Tiny 19200 baud 5km radius radio modem

Is there any commercially available tiny (to be carried in model airplane) radio modems capable of communicating (full-dublex) at rate of 19200 baud (or faster) in a radius of up to 5km?

What are you planning ?

There are lots of things capable of many things, however what is IMPORTANT to know is

What country? This affects whether it is even legal to transmit at a suitable power level in that country for the distance or even enough bandwidth and modulation schemes for that baud rate.

Why 5km? As most countries have regulations about line of sight to model airplane that are radio controlled.

Why full duplex? You may be operating in bands that don't permit that for model aircraft.

It may be that I live where there are very few trees, but I can see 5Km on any given day. Is there an actual distance limit in the U.S.

Depends which ANO, which depends on which country you live in. Judging by the list of newsgroups, the OP lives in Australia and I'm not familiar with their ANO.

You may have difficulty getting that kind of range with a license-free solution. I'd advise checking the local regulations to see if there is a band where they allow you enough power output to get 5km range without a directional antenna. As a rough guess, you'll need the best part of 1W output.

there appear to be radio modems on the license exempt 433MHz band which use

20-20mw. a search will produce lots of these products. if you have a directional aerial on the ground and a proper antenna on the other device, you will get the range if it is line of sight.

i suggest that higher power could be used for the tx uplink where power considerations are less severe and a different frequency where interference is reduced to the plane.

note: lipd power limits are higher for some other freqs

Could someone explain the acronym ANO?

If you promise to post replies below what you are replying to, in order to provide context, I'll tell you it stands for Air Navigation Order - the law of the skies.

** How brilliant of you to say that.

The OP is in Australia, so am I and posting on aus.electronics.

From his IP address, he is in Sydney.

** Why are pommies always so keen to boast about their ignorance ??

Is it to justify their infuriating penchant for continually arguing for that same position ??

FYI:

Commonwealth of Australia

Department of Aviation

Air Navigation Orders

Part 95, Section 95.21

re. Model Aircraft

4.1 A model aircraft shall not be flown:

(a) unless visibility permits continuous visual contact by the operator with the aircraft, or

(b) in cloud.

Get off your high horse. The post was cross posted to multiple newsgroups and I for one did not notice it had gone to aus.electronics until it was pointed out.

Let's try to keep this friendly shall we or else retrict your posts to aus.electronics

Look at the newsgroups line in your newsreader. You may be reading only aus.electronics, but *you* have the choice over where the messages you post are distributed. You can quite easily post replies to this thread which go only to aus.electronics, but through ignorance or incompetence you have failed to do so.

My reply was not specific to Australia, nor was it directed at you. It was a reply intended for the global audience among whom this thread is being distributed. It was intended to be useful to the originator of the thread as well as to other interested readers around the world.

I can see you're bitter about the ashes, but it's only once ever couple of decades that we get them back. You'll get over it.

Don't worry, he's mostly a d*****ad. The occasional good advice comes out tho, so we keep him around.

** Here it is again - my words first

" ** The ANO that allows R/C aircraft to fly prohibits all out of visual range operation.

** My post was directed straight at the OP who can easily see that I am in Australia, like him.

Hence, the ANO I alluded to was the appropriate one.

OTOH , Mr Tim Autistic - your f****ng asinine comment served no purpose but to BOAST about what a pig ignorant wanker you are.

Why are pommy turds like Tim always so keen to boast about their ignorance ??

Is it to justify their infuriating penchant for continually arguing from that same position ??

No surprise that are al loathed world wide.

Alan, how old are you (not chronologically, but mentally). I believe we may see some very small numbers here.
