JR mx 12 long range TX

Posted by Robert Krogh (hooks) on June 1, 2009 at 3:30pm

My JR mx12 FM 35 Mhz TX got an overhaling made by Thomas Scherrer.FM 35 Mhz 10 mW - UHF 433 Mhz 500 mW ( secret button1,3 W)

Replacement of the FM tx to the new long range UHF tx.

OLD FM TX

New UHF TXDon't have to think about channel or "range" anymore.With a Yagi antenna and the new tracking antenna from immersion I hope to get a good range. My goel is about 15-20 km.(Did I mention the 7W booster I also ordered from Thomas Scherrer shhhhh).I'll gess the video link will be the week point now.More will come about this new option.

tx, longe, range

Just a note: somewhere the regs also state "unaided line of sight", so binoculars are out too.

But then what about those high flying gliders I've seen thermalling at several thousand feet and the operator using a lounge chair with binoculars built into the arm??

Hooks, Denmark has signed up for the Europe wide sUAS regulations flight outside of VLOS will be illegal.

Its not that anyone will come and chase you down for flying outside of VLOS but the first person to have a complaint raised against them, be it flying into a greenhouse or just a member of the public that the trouble will start.

Here in the UK the CAA will do nothing until it has received a complaint and then if it considers the complaint to be serious enough it will continue.

If you choose to do it, its upto you but better not publicise it. Matter not that you think its safe.

It's a bit funny.
You have the rights to own a weapon, I gess nearly every citizen in the US have a gun under there bedpillow. But using a LRS for RC flying is a national threat..
Sorry I don't get it.
Here in Denmark we need a licens for having a airgun, but at the same time you can use LRS for oure RC plane. Hope everyone can see the picture.

I'm also a very satisfied user of this system since end of last year. I don't fly out of sight but the system is extremely secure and I don't disturb all the other R/C mates on 35 Mhz around of my flight area here.

Are you kidding?? Posting maybe not, but watching, you betcha!

Cheap autonomous flight controllers? High powered R/C transmitters?

I'm sure more than a few "baddies", and the Homeland Security guys have browsed these pages.

Hooks: does the response work as quickly as with the 35Mhz old system?
I'm fiddling with a 868Mhz radio system based on a CC1101 tranceiver but not very close yet, but I was wondering about delays in this Long Range system.
For US people: in Europe LRS is becoming more and more common for FPV/UAV use, although most countries limit flight to within line of sight. I have not heard of any real issues happening with people using them.

It seem to me that alot of US RC people don't like this Long Range System.. Maybe we have alot to learn here in Europe or maybe US don't need to be so pernoid I don't know. It's not like you don't have the space for flying over there. I think I'll get my head out the this fire.. By the way... The system are so great you won't belive it.

Thanx for all your opinions.

@ Gary Mortimer :

And some country don't care ......

In France you can use whatever you want , nobody said a word.
Many people fly with 1W video Tx and UHF radio , nothing to worry about.

Everybody and his/her dog is up in arms about "See and Avoid" Its NOT about knowing where you are or are going, it is about avoiding other air traffic. The more of this type of un authorized flight is discovered, the less scope will be left over for others to fly.

Rgrds n keep a cool head...

I dont want to start a flame war so I shall pull my head in.

I see your reasons, but flight outside of VLOS is a tricky subject
