Does the 2.4 ghz radio play well with 2.4 video sy

Recommended Posts

I am using the Futaba 2.4 GHz system and want to get the 2.4 GHZ diversity video system but wanted to know if there are any conflicts that anyone is aware of the whole deal with that radio system is there is not supposed to be, but you know how that goes.

Thanks

no one was able to RC controll on 2.4GHz and have a video 2.4Ghz link on the SAME plane, without problems and degrade of range both ways.

if 900MHz is legal in your area, use 900MHz for the video.

if not, fly on 35-40-72Mhz and then use 2.4GHz for the video.

the small, light and cheap stuff we use is NOT selective enought to be used near other transmitters in the SAME band, sorry, we are not ready to pay what serious stuff cost.

Try doing a search on this forum Steve, this comes up all the time. The simple answer is NO, it will interfere but some have had some success at shorter ranges.

I am mainly trying to monitor my digital camera but if I could do some video that would be great since the futaba radio is a diversity system would it make any differance if I got a diversity video/photo setup.

Also I'm not to against changing the radio if the video system is best on the 2.4 ghz setup. Or am I better doing a 900 MHz setup and leaving radio the way it is. The only problem is the only digital camera monitor setup I found that is not 2.4GHz wont respond to my email attempts make me wonder about there service.

Thanks for your time in advance.

>wont respond to my email attempts make me wonder about there service

so go someplace else !

the internet is FULL of radio links for video freaks like us,

I would have suggested Rangevideo - BlackWiddowVideo - RC-Tech

and so on and so on, you might even find a compleete list of parts / stuff vendors on this forum ?!?! if not, lets make one !

Problem with the 900MHz is that is is a GSM band in Europe and much of the rest of the world.

I-ve just been trying to figure out what frequencies are legal in Europe. On the site of our national Telecom Agency I-ve found the National Frequency Register (http://www.agentschap-telecom.nl/nfr/index.html) and in there the following which seem to be "license free" frequencies which I guess would be the frequencies we're limited to for our purposes and dependent upon available systems.

2400 MHz 2483.5 MHz Non specific SRD No 10 mW e.i.r.p. All kHz 100%

122 GHz 123 GHz Non specific SRD No 100 mW e.i.r.p. All kHz 100%

244 GHz 246 GHz Non specific SRD No 100 mW e.i.r.p. All kHz 100%

I believe 433 and 868 are used for some telemetry. Not sure whether there are any good usable AV links over those and how much risk an AV link on those bands would introduce or run for interference with other systems on those bands
