is specified in the text, only that the Administrator has to establish one in 1 year. Lets say it happens with the exact text as it is now, how good is the FAA's track record of this (it will take them 2 to 3 years to get there I predict).
Drone Certified is who's trademark? Where does the text say the AMA does the testing? Why would a company waste valuable resources getting something certified against no set standards for something they don't have to do. Do you think before you type? If you beef is with the legislation take it to people that write the laws, trying to make a point on every post about the implications is counter productive. I'm happy I don't live in the US where we have somewhat sensible RPA rules.
I think I'll now ignore your posts like many others.
@CSG
get full text of the Bill from Senate
testing goes back to AMA ..
so just call AMA and arrange for tests of your data modem installed into drone
Drone Certified (TM) Standard should be applied to every hardware part intended for use with, or installation in a drone.
It makes sense not to install hardware parts not pretested to operate safely with a drone.

‘‘(4) each operator of a test site under section 44802; ‘‘(5) the Center of Excellence for Unmanned Aircraft Systems; ‘‘(6) unmanned aircraft systems stakeholders; and ‘‘(7) community-based aviation organizations. ‘‘(d) FAA APPROVAL.—Not later than 1 year after the date of enactment of the Federal Aviation Administration Reauthorization Act of 2016, the Administrator of the Federal Aviation Administration shall establish a process for the approval of small unmanned aircraft systems make and models based upon safety standards developed under subsection (a). The consensus safety standards developed under subsection (a) shall allow the Administrator to approve small unmanned aircraft systems for operation within the national airspace system without requiring the type certification process in parts 21 and 23 of the Code of Federal Regulations. ‘‘(e) ELIGIBILITY.—The standards for approval of small unmanned aircraft systems developed under this section shall set eligibility requirements for an airworthiness approval of a small unmanned aircraft system which shall include the following:

looks interesting.
find it in http://www.csgshop.com/product.php?id_product=223
What is the difference with a normal 433MHz telemetry solution ??, can you make a comparisson table ?
5Km with 20dBm is nothing: The 5Km path loss at 433MHz is around 100dB (using isotropic antenna's) so with 20dBm transmission power you have -80dBm at the receiver input. I tested my 18$ "3DR radio telemetry..) solution with 0dBm TX power, over 11Km with isotropic antenna's: works perfect (still 20 dB noise margin) as long as you have line of sight and no RF noise from your own PC.
hi, place to buy it ?
@CSG, just ignore Darius, most of what he writes is not relevant.
Looks good, do you have a link and price? The RFD900 (which could perhaps be called an industry benchmark) has a power output of 1000mW, is this also capable of 1W power output? Also what software interface is used to adjust settings or is it compatible with Mission Planner?

Darius, do you have a link for this? Also, what is ""Drone Certified" (TM) Label"? Thx.
Accord FCC,ETSI standard
Are you ready to certify your data modem to meet FAA aircraft grade data modem standards and label it with
"Drone Certified" (TM) Label
In December 2015 FAA upgraded status of DIY Drones to DIY Aircraft Drone,
so any equipment installed in the drone should meet Aircraft Grade Standards set by FAA.
