Yes, The Futaba type of spread spectrum modulation (FHSS) is generally more prone to errors because of only one active channel at any time, that will now-and then hit some "busy" frequency .. when that happens often, there will be trouble.

Hi Andre and all the others,
Sorry for the others but first post... have been working on VR for about 3 years now and it has been pretty much a lself earning experience all the way...

I started with and easystar and with just a CMOS self contain camera at 10 Mw.. Being an Aussie we are on 36Mhz and I started pre 2.4 TX days.
My background is as a HAM operator..
This post could go on for just about ever and most, I would have to say has more than likely been said already in this forum.

So equipment I use... JR 9xVer11 36 meg.. not good for the headtacker R1.. port assigment issues..
Bought a Futaba 9CHP to solve that problem.
Also use a DX7 2.4 but not with the video TX of 500mw and 1000w.. always stay with X2 different freq in VR. much safer and the futaba get me around 3 miles. :D using pal cam.. OSD, GPS,

Interested in you comments about the compatibility issue I have a 2.6 m Ventus and could get the AR7000 and the 500mw video TX well away.. but I consider the problem that a RX failure could be very expensive .. range is reduced condsiderably!!!!!

As I get time to look through this forum and not repeat postings .. I will be able to become more active and assist...
I have not done a lot of VR latley or at least video posts.. have some on youtube user name "RichardVRFlyer" in my earlier days... using sail servos to get close to 360 degree pan.
using a patch 8dbi and a bi pole for RX.
Using swithmode voltage regulator for different votltages for dropping from 11.1v lipo and up from 5 v to 12v low loss ,low and heat
Glad to answer any questions when I can have, I moved into Slope and thermal flying.. which make this type of flying even more of a challenge.
enough said.
Cheers
Richard

I use 2.4Ghz radio so have been considering 1.3Ghz or 900Mhz video transmitters. Any reason you want to stick with 2.4Ghz for video?
